# Spondylosis Deformans in Dogs: Spinal Bone Spurs, Pain and Management ## Key Takeaways - Spondylosis deformans is a common, non-inflammatory, degenerative condition characterized by the formation of osteophytes (bone spurs) on vertebral bodies, typically along the ventral and lateral aspects, often at ligament attachment sites. - Diagnosis is primarily achieved through radiography (X-rays), which clearly visualizes the characteristic bony projections, with advanced imaging like MRI or CT reserved for complex cases or when neurological deficits are present. - While often an incidental finding, pain associated with spondylosis can arise from nerve impingement by large spurs, secondary musculoskeletal strain due to altered spinal biomechanics, or concurrent spinal conditions like intervertebral disc disease (IVDD). - Management focuses on pain control and maintaining mobility through a multimodal approach, including weight management to reduce spinal load, controlled low-impact exercise, physical therapy, and veterinary-prescribed analgesics such as NSAIDs. - Prevention strategies involve maintaining a lean body condition, providing supportive environmental modifications (e.g., ramps), and ensuring balanced, low-impact exercise to minimize chronic spinal stress. --- If your [dog](/knowledge/veterinary-medicine/clinical-methods/dog) has been diagnosed with spondylosis deformans, you are likely wondering what these spinal bone spurs mean for their comfort and mobility. The short answer is that spondylosis deformans is a common, age-related condition where bony projections, called osteophytes or bone spurs, form along the edges of the vertebrae. For many dogs, these spurs are an incidental finding that causes no pain. However, in a significant number of cases, they can lead to stiffness, discomfort, and reduced quality of life. This article provides a definitive, source-grounded guide to understanding, diagnosing, and managing this condition. **Owner Triage Summary:** If your dog is showing signs of back pain, such as reluctance to jump, stiffness when getting up, or crying out when touched, you should schedule a veterinary examination promptly. Do not attempt to massage the spine deeply or give human pain medications. While spondylosis itself may not be an emergency, the symptoms can mimic more serious conditions like intervertebral disc disease (IVDD) or spinal tumors, which require immediate professional attention. ## At a Glance: Understanding Spondylosis Deformans | Feature | Typical Description | | :--- | :--- | | **What is it?** | A non-inflammatory, degenerative condition characterized by bony spurs (osteophytes) forming on the vertebral bodies, often at the sites of ligament attachment [1]. | | **Common Location** | Most frequently found in the thoracolumbar and lumbar spine (lower back) [1][2]. | | **Primary Cause** | Chronic instability or wear and tear on the spinal column, leading to calcification of spinal ligaments [3]. | | **Is it painful?** | Not always.

Spondylosis deformans is a degenerative condition of the spine, not an inflammatory one. The term "deformans" refers to the change in the shape of the vertebrae due to the formation of new bone. These bony projections, known as osteophytes or bone spurs, typically develop on the ventral (bottom) and lateral (side) aspects of the vertebral bodies [1]. They often look like small to large bony lips or bridges spanning the intervertebral disc space. This condition is distinct from another similar disease called Diffuse Idiopathic Skeletal Hyperostosis (DISH). While both involve new bone formation, DISH is characterized by the ossification of the long spinal ligaments, particularly the ventral longitudinal ligament, often resulting in a continuous, flowing bridge of bone across multiple vertebrae. Spondylosis deformans, in contrast, typically involves more localized spur formation at the attachment points of the annulus fibrosus of the intervertebral disc [1]. In human medicine, DISH is also known as Forestier's disease, and canine DISH is considered a valuable model for studying this human condition [3]. ### The Anatomy of a Bone Spur To understand spondylosis, it helps to visualize the spine. It is made up of individual bones called vertebrae, which are separated by shock-absorbing structures called intervertebral discs. Strong ligaments run along the length of the spine, providing stability. In spondylosis, the body attempts to stabilize a spinal segment that has become unstable due to disc degeneration or other stresses. It does this by producing new bone at the points where the ligaments and the outer ring of the disc (annulus fibrosus) attach to the vertebrae [1]. This new bone is the bone spur. ## Causes and Risk Factors: Why Does It Happen? The exact cause of spondylosis deformans is not fully understood, but it is widely considered a result of chronic, low-grade instability and biomechanical stress on the spine [3]. As the intervertebral discs degenerate with age, they lose height and their shock-absorbing capacity. This creates micro-movement and instability in the spinal segment. The body's natural response is to reinforce the area by laying down new bone, resulting in the characteristic spurs. Several factors can increase a dog's risk of developing spondylosis: - **Age:** The condition is strongly associated with aging. The prevalence of spondylosis increases significantly with each year of life. - **Breed and Size:** Large and giant breed dogs are more commonly affected. A specific study on Rottweilers found a high prevalence of the condition [4]. - **Genetics and Conformation:** Certain breeds may have a genetic predisposition. The study on tailed versus tail-docked Rottweilers suggests that the presence of a tail, which provides natural balance and counterbalance, may influence the biomechanical forces on the spine and thus the development of spondylosis [4]. - **Spinal Stress and Activity:** Historically, the condition has been observed in working dogs. A study on search-and-rescue dogs found a high incidence of thoracic spondylosis deformans, suggesting that the physical demands of their work may contribute to the condition [5]. - **Trauma:** Previous injury to the spine can lead to instability and subsequent spur formation. ## Is Spondylosis Deformans Painful? The Clinical Picture This is the most critical question for any dog owner. The answer is complex: **spondylosis deformans can be painful, but it is frequently an incidental finding.