Why Is My Dog Pacing and Panting? Anxiety or Medical Issue?

By Dr. Zubair Khalid, DVM, MS, PhD · 2026-08-14

Key Takeaways

• Pacing and panting in dogs are critical indicators that necessitate immediate assessment, as they can signify either anxiety or serious underlying medical conditions, including life-threatening emergencies like bloat.
• Emergency signs requiring immediate veterinary intervention include a swollen/painful abdomen, retching without vomit, collapse, pale/blue gums, or severe respiratory distress, which may indicate conditions requiring surgery or oxygen support.
• Differentiating between anxiety and medical causes involves observing the duration, context, and presence of other clinical signs; persistent panting even in a cool environment, refusal to eat, limping, or signs in senior dogs with pre-existing conditions warrant a same-day veterinary appointment.
• Pain is a common, often hidden, cause of pacing and panting, and can manifest as stiffness, reluctance to move, or flinching when touched, necessitating veterinary diagnosis and treatment to avoid toxic human analgesics.
• Medical conditions such as Cushing's disease (hyperadrenocorticism), heart disease, respiratory issues, and canine cognitive dysfunction can present with pacing and panting, often requiring diagnostic bloodwork, urine analysis, or imaging for definitive diagnosis and management.
• Owners should meticulously document observations, including onset, duration, frequency, associated symptoms, and potential triggers, and consider taking video evidence to provide crucial diagnostic information to the veterinarian.

If your dog is pacing and panting, your first job is to look at the whole picture, also the behavior. Pacing means walking back and forth without settling. Panting means fast, open-mouth breathing that is not normal for your dog at rest. Together, these signs can mean your dog is anxious, in pain, or dealing with a medical condition. Some causes are minor and pass quickly. Others are serious and need urgent care.

Start by checking for emergency signs right now. If your dog is pacing and panting and also has a swollen or hard belly, is retching without producing vomit, cannot stand, has pale or blue gums, or is struggling to breathe, do not wait. Go to an emergency veterinarian immediately. These signs can point to bloat, a life-threatening stomach twist, or another crisis that requires surgery or oxygen support within minutes.

If none of those signs are present, take a slow breath and gather information. Count your dog's breaths per minute while they are standing still. Normal resting breathing for most dogs is 15 to 30 breaths per minute. Watch your dog for 15 minutes and note how often they pace, whether they can lie down at all, and what else is happening around them. This information will help you and your veterinarian decide what comes next.

Anxiety and Stress: The Most Common Cause

For many dogs, pacing and panting are the body's way of handling stress. The American College of Veterinary Behaviorists describes anxiety as a normal emotion that becomes a problem when it is intense, frequent, or out of proportion to the situation. Dogs show this through body language you can see: pacing, panting, drooling, trembling, tucked tail, flattened ears, or repeated yawning.

Common triggers include loud noises like thunder or fireworks, separation from a family member, new people or animals in the home, car rides, or changes in routine. If your dog only paces and pants during these events and settles within an hour after they end, anxiety is a strong possibility. You can help by moving your dog to a quiet room, closing curtains, playing soft background noise, and staying calm yourself. Do not punish the behavior. Punishment increases fear and makes the problem worse.

If anxiety happens often or lasts for hours, talk to your veterinarian. The AAHA Behavior Management Guidelines explain that behavior problems deserve the same careful assessment as any medical issue. Your veterinarian may recommend training, environmental changes, or medication. Dosing for any anxiety medication must come from your veterinarian, because the right amount depends on your dog's weight, health, and specific condition.

Pain: A Hidden and Common Cause

Dogs hide pain well, but pacing and panting are two of the clearest outward signs. Pain from arthritis, a dental infection, an ear problem, or an injury can make a dog restless and unable to find a comfortable position. Watch for other clues: limping, reluctance to climb stairs, flinching when touched, reduced appetite, or growling when approached.

The MSD Veterinary Manual Pet Owner Version notes that pain in dogs often appears as behavior change before it appears as obvious injury. If your dog is pacing and panting and also seems stiff or sore, book a same-day appointment. Your veterinarian can examine your dog, find the source of pain, and prescribe appropriate treatment. Never give your dog human pain medication. Many human drugs, including ibuprofen and acetaminophen, are toxic to dogs.

Medical Conditions That Cause Pacing and Panting

Several medical problems can cause these signs without any obvious trigger. One common condition is Cushing's disease, also called hyperadrenocorticism. This happens when the adrenal glands produce too much cortisol, a stress hormone. Dogs with Cushing's often drink more water, urinate more, lose hair, develop a pot belly, and pace or pant even in cool conditions. It is treatable, but diagnosis requires blood tests from your veterinarian.

Other medical causes include heart disease, which can reduce oxygen delivery and cause