# Saint Bernard Health Problems: Entropion Ectropion and Hip Joint Disease
## Key Takeaways
- Saint Bernards are predisposed to entropion (eyelid rolling inward) and ectropion (eyelid rolling outward) due to their loose facial skin and conformation, leading to corneal irritation and inflammation. Diagnosis involves physical examination, and definitive treatment for entropion is surgical blepharoplasty, while ectropion may be managed medically or surgically.
- Hip dysplasia (HD) is a developmental, hereditary condition in Saint Bernards characterized by abnormal hip joint development, leading to laxity and subsequent osteoarthritis. Diagnosis relies on physical orthopedic examination (e.g., Ortolani test) and radiographic evaluation (OFA or PennHIP).
- Clinical signs of hip dysplasia include hind-limb lameness, a "bunny-hopping" gait, and reluctance to rise, typically appearing between 4-12 months of age, though osteoarthritis signs may manifest later. Management is multimodal, focusing on weight control, controlled low-impact exercise, NSAIDs for pain, and potentially joint supplements.
- Surgical interventions for hip dysplasia include Juvenile Pubic Symphysiodesis (JPS) for young puppies, Triple Pelvic Osteotomy (TPO), and Total Hip Replacement (THR) for end-stage disease, with THR offering excellent functional restoration.
- Preventative measures for hip dysplasia include responsible breeding practices (screening parents via OFA/PennHIP) and managing environmental factors in puppies, such as controlled growth rate, appropriate nutrition (avoiding excessive calories/calcium), and avoiding high-impact exercise.
- Prompt veterinary attention is critical for eye conditions like entropion/ectropion, as corneal ulcers can rapidly lead to vision loss; for hip disease, early intervention and lifelong management are key to maintaining mobility and quality of life.

The Saint Bernard is a giant breed known for its gentle temperament and historical role as an alpine rescue [dog](/knowledge/veterinary-medicine/clinical-methods/dog). However, their distinctive conformation, particularly their loose skin and heavy bone structure, predisposes them to specific health challenges. The most common issues owners face involve the eyelids (entropion and ectropion) and the hip joints (hip dysplasia and osteoarthritis). This article provides a definitive, source-grounded overview of these conditions, covering everything from early signs to surgical and medical management.
**Owner Triage Summary:** If your Saint Bernard is squinting, has excessive tearing, or you can see the eyelid rolling inward, this is an emergency for their eye health and requires veterinary attention within 24 hours. If your dog is showing hind-end weakness, a "bunny-hopping" gait, or difficulty rising, schedule a veterinary orthopedic exam. Early intervention is critical for both pain management and long-term mobility.

## Understanding the Anatomy and Physiology
To understand these diseases, one must first appreciate the anatomy of the eye and the hip.
### The Eyelids and Ocular Surface
The eyelids are complex structures that protect the globe, distribute tears, and remove debris. The margin of the eyelid is where the skin meets the conjunctiva (the mucous membrane lining the inside of the eyelid and the eyeball). In a healthy dog, the eyelid margin rests gently against the cornea, allowing the eyelashes (cilia) to point away from the eye. The "third eyelid" (nictitating membrane) provides additional protection and produces a significant portion of the tear film.
The tear film has three layers: an outer lipid (oily) layer, a middle aqueous (watery) layer, and an inner mucin (mucous) layer. This film is essential for corneal health, providing lubrication, nutrients, and antimicrobial proteins. Any conformational abnormality, such as entropion or ectropion, disrupts this delicate system, leading to corneal damage or chronic inflammation.
### The Hip Joint and Its Development
The hip is a ball-and-socket joint. The "ball" is the head of the femur (thigh bone), and the "socket" is the acetabulum, a cup-shaped structure in the pelvis. In a normal joint, the femoral head fits snugly into the acetabulum, held in place by a strong joint capsule, a ligament (the round ligament), and surrounding muscles.
Hip dysplasia is a developmental disease where the joint develops abnormally. This can range from a shallow acetabulum to a loose joint capsule. The resulting laxity (looseness) allows the femoral head to move excessively within the joint. This abnormal motion causes micro-trauma to the cartilage, leading to inflammation, pain, and the eventual development of osteoarthritis (degenerative joint disease). The body attempts to stabilize the joint by laying down new bone (bone spurs or osteophytes), which further restricts movement and causes chronic pain.