** The bone spurs themselves are not inherently painful. However, they can cause pain in several ways: - **Nerve Impingement:** If a spur grows large enough, it can compress the spinal cord or the nerve roots as they exit the spinal column. This can cause neurological signs like weakness, ataxia (wobbliness), or pain. - **Musculoskeletal Pain:** The altered biomechanics of the spine can cause muscle strain and pain in the surrounding back and hind limb muscles. - **Associated Conditions:** Spondylosis is often seen alongside other spinal diseases, such as intervertebral disc disease (IVDD). In these cases, the pain may be primarily from the IVDD, not the spondylosis itself. ### Recognizing the Signs in Your Dog Many dogs show no clinical signs at all. When signs do appear, they are often subtle and can be mistaken for normal aging. Owners may notice: - Stiffness, especially after rest or in cold weather. - Reluctance to jump onto furniture or into the car. - Difficulty getting up or lying down. - Reduced activity levels or reluctance to play. - A "bunny-hopping" gait in the hind legs. - Sensitivity or pain when the back is touched or stroked. - Vocalizing (whining or yelping) when moving or being picked up. - In severe cases, weakness or incoordination in the hind limbs. It is crucial to remember that these signs are not exclusive to spondylosis. They can also be caused by IVDD, spinal tumors, arthritis in the hips or knees, or other neurological conditions. A thorough veterinary examination is essential for an accurate diagnosis. ## How Veterinarians Diagnose Spondylosis Deformans Diagnosis is typically straightforward and relies heavily on imaging. ### 1. Physical and Neurological Examination Your veterinarian will start with a full physical exam, including a detailed neurological assessment. They will palpate (feel) along your dog's spine to check for pain or muscle spasms and assess your dog's gait, posture, and spinal reflexes. This helps determine if the issue is orthopedic or neurological and helps localize the problem. ### 2. Radiography (X-rays) X-rays are the primary diagnostic tool for spondylosis deformans. The characteristic bone spurs are usually easily visible on a lateral (side-on) view of the spine [1][2]. The thoracolumbar and lumbar regions are the most common sites for these changes [1]. In some cases, advanced imaging is needed. One study highlighted that while X-rays are excellent for identifying the bony changes of spondylosis, they may not fully reveal the extent of spinal cord compression, which can be better assessed with Magnetic Resonance Imaging (MRI) [1]. This is particularly important if your dog is showing neurological signs. ### 3. Advanced Imaging (MRI and CT) If your dog is experiencing significant pain or neurological deficits, an MRI or CT scan may be recommended. These provide a much more detailed view of the spinal cord, nerve roots, and soft tissues. This is crucial for distinguishing spondylosis from other causes of spinal pain, such as a herniated disc or a spinal tumor, and for planning any potential surgical intervention [1][6]. ### A Note on Incidental Findings Because spondylosis is so common, especially in older dogs, it is often discovered incidentally when X-rays are taken for another reason, such as a suspected hip problem or a pre-anesthetic screening. In these cases, the presence of spurs does not automatically mean they are the source of the dog's problem. Your vet will correlate the X-ray findings with your dog's clinical signs to determine if the spondylosis is significant. ## Evidence-Based Management: How to Help Your Dog There is no cure for spondylosis deformans, as the bony changes are permanent. However, the condition can be managed effectively to control pain and maintain a good quality of life. The goal of treatment is to manage clinical signs, not to reverse the bone growth. Management strategies are tailored to each individual dog, depending on the severity of their signs. According to the American Animal Hospital Association (AAHA) pain management guidelines, a multimodal approach is often most effective. This means combining different types of treatments to achieve better pain control with fewer side effects. ### 1. Weight Management and Nutrition Maintaining a lean body condition is arguably the single most important factor in managing any orthopedic condition, including spondylosis. Excess weight puts significant additional stress on the spine and joints. If your dog is overweight, your veterinarian can help you develop a safe and effective weight loss plan. ### 2. Controlled Exercise and Physical Therapy While rest is important during acute flare-ups, chronic rest is detrimental. A controlled exercise program helps maintain muscle mass, which supports the spine, and keeps joints lubricated. - **Leash Walks:** Regular, short, on-leash walks on soft, even surfaces are ideal. Avoid high-impact activities like running, jumping, and rough play. - **Physical Therapy:** Canine rehabilitation therapy, including therapeutic exercises, hydrotherapy (swimming or underwater treadmill), and massage, can be incredibly beneficial. A certified canine rehabilitation therapist can design a program specific to your dog's needs. ### 3. Pain Management If your dog is in pain, your veterinarian may prescribe medications. It is critical to **never** give your dog human pain relievers like ibuprofen, naproxen, or acetaminophen, as these are highly toxic to dogs and can be fatal. Veterinary-prescribed options may include: - **Non-Steroidal Anti-Inflammatory Drugs (NSAIDs):** These are the most common class of drugs used to manage pain and inflammation in dogs with musculoskeletal conditions. They are used to control the pain associated with the condition. - **Other Analgesics:** For dogs with more severe pain, veterinarians may use other medications, such as gabapentin or amantadine, often in combination with an NSAID. - **Joint Supplements:** While not strictly for pain, supplements like glucosamine and chondroitin sulfate are often recommended to support overall joint health. Their