## Entropion: The Inward-Rolling Eyelid
Entropion is a condition where the eyelid margin rolls inward toward the eye. This causes the eyelashes and facial hair to rub against the cornea and conjunctiva, leading to significant pain, corneal ulceration, and potentially vision loss. In the Saint Bernard, entropion most commonly affects the lower eyelids, though the upper lids can also be involved.
### Causes and Predisposition
The primary cause of entropion in the Saint Bernard is genetic. The breed's characteristic facial conformation, with loose skin and a heavy brow, creates tension that pulls the eyelids inward. This is often termed "anatomical" or "conformational" entropion. The condition is considered hereditary, and affected dogs should not be bred. While the exact genetic markers are not fully understood, it is a well-recognized breed-specific issue.
### Clinical Signs and Diagnosis
Owners may notice their Saint Bernard squinting (blepharospasm), rubbing at their eyes, or having excessive tearing (epiphora). The eye may appear red and inflamed. A thick, mucoid discharge may also be present.
Diagnosis is made via a thorough ophthalmic examination. A veterinarian will:
1. **Observe the eyelid conformation:** They will assess the angle of the eyelid margin.
2. **Perform a Schirmer Tear Test (STT):** This measures tear production to rule out keratoconjunctivitis sicca (dry eye), which can cause similar signs.
3. **Apply a fluorescein stain:** This green dye adheres to damaged corneal tissue, revealing any ulcers or erosions caused by the hair rubbing against the eye. This is a critical step, as corneal ulcers can progress rapidly.
### Evidence-Based Management and Treatment
The definitive treatment for entropion is surgery to correct the eyelid position. This procedure, known as a blepharoplasty, involves removing a small wedge of skin from the affected eyelid and suturing the edges together, effectively pulling the eyelid outward into its normal position.
- **Pre-Surgical Management:** While waiting for surgery, or if the condition is mild, the veterinarian may prescribe topical lubricants (artificial tears) and antibiotic or anti-inflammatory eye drops to protect the cornea and manage secondary infection. An Elizabethan collar (e-collar) is essential to prevent self-trauma from rubbing.
- **Surgical Techniques:** Several techniques exist, including the "Hotz-Celsus" procedure, which is the most common for entropion. In severe cases or in young puppies, a temporary "tacking" procedure may be performed. This involves placing temporary sutures to evert the eyelid, allowing the face to grow and mature before a permanent correction is done. This is often recommended for puppies under 6 months of age to allow for facial growth, as a premature permanent surgery may lead to over-correction later.
- **Post-Operative Care:** After surgery, the dog must wear an e-collar to prevent rubbing. Oral pain medication and topical antibiotics are typically prescribed. Sutures are usually removed 10-14 days post-operatively.
**Prognosis:** The prognosis for entropion is excellent with prompt and appropriate surgical correction. Early intervention prevents chronic corneal damage, which can lead to scarring and vision impairment.
## Ectropion: The Outward-Rolling Eyelid
Ectropion is the opposite of entropion; the eyelid margin rolls outward, away from the eye. This exposes the delicate conjunctiva (the pink tissue lining the inside of the eyelid) to the environment, leading to chronic dryness, irritation, and inflammation.
### Causes and Predisposition
Like entropion, ectropion in the Saint Bernard is primarily a conformational or genetic condition. The breed's loose facial skin and heavy jowls cause the lower eyelids to sag and droop. This is often seen in conjunction with entropion, a condition sometimes referred to as "diamond eye" or macroblepharon, where the eyelid opening is too large for the eye.
### Clinical Signs and Diagnosis
The most obvious sign is a drooping lower eyelid that exposes the red, inflamed conjunctiva. Owners may notice a mucoid or mucopurulent (pus-like) discharge in the corner of the eye. The dog may not show obvious signs of pain, unlike with entropion, but the chronic exposure can lead to conjunctivitis and, in severe cases, keratitis (inflammation of the cornea).
Diagnosis is straightforward based on physical examination. A fluorescein stain is still important to check for corneal ulcers, which can develop if the dog rubs its eye or if a foreign body becomes trapped in the exposed conjunctival sac.
### Evidence-Based Management and Treatment
Management depends on the severity of the condition.