efficacy for spinal pain is not as well-established as for other joints, so discuss this with your vet. ### 4. Alternative and Adjunctive Therapies Many owners find benefit in complementary therapies, which can be used alongside conventional medicine. These should always be discussed with your veterinarian first. - **Acupuncture:** This can be effective for managing chronic pain in dogs. - **Laser Therapy (Photobiomodulation):** This non-invasive treatment uses specific wavelengths of light to reduce pain and inflammation. - **Chiropractic or Manual Therapy:** Some dogs benefit from gentle, veterinary-administered manual therapy to improve spinal mobility, but this should only be performed by a qualified professional and is contraindicated in cases of spinal instability or severe disc disease. ## Unsafe Home Remedies and What to Avoid When your dog is stiff or in pain, your instinct may be to help. However, some well-intentioned actions can cause more harm than good. - **Human Medications:** This cannot be overstated. Human pain relievers are dangerous and potentially lethal to dogs. - **Deep Tissue Massage:** While gentle massage can be relaxing, deep tissue massage over the spine can exacerbate pain and inflammation, especially if the area is sensitive. - **Forceful Stretching:** Never force your dog's limbs or back into positions they are resisting. This can cause injury. - **Unsupervised Exercise:** Do not let your dog self-regulate exercise. A dog in pain may still overdo it, leading to a flare-up. You must control their activity level. ## Prevention and Long-Term Prognosis ### Can Spondylosis Be Prevented? There is no guaranteed way to prevent spondylosis, as it is largely a consequence of aging and genetics. However, you can reduce the risk factors you can control: - **Maintain a Healthy Weight:** This reduces stress on the entire spine. - **Provide a Supportive Environment:** Use ramps instead of stairs or jumps for getting on and off furniture and into the car. - **Balanced, Low-Impact Exercise:** Keep your dog fit with regular, controlled exercise to maintain strong supporting muscles without causing excessive spinal stress. ### Prognosis The prognosis for a dog with spondylosis deformans is generally good. Most dogs can live a comfortable, happy life with appropriate management. The condition is not life-threatening, and the primary goal is to manage pain and maintain mobility. The key is early detection and proactive management to prevent the condition from significantly impacting your dog's quality of life. In severe cases where the bone spurs cause significant spinal cord compression, surgery may be an option, though it is complex and typically only recommended when medical management has failed [6]. The decision to pursue surgery would be made by a veterinary neurologist or surgeon after advanced imaging. ## Limitations and When to Contact a Veterinarian This article provides a comprehensive overview of spondylosis deformans, but it is educational and is not a substitute for veterinary diagnosis or treatment. Every dog is an individual, and the way spondylosis affects one dog may be completely different from how it affects another. It is important to understand that breed-level information, such as the higher prevalence in Rottweilers or working dogs, cannot predict what will happen in your specific pet [5][4]. These are statistical associations, not guarantees. Your dog's clinical signs, overall health, and response to therapy are what matter most. **You should contact your veterinarian immediately if you notice any of the following red flags:** - **Sudden paralysis or severe weakness** in the hind legs. - **Loss of bladder or bowel control.** - **Severe, unrelenting pain** that is not controlled with prescribed medication. - **A sudden change in behavior** or a refusal to eat or drink. - **Any signs of neurological dysfunction**, such as dragging a limb, severe incoordination, or head tilt. These signs could indicate a more serious condition, such as a spinal tumor, a severe disc herniation, or another neurological disorder that requires immediate intervention [6]. ## The Biomechanics of Spinal Instability and Spur Formation Understanding why spondylosis deformans develops requires a closer look at the biomechanics of the canine spine. The vertebral column is a complex system of bones, discs, ligaments, and muscles that work together to provide both stability and flexibility. When any component of this system becomes compromised, the body attempts to compensate, and it is this compensatory process that leads to the formation of bone spurs. The intervertebral disc serves as the primary shock absorber between vertebrae. With age and repeated mechanical stress, the nucleus pulposus, the gelatinous center of the disc, gradually loses its water content and its ability to distribute pressure evenly across the vertebral endplates [1]. This degenerative process, known as chondrodystrophic degeneration, leads to a reduction in disc height and a loss of normal tension within the annulus fibrosus, the tough outer ring of the disc. As the disc loses height, the distance between adjacent vertebrae narrows, and the normal biomechanical relationship between the vertebral bodies is altered. This altered relationship creates a state of segmental instability. The spinal segment, now lacking its normal shock-absorbing capacity, experiences abnormal micro-motion during everyday activities such as walking, running, and even standing. The body's response to this instability is to attempt to stabilize the segment by depositing new bone at the sites where the annulus fibrosus and the longitudinal ligaments attach to the vertebral bodies [1]. These bony proliferations, the osteophytes, are essentially the spine's attempt to fuse the unstable segment and prevent further abnormal movement. The distribution of these spurs is not random. They tend to form most commonly on the ventral and lateral aspects of the vertebral bodies, precisely where the mechanical stress is greatest [1]. The thoracolumbar junction, the area where the thoracic spine meets the lumbar spine, is a particularly common site for spur formation. This region is a natural transition zone between the relatively rigid thoracic spine, which is attached to the rib cage, and the more mobile lumbar spine. This transition creates a biomechanical fulcrum point where stress concentrates, making it a prime location for degenerative changes [1][2]. It is important to recognize that spondylosis deformans is a dynamic process, not a static one. The bone spurs can continue to grow and change over time. In some dogs, the spurs may eventually bridge the intervertebral space, creating a solid bony connection between adjacent vertebrae. While this bridging might seem like a concerning development, it can actually represent the spine's successful attempt to stabilize the segment. Once a complete bony bridge forms, the segment is effectively fused, and the instability that drove the spur formation is resolved. This is why some dogs with advanced, heavily bridged spondylosis may actually show fewer clinical signs than dogs with early, active spur formation. ## The Spectrum of Clinical Presentation The clinical presentation of spondylosis deformans exists on a broad spectrum, ranging from completely asymptomatic to severely debilitating. Understanding this spectrum is essential for owners who may be trying to interpret their dog's behavior and decide when to seek veterinary care. At one end of the spectrum are dogs with radiographic evidence of spondylosis who show no clinical signs whatsoever. These dogs are often diagnosed incidentally when X-rays are taken for unrelated reasons, such as a dental cleaning, a pre-anesthetic screening, or an evaluation for a suspected hip problem. The bone spurs are present, sometimes even extensive, but the dog's mobility, comfort level, and quality of life are completely unaffected. In these cases, the spondylosis is truly an incidental finding, and no treatment is required beyond routine wellness care. Moving along the spectrum, there are dogs who experience subtle, chronic changes in their mobility and behavior. These changes are often insidious in onset and may be attributed to "normal aging" by owners. A dog may take a little longer to get up from a lying position, may hesitate before jumping onto the couch, or may be less enthusiastic about long walks. These signs can be intermittent, appearing worse after rest or in cold, damp weather, and improving with gentle activity. Owners may not even recognize these as signs of pain, interpreting them instead as the dog simply slowing down with age. Further along the spectrum are dogs with more obvious signs of pain and discomfort. These dogs may vocalize when getting up or lying down, may flinch or cry out when their back is touched, and may show a noticeable reduction in their activity level. They may be reluctant to climb stairs, jump into the car, or engage in play. Their gait may become stiff and stilted, and they may develop a "bunny-hopping" gait in their hind legs, where both hind feet move together rather than in an alternating pattern. This gait change is often a compensatory mechanism to reduce spinal movement and minimize pain. At the most severe end of the spectrum are dogs with significant neurological deficits. These occur when bone spurs grow large enough to compress the spinal cord or the nerve roots as they exit the vertebral canal. The resulting signs can include weakness in the hind limbs, incoordination (ataxia), a dragging of the toes, and in severe cases, paralysis. Urinary or fecal incontinence can also occur if the compression affects the nerves that control bladder and bowel function. These neurological signs are a red flag that requires immediate veterinary attention, as they may indicate a more serious condition than uncomplicated spondylosis [6]. ## The Diagnostic Workflow in Detail The diagnostic journey for a dog with suspected spondylosis deformans typically follows a structured workflow that begins with a thorough history and physical examination and progresses to imaging studies. ### The Importance of a Detailed History The first step in the diagnostic process is a comprehensive history. Your veterinarian will ask you detailed questions about your dog's age, breed, activity level, and any changes in behavior or mobility you have observed. They will want to know when the signs first started, whether they have been progressive or intermittent, and what makes them better or worse. Specific questions may include: - Does your dog have difficulty getting up from a lying or sitting position? - Is your dog reluctant to jump onto furniture or into the car? - Has your dog's activity level decreased? - Does your dog seem stiff after rest or in cold weather? - Does your dog vocalize or flinch when touched on the back? - Has your dog had any previous injuries or trauma? - Has your dog been diagnosed with any other health conditions? This information helps the veterinarian understand the nature and duration of the problem and can provide important clues about the underlying cause. ### The Neurological Examination Following the history, your veterinarian will perform a complete physical examination, with particular emphasis on the neurological system. The neurological examination is a systematic assessment of the nervous system that helps localize the site of any neurological dysfunction. It includes: - **Gait assessment:** The veterinarian will observe your dog walking and trotting, looking for signs of weakness, incoordination, or abnormal gait patterns. - **Postural reactions:** These tests assess the dog's ability to correct abnormal limb positions and include tests such as proprioceptive placing, hopping, and hemiwalking. - **Spinal reflexes:** The veterinarian will test reflexes such as the patellar reflex, the withdrawal reflex, and the perineal reflex to assess the function of specific nerve roots and spinal cord segments. - **Palpation:** The veterinarian will gently palpate along the entire length of the spine, feeling for areas of muscle spasm, pain, or bony abnormalities. - **Cranial nerve assessment:** This evaluates the function of the nerves that originate in the brainstem and is important for ruling out conditions affecting the brain. The results of the neurological examination help the veterinarian determine whether the problem is orthopedic, neurological, or both, and helps localize the lesion to a specific region of the spine. ### Radiographic Evaluation If spondylosis deformans is