- **Medical Management:** For mild cases, the primary goal is to keep the eye lubricated and clean. Veterinarians may prescribe artificial tear solutions or ointments to be applied regularly. If a secondary bacterial infection is present, topical antibiotics are indicated. Regular cleaning of the facial folds and the eye area is essential to prevent skin irritation and infection.
- **Surgical Management:** Surgery is considered when medical management fails to control clinical signs, or if the ectropion is severe enough to cause chronic, painful conjunctivitis or keratitis. The surgical procedure is a form of blepharoplasty, but instead of removing a wedge of skin, the surgeon shortens the eyelid by removing a section from the outer corner (lateral canthus) or performs a wedge resection to tighten the eyelid margin.
**Prognosis:** The prognosis for ectropion is generally good. Many dogs live comfortably with medical management. For those requiring surgery, the outcome is often excellent, with significant improvement in comfort and a reduction in discharge.
## Hip Joint Disease: From Dysplasia to Osteoarthritis
Hip joint disease in the Saint Bernard encompasses a spectrum of conditions, most commonly starting with hip dysplasia (HD) and progressing to osteoarthritis (OA). This is a leading cause of pain and disability in this breed.
### Causes and Risk Factors
Hip dysplasia is a polygenic, heritable disease, meaning multiple genes contribute to its development. Environmental factors play a significant role in how the genetic predisposition manifests.
- **Genetics:** The condition is strongly inherited. Breeding dogs with good hip scores (e.g., OFA Excellent or Good) reduces the risk in offspring.
- **Growth Rate:** Rapid growth and excessive caloric intake during puppyhood can exacerbate the development of HD. Overweight puppies are at significantly higher risk.
- **Exercise:** High-impact exercise (e.g., jumping, rough play) on developing joints can worsen the condition. Conversely, controlled, low-impact exercise is beneficial.
- **Nutrition:** Diets that are too high in calcium or calories can disrupt normal skeletal development in large-breed puppies.
### Clinical Signs and Diagnosis
The signs of HD can appear as early as 4-6 months of age, or they may not become apparent until later in life when osteoarthritis is already established.
**Common signs in puppies and young adults:**
- Hind-limb lameness, especially after exercise.
- "Bunny-hopping" gait (moving both hind legs together).
- Reluctance to run, jump, or climb stairs.
- Difficulty rising from a lying or sitting position.
- Pain on extension or manipulation of the hip joint.
**Common signs in older dogs (osteoarthritis):**
- Stiffness, especially after rest.
- Decreased activity and reluctance to play.
- Muscle atrophy (wasting) in the hind limbs.
- Audible clicking or grinding sounds in the joint.
- Changes in behavior, such as irritability or aggression.
**Diagnosis** is based on a combination of physical examination and diagnostic imaging.
1. **Orthopedic Examination:** The veterinarian will manipulate the hips to assess for pain, crepitus (grinding sensation), and range of motion. Specific tests, such as the Ortolani test, are used to detect joint laxity in young dogs.
2. **Radiographs (X-rays):** This is the gold standard for diagnosis. Two main evaluation schemes are used:
- **OFA (Orthopedic Foundation for Animals):** Requires a specific hip-extended view, typically performed after 2 years of age. It grades hips as Excellent, Good, Fair, Borderline, or Dysplastic.
- **PennHIP (University of Pennsylvania Hip Improvement Program):** This method measures joint laxity using a distraction index (DI). It can be performed as early as 16 weeks of age and is a more sensitive predictor of future osteoarthritis than the OFA view.
### Evidence-Based Management and Treatment
The management of hip joint disease is multimodal, meaning it combines several treatment strategies. The goal is to reduce pain, improve function, and slow the progression of osteoarthritis.
#### Non-Surgical (Medical) Management
This is the mainstay of treatment for many dogs, especially those with mild to moderate disease.
- **Weight Management:** This is the single most important factor. Maintaining a lean body condition score dramatically reduces stress on the joints. A study on the impact of obesity on lifespan and joint disease, while focused on human health, highlights the systemic impact of excess weight on joint health and longevity [1][2]. The same principle applies to dogs; every extra pound of fat translates to increased force on the hip joint.
- **Physical Therapy and Exercise:** Controlled, low-impact exercise is crucial. This includes leash walks, swimming, and underwater treadmill therapy. These activities strengthen the muscles that support the joint without causing high-impact stress. Avoid activities like fetch, jumping, and rough play.
- **Pain Management (NSAIDs):** Non-steroidal anti-inflammatory drugs (NSAIDs) are the cornerstone of pain relief for osteoarthritis. These medications (e.g., carprofen, meloxicam, grapiprant) reduce inflammation and pain. They must be used under the strict supervision of a veterinarian, as they can have side effects on the kidneys, liver, and gastrointestinal tract. Routine blood work is recommended to monitor organ function.
- **Disease-Modifying Osteoarthritis Agents (DMOAAs):** These include supplements like glucosamine, chondroitin sulfate, and omega-3 fatty acids. While evidence for their efficacy is variable, they are often used as part of a comprehensive plan to support cartilage health. Omega-3 fatty acids have the strongest evidence for reducing inflammation.
- **Regenerative Medicine:** Therapies such as stem cell therapy and platelet-rich plasma (PRP) are becoming more common. These treatments aim to reduce inflammation and promote tissue repair. While promising, they are not a cure and their long-term efficacy is still being investigated.
- **Assistive Devices:** Items like orthopedic beds, ramps, and rear-support slings can significantly improve a dog's quality of life by making it easier to rest and move around.
#### Surgical Management
Surgery is considered when medical management fails to control pain, or in young dogs with severe laxity.
- **Juvenile Pubic Symphysiodesis (JPS):** This is a minimally invasive procedure performed on puppies between 16 and 20 weeks of age. It involves using electrocautery to fuse the pubic symphysis (the joint at the bottom of the pelvis). This alters the growth of the pelvis, causing the acetabulum to rotate and provide better coverage of the femoral head. It is most effective in dogs with mild to moderate laxity and no existing osteoarthritis.
- **Triple Pelvic Osteotomy (TPO):** This is a more involved surgery for young dogs (typically under 10-12 months) with no or minimal osteoarthritis. It involves cutting the pelvis in three places and rotating the acetabulum to improve femoral head coverage.
- **Total Hip Replacement (THR):** This is the gold-standard surgical treatment for end-stage hip disease. It involves replacing the entire hip joint with a prosthetic ball and socket. THR provides excellent pain relief and restores near-normal function. It is a major surgery but has a very high success rate in appropriate candidates.
- **Femoral Head and Neck Excision (FHNE):** This is a salvage procedure where the head and neck of the femur are surgically removed, creating a "false joint" made of scar tissue. It is less expensive than THR and is an option for dogs where THR is not feasible. The outcome is variable, with smaller, leaner dogs often having better results than large, heavy dogs.
**Prognosis:** The prognosis for hip dysplasia is highly variable. With early diagnosis, aggressive weight management, and a comprehensive medical plan, many dogs can live comfortable, active lives. For dogs that do not respond to medical therapy, surgical options like THR can provide a dramatic improvement in quality of life.
## Unsafe Home Remedies and What to Avoid
Owners often want to help their pets at home, but some common practices are harmful.
- **Never give human NSAIDs:** Medications like ibuprofen, naproxen, and aspirin are highly toxic to dogs and can cause severe stomach ulcers, kidney failure, and even death. Always use veterinary-prescribed medications.
- **Do not attempt to pop or drain eye lesions:** If you see a red, swollen mass or a cloudy eye, do not attempt to treat it at home. This could be a corneal ulcer or a prolapsed gland, requiring immediate veterinary care.
- **Avoid unregulated joint supplements:** Not all supplements are created equal. Some may not contain the labeled ingredients. Choose products that have been independently tested for quality.
- **Do not force exercise:** If your dog is lame or in pain, do not force them to go for a walk or "run it off." Rest is essential for acute flare-ups. Pushing a dog with hip pain can cause further joint damage.
## Prevention and Breeding Considerations
Prevention is the most effective strategy for managing breed-specific health problems.
- **For Hip Dysplasia:** The most critical step is responsible breeding. Dogs should be screened for HD via OFA or PennHIP before being bred. Breeding only dogs with excellent hip conformation significantly reduces the incidence of the disease. For individual owners, the focus is on prevention through nutrition and exercise. Feed a high-quality, large-breed puppy food that is not overly high in calories or calcium. Avoid free-feeding and keep your puppy lean. Controlled exercise on soft surfaces is ideal.
- **For Entropion/Ectropion:** These conditions are also hereditary. Affected dogs should not be bred. Breeders should select for dogs with correct eyelid conformation. There is no known way to prevent these conditions in an individual dog beyond responsible breeding.
## Prognosis and Long-Term Care
- **For Eye Conditions:** With prompt surgical correction of entropion, the prognosis is excellent, and the dog can have normal vision and comfort for life. Ectropion is often manageable with medication, and surgery is successful in severe cases. Regular veterinary eye exams are important to monitor for recurrence or complications.
- **For Hip Disease:** The prognosis is a lifelong commitment to management. Osteoarthritis is a progressive disease, meaning it will worsen over time. However, with a dedicated owner and a good veterinary team, the progression can be slowed, and pain can be managed effectively. The goal is to maintain a good quality of life, not to cure the disease. Regular check-ups, weight monitoring, and adjustments to the treatment plan are essential.
## Limitations and When to Contact a Veterinarian
This article provides a comprehensive overview of common Saint Bernard health problems, but it has limitations. Breed-level information cannot predict what will happen to an individual dog. The severity of these conditions varies widely, and each dog's response to treatment is unique. This information is educational and is not a substitute for veterinary diagnosis or treatment.
**Contact your veterinarian immediately if you notice any of the following:**
- **Eye:** Squinting, excessive tearing, a cloudy or bluish cornea, visible ulcers, or if your dog is rubbing at their eye. Eye problems can progress to vision loss very quickly.
- **Hip:** Sudden inability to walk, severe lameness, or signs of extreme pain (whining, panting, trembling). If your dog is dragging their hind legs, this is an emergency.
- **General:** Any change in appetite, behavior, or activity level. Vomiting or diarrhea (or diarrhoea) that lasts more than 24 hours, especially in a puppy or senior dog, warrants a vet visit.
## Frequently Asked Questions
### 1. At what age do Saint Bernards typically show signs of hip dysplasia?
Signs of hip dysplasia can appear as early as 4 to 6 months of age. Puppies may show a "bunny-hopping" gait, reluctance to exercise, or difficulty rising. However, some dogs do not show clinical signs until they are older and osteoarthritis has developed.
### 2. Can entropion be fixed without surgery?
No, surgery is the only definitive treatment for entropion. While medical therapy like lubricating eye drops can protect the cornea temporarily, the underlying conformational abnormality (the eyelid rolling inward) requires surgical correction to prevent ongoing damage.
### 3. What is the difference between entropion and ectropion?
Entropion is the inward rolling of the eyelid, causing hair to rub against the eye. Ectropion is the outward rolling or sagging of the eyelid, exposing the inner conjunctiva. Both are common in Saint Bernards and are often seen together.
### 4. Is hip dysplasia in Saint Bernards hereditary?
Yes, hip dysplasia is a polygenic, hereditary disease. This means it is passed down from parents to offspring through multiple genes. Environmental factors like rapid growth and obesity can also influence the severity of the disease.
### 5. What is the best diet for a Saint Bernard with hip problems?
The best diet is one that maintains a lean body condition. A high-quality, large-breed adult formula is often recommended. Your veterinarian may also recommend a diet supplemented with omega-3 fatty acids and glucosamine/chondroitin to support joint health. Avoid overfeeding.
### 6. Is total hip replacement (THR) a safe option for a giant breed dog?
Yes, total hip replacement is considered the gold standard for treating end-stage hip dysplasia in dogs, including giant breeds like the Saint Bernard. It has a very high success rate and provides excellent long-term pain relief, but it is a major surgery requiring a skilled surgeon and dedicated aftercare.
### 7. How can I prevent my Saint Bernard puppy from developing hip dysplasia?
You cannot change their genetics, but you can manage environmental risk factors. Keep your puppy lean, feed a controlled-calorie large-breed puppy food, and avoid high-impact activities like jumping and rough play until their growth plates close (around 12-18 months). Encourage controlled, low-impact exercise like leash walks and swimming.
### 8. What does a corneal ulcer look like in a dog?
A corneal ulcer may appear as a cloudy, opaque, or bluish area on the surface of the eye. The eye is often red and painful, and the dog may squint or have excessive tearing. It is a medical emergency that requires immediate veterinary attention.