suspected, radiographs (X-rays) are the next step. Radiographs are excellent for visualizing the bony changes characteristic of spondylosis [1][2]. The spurs appear as bony projections extending from the vertebral bodies, and they are typically most visible on a lateral (side-on) view of the spine. Standard radiographic views for evaluating the spine include: - **Lateral view:** The dog is positioned on its side, and the X-ray beam is directed from side to side. This view is best for visualizing the ventral and dorsal aspects of the vertebral bodies and is the primary view for identifying spondylosis. - **Ventrodorsal view:** The dog is positioned on its back, and the X-ray beam is directed from the belly toward the back. This view is best for visualizing the lateral aspects of the vertebrae and can help identify spurs that are not visible on the lateral view. In some cases, the veterinarian may recommend a stressed or flexed view, where the spine is positioned in a specific way to better visualize the intervertebral spaces and assess for instability. While radiographs are excellent for identifying the presence of bone spurs, they have limitations. They cannot show the spinal cord, nerve roots, or other soft tissues. This means that radiographs alone cannot determine whether a bone spur is compressing the spinal cord or whether there is concurrent disc disease or other soft tissue pathology [1]. If your dog is showing neurological signs, advanced imaging will be necessary. ### Advanced Imaging: MRI and CT Magnetic Resonance Imaging (MRI) and Computed Tomography (CT) are advanced imaging modalities that provide far more detail than radiographs. - **MRI** is the gold standard for evaluating the soft tissues of the spine, including the spinal cord, nerve roots, intervertebral discs, and ligaments. It can clearly show whether a bone spur is compressing the spinal cord and can identify concurrent conditions such as intervertebral disc herniation, spinal tumors, or inflammation [1]. MRI is particularly valuable when a dog is showing neurological signs, as it can help distinguish between spondylosis and other more serious conditions. - **CT** is excellent for evaluating bony structures and can provide three-dimensional reconstructions of the spine. It is particularly useful for surgical planning, as it can show the exact size, shape, and location of bone spurs and their relationship to the spinal cord and nerve roots. The decision to pursue advanced imaging is based on the severity of the clinical signs, the findings on the neurological examination, and the results of the radiographs. If a dog has mild, non-progressive signs and radiographs show typical spondylosis changes, advanced imaging may not be necessary. However, if a dog has significant pain, neurological deficits, or signs that are not explained by the radiographic findings, advanced imaging is strongly recommended. ## Owner Observation and Preparation for a Veterinary Visit Owners play a crucial role in the diagnosis and management of spondylosis deformans. Your observations of your dog's behavior at home are invaluable to the veterinarian, as they provide information that cannot be obtained from an examination in the clinic. Dogs often behave differently in the veterinary hospital, and they may hide signs of pain or weakness that are obvious at home. ### What to Observe and Document Before your veterinary visit, take some time to observe your dog carefully and document what you see. This information will help your veterinarian make a more accurate diagnosis and develop a more effective treatment plan. **Mobility and Gait:** - Does your dog have difficulty getting up from a lying or sitting position? - Does your dog seem stiff when first getting up, and does the stiffness improve with movement? - Is your dog reluctant to jump onto furniture, into the car, or up stairs? - Does your dog have a normal gait, or is there a limp, a bunny-hopping gait, or a swaying of the hindquarters? - Does your dog drag its toes or knuckle its [paws](/knowledge/veterinary-medicine/clinical-methods/paws) when walking? - Does your dog tire easily on walks? **Pain and Discomfort:** - Does your dog vocalize (whine, yelp, cry) when getting up, lying down, or being touched? - Does your dog flinch or pull away when you pet its back? - Does your dog seem restless or unable to get comfortable? - Does your dog pant excessively without an obvious cause? - Does your dog show a change in appetite or behavior? **Elimination Habits:** - Has your dog had any accidents in the house? - Does your dog have difficulty squatting to urinate or defecate? - Has there been any change in the frequency or volume of urination? - Does your dog strain to defecate? **Activity Level:** - Has your dog's overall activity level decreased? - Is your dog less interested in play or walks? - Does your dog spend more time sleeping or resting? - Is your dog less interactive with family members? **Environmental Factors:** - Have there been any recent changes in your dog's environment or routine? - Has your dog had any recent injuries or falls? - Does your dog sleep on a hard or soft surface? - Are there stairs in your home that your dog must navigate? ### How to Prepare for the Veterinary Visit Once you have documented your observations, you can prepare for the veterinary visit. Here are some steps you can take to make the visit as productive as possible: 1. **Bring your documentation:** Write down your observations and bring them to the appointment. This ensures you do not forget important details during the stress of the visit. 2. **Bring a video:** If possible, take a video of your dog's gait and mobility at home. A video can be incredibly helpful, as it shows the veterinarian how your dog moves in its normal environment. 3. **Bring a list of medications:** Make a list of all medications, supplements, and preventives your dog is currently taking, including the doses and frequency. 4. **Bring medical records:** If your dog has been seen by another veterinarian, bring copies of any relevant medical records, including previous X-rays or lab work. 5. **Prepare questions:** Write down any questions you have for the veterinarian so you do not forget to ask them during the appointment. 6. **Be prepared to discuss your dog's lifestyle:** The veterinarian will want to know about your dog's diet, exercise routine, and living environment. ### Questions to Ask Your Veterinarian When you are at the veterinary appointment, do not hesitate to ask questions. It is your right to understand your dog's condition and the recommended treatment plan. Some questions you may want to ask include: - What is the likely cause of my dog's signs? - Are the bone spurs I see on the X-rays definitely the cause of my dog's pain? - What other conditions could be causing my dog's signs? - What diagnostic tests do you recommend, and why? - What are the treatment options, and what are the risks and benefits of each? - What is the prognosis for my dog? - What should I do if my dog's signs worsen? - Are there any activities or exercises I should avoid? - What signs should prompt me to call you immediately? ## Evidence Limitations and the Importance of Individualized Care It is important to understand the limitations of the scientific evidence regarding spondylosis deformans in dogs. While research studies provide valuable insights into the condition, they cannot predict what will happen in any individual dog. Many of the studies on spondylosis deformans are observational, meaning they describe the prevalence and characteristics of the condition in specific populations of dogs. For example, studies have shown a high prevalence of spondylosis in Rottweilers and in working dogs such as search-and-rescue dogs [5][4]. These studies are valuable because they identify risk factors and help veterinarians understand which dogs are more likely to develop the condition. However, they do not tell us whether a specific Rottweiler or a specific search-and-rescue dog will develop spondylosis or, if they do, whether it will cause clinical signs. Another limitation of the evidence is that much of what we know about the pain associated with spondylosis is based on clinical experience and extrapolation from human medicine. In human medicine, the relationship between spinal bone spurs and pain is complex and not fully understood. Many people with extensive bone spurs have no pain, while others with minimal spurs have significant pain. The same is likely true in dogs, which means that the presence of bone spurs on an X-ray does not necessarily mean they are the cause of a dog's clinical signs. This is why the diagnostic process is so important. Your veterinarian will not simply look at the X-rays and make a diagnosis. They will correlate the radiographic findings with the results of the physical and neurological examination and with your observations of your dog's behavior at home. This holistic approach is essential for determining whether the spondylosis is clinically significant and for developing an appropriate treatment plan. It is also important to recognize that spondylosis deformans is often not the only problem. Many older dogs have multiple concurrent conditions, such as osteoarthritis of the hips, knees, or elbows, intervertebral disc disease, or other age-related health issues. These conditions can interact with each other, making the clinical picture more complex. For example, a dog with both hip arthritis and lumbar spondylosis may have difficulty getting up due to the hip pain, which in turn places additional stress on the already compromised lumbar spine. In these cases, the treatment plan must address all of the dog's conditions, not just the spondylosis. ## Prevention Strategies and Environmental Modifications While there is no guaranteed way to prevent spondylosis deformans, there are steps you can take to reduce your dog's risk and to minimize the impact of the condition if it does develop. These strategies focus on reducing stress on the spine and maintaining overall musculoskeletal health. ### Weight Management as Primary Prevention Maintaining a lean body condition is the single most important preventive measure for spondylosis and for virtually all other orthopedic conditions. Excess body weight places significant additional stress on the spine, the intervertebral discs, and the supporting ligaments. This increased stress accelerates the degenerative changes that lead to spur formation and increases the likelihood that any existing spurs will cause clinical signs. A study on the prevalence of spondylosis in different breeds found that body weight is a significant risk factor [4]. Overweight dogs are more likely to develop spondylosis and are more likely to experience pain from the condition. If your dog is overweight, work with your veterinarian to develop a safe and effective weight loss plan. This typically involves a combination of dietary modification and increased exercise, with the goal of achieving a gradual, steady weight loss. ### Exercise and Muscle Conditioning Regular, controlled exercise is essential for maintaining the muscle mass that supports the spine. Strong paraspinal muscles act as a natural brace for the spine, reducing the load on the intervertebral discs and ligaments. A dog with good muscle condition is less likely to experience spinal instability and less likely to develop spondylosis. However, the type and amount of exercise matter. High-impact activities, such as jumping, running on hard surfaces, and rough play, can place excessive stress on the spine and may accelerate degenerative changes. Low-impact activities, such as walking on soft, even surfaces, swimming, and controlled play, are safer and more beneficial for spinal health. The key is to find a balance between keeping your dog fit and avoiding excessive spinal stress. For most dogs, regular, moderate exercise is ideal. Puppies and young dogs should be allowed to play and develop normally, but they should not be encouraged to jump from heights or engage in repetitive high-impact activities. ### Environmental Modifications Simple modifications to your dog's environment can reduce the stress on the spine and make daily activities easier and safer. - **Ramps:** If your dog is allowed on furniture or needs to get into a car, consider using a ramp instead of allowing them to jump. Jumping places significant stress on the spine, particularly the lumbar region, and can exacerbate spondylosis. - **Non-slip flooring:** Slippery floors can cause your dog to slip and fall, which can lead to injury and increased spinal stress. Use area rugs or non-slip mats in areas where your dog walks and plays. - **Supportive bedding:** Provide your dog with a comfortable, supportive bed that cushions the spine. Orthopedic foam beds are a good option for older dogs. Avoid letting your dog sleep on hard, cold surfaces. - **Elevated food and water bowls:** Raising the food and water bowls can reduce the need for your dog to bend its neck and back to eat and drink, which can be beneficial for dogs with cervical or thoracic spondylosis. - **Stair gates:** If your dog has difficulty with stairs, consider using a gate to restrict access to upper floors. Carrying your dog up and down stairs can be an alternative for small dogs. ### Nutritional Considerations While there is no specific diet that can prevent spondylosis, a balanced, high-quality diet is essential for overall health. Some owners consider adding joint supplements, such as glucosamine and chondroitin sulfate, to their dog's diet. These supplements are thought to support cartilage health and may be beneficial for dogs with concurrent osteoarthritis. However, their efficacy for spinal conditions is not well-established, and they are not a substitute for veterinary treatment. Omega-3 fatty acids, found in fish oil, have anti-inflammatory properties and may be beneficial for dogs with chronic pain conditions. Some studies have shown that omega-3 fatty acids can reduce the need for NSAIDs in dogs with osteoarthritis. Discuss the use of supplements with your veterinarian to determine if they are appropriate for your dog. ## Special Population Considerations Spondylosis deformans can affect dogs of all breeds and sizes, but certain populations deserve special consideration. ### Large and Giant Breed Dogs Large and giant breed dogs, such as Rottweilers, German Shepherds, Great Danes, and Labrador Retrievers, are more commonly affected by spondylosis than smaller breeds [4]. This is likely due to the increased biomechanical stress on the spine associated with their larger body size. The sheer weight of these dogs places more force on the intervertebral discs and ligaments, accelerating the degenerative process. In large breed dogs, spondylosis can be particularly problematic because their size makes it more difficult for them to compensate for spinal pain. A large dog with back pain may have difficulty getting up from a lying position, may be unable to climb stairs, and may be at increased risk of falling. Weight management is especially important in these dogs, as even a small amount of excess weight can have a significant impact on spinal health. ### Working and Athletic Dogs Working dogs, such as search-and-rescue dogs, police dogs, and agility dogs, are at increased risk of developing spondylosis due to the physical demands of their work [5]. These dogs are often required to jump, climb, run, and navigate challenging terrain, all of which place significant stress on the spine. A study on search-and-rescue dogs found a high incidence of thoracic spondylosis deformans, suggesting that the physical demands of their work contribute to the condition [5]. This is an important consideration for handlers and owners of working dogs. Regular veterinary check-ups, including spinal radiographs, may be recommended for working dogs to monitor for the development of spondylosis and other spinal conditions. If a working dog is diagnosed with spondylosis, the decision to continue working must be made on an individual basis, taking into account the severity of the condition, the dog's clinical signs, and the demands of the work. In some cases, modifications to the dog's work duties may be necessary to reduce spinal stress. ### Brachycephalic Breeds Brachycephalic breeds, such as Bulldogs, Pugs, and French Bulldogs, have a unique spinal conformation that can predispose them to spinal problems. These breeds often have a condition called hemivertebrae, where the vertebrae are malformed, leading to spinal instability and an increased risk of spinal cord compression. Spondylosis can develop secondary to this instability. In brachycephalic breeds, spondylosis may be more likely to cause neurological signs due to the concurrent presence of hemivertebrae and other spinal abnormalities. Owners of these breeds should be particularly vigilant for signs of spinal pain or neurological dysfunction and should seek veterinary care promptly if any signs develop. ### Senior Dogs Spondylosis is strongly associated with aging, and the prevalence increases significantly with each year of life. In senior dogs, spondylosis is often one of several concurrent health issues, including osteoarthritis, dental disease, kidney disease, and cognitive dysfunction. The management of spondylosis in senior dogs must take into account these other conditions and the dog's overall health status. Senior dogs may be more sensitive to the side effects of medications, so the choice of pain medication must be made carefully. Regular veterinary check-ups are essential for monitoring the dog's overall health and adjusting the treatment plan as needed. ## The Role of Physical Rehabilitation Canine physical rehabilitation, also known as canine physiotherapy, is an increasingly important component of the management of spondylosis deformans. A certified canine rehabilitation therapist can design a program tailored to your dog's specific needs, with the goal of reducing pain, improving mobility, and maintaining muscle mass. ### Therapeutic Exercises Therapeutic exercises are designed to improve strength, flexibility, and coordination. They are typically performed under the guidance of a rehabilitation therapist and can be continued at home with proper instruction. - **Core strengthening exercises:** These exercises target the muscles of the abdomen, back, and pelvis, which provide support for the spine. Examples include weight shifting, sit-to-stand exercises, and balance exercises on unstable surfaces. - **Range of motion exercises:** These exercises help maintain or improve joint flexibility and can be particularly beneficial for dogs with spinal stiffness. The therapist will gently move the dog's limbs and spine through their full range of motion. - **Neuromuscular re-education:** These exercises help improve the communication between the nervous system and the muscles, which can be impaired in dogs with spinal conditions. ### Hydrotherapy Hydrotherapy, which includes swimming and underwater treadmill exercise, is an excellent form of exercise for dogs with spinal conditions. The buoyancy of the water reduces the weight-bearing load on the spine, allowing the dog to exercise with less pain and less risk of injury. The resistance of the water provides a gentle workout for the muscles, helping to maintain strength and conditioning. Underwater treadmills are particularly beneficial because they allow the therapist to control the speed and intensity of the exercise and to observe the dog's gait in a controlled environment. Swimming is also beneficial, but it is important to ensure that the dog uses a proper swimming technique to avoid excessive spinal extension. ### Manual Therapy Manual therapy, which includes massage, stretching, and joint mobilization, can be beneficial for dogs with spondylosis. Gentle massage can help relax tense muscles and improve circulation. Stretching can help maintain flexibility and reduce stiffness. Joint mobilization involves gentle, passive movement of the joints to improve their range of motion. It is crucial that manual therapy is performed by a qualified professional who understands the anatomy and biomechanics of the canine spine. Deep tissue massage or forceful stretching can exacerbate pain and cause injury, particularly in dogs with spinal instability or concurrent disc disease. ### Modalities Rehabilitation therapists may also use various modalities to manage pain and inflammation. - **Therapeutic laser (photobiomodulation):** This uses specific wavelengths of light to penetrate the tissues and promote cellular healing. It can reduce pain and inflammation and is non-invasive and painless. - **Therapeutic ultrasound:** This uses sound waves to generate heat deep within the tissues, which can help reduce pain and muscle spasm. - **Pulsed electromagnetic field therapy (PEMF):** This uses electromagnetic fields to stimulate cellular repair and reduce pain and inflammation. - **Extracorporeal shockwave therapy:** This uses high-energy sound waves to stimulate healing in musculoskeletal tissues. It has been used to treat various orthopedic conditions in dogs, although its efficacy for spondylosis specifically is not well-established. ## Long-Term Monitoring and Prognosis Spondylosis deformans is a chronic, progressive condition, and long-term monitoring is essential for maintaining your dog's quality of life. The condition is not curable, but it is manageable, and most dogs can live comfortable, happy lives with appropriate care. ### What to Expect Over Time The progression of spondylosis is highly variable. In some dogs, the bone spurs remain stable for years, causing minimal or no clinical signs. In others, the spurs continue to grow, and clinical signs may gradually worsen. It is not possible to predict the course of the condition in any individual dog. Regular veterinary check-ups, at least every six to twelve months, are recommended for dogs with spondylosis. These check-ups allow the veterinarian to assess the dog's overall health, monitor the progression of the condition, and adjust the treatment plan as needed. If your dog's clinical signs change or worsen, you should schedule a veterinary visit promptly. ### Adjusting the Treatment Plan The treatment plan for spondylosis is not static. It may need to be adjusted over time based on your dog's response to therapy and the progression of the condition. For example: - **Medication adjustments:** The dose or type of pain medication may ## Frequently Asked Questions ### 1. Is spondylosis deformans in dogs always painful? No, spondylosis deformans is not always painful and is often an incidental finding on X-rays, but it can cause pain if bone spurs impinge on nerves or lead to spinal instability. ### 2. What are the first signs of spondylosis in a dog? The first signs are often subtle and include stiffness after rest, reluctance to jump, and a decreased activity level, which can be mistaken for normal aging. ### 3. How fast does spondylosis progress in dogs? The progression of spondylosis is highly variable and typically slow, with the formation of bone spurs occurring over months to years, but the rate can differ significantly between individual dogs. ### 4. Can I give my dog over-the-counter pain medication for spondylosis? No, you should never give your dog human over-the-counter pain medications like ibuprofen or acetaminophen, as they are toxic and can be fatal; always consult your veterinarian for safe pain relief options. ### 5. What is the best treatment for spondylosis in dogs? There is no single best treatment, but a multimodal approach including weight management, controlled exercise, physical therapy, and veterinary-prescribed pain medication is most effective for managing the condition. ### 6. Can spondylosis in dogs cause hind leg weakness? Yes, in severe cases, large bone spurs can compress the spinal cord or nerve roots, leading to hind leg weakness, incoordination, or even paralysis. ### 7. Is surgery an option for dogs with spondylosis? Surgery is rarely needed and is reserved for severe cases where bone spurs cause significant spinal cord compression and medical management has failed to control the clinical signs. ### 8. What is the difference between spondylosis and intervertebral disc disease (IVDD)? Spondylosis is a bony change on the vertebrae that can cause stiffness and pain, while IVDD is a disease of the intervertebral discs that can cause severe pain and neurological deficits due to disc herniation, though they can occur together. ## Related Clinical & Scientific Guides * [Immune-Mediated Polyarthritis IMPA: Joint Pain, Fever and Steroid Protocol](/knowledge/veterinary-medicine/orthopedic-mobility/immune-mediated-polyarthritis-impa-joint-pain-fever-and-steroid-protocol) * [Hip Dysplasia in Dogs: Hip Replacement vs FHO vs Conservative Management](/knowledge/veterinary-medicine/orthopedic-mobility/hip-dysplasia-in-dogs-hip-replacement-vs-fho-vs-conservative-management) * [Thermoregulating & Heated Dog Beds: Infrared Heat Safety, Temperature Calibration, and Arthritis Relief](/knowledge/veterinary-medicine/orthopedic-mobility/heated-dog-bed-senior-arthritis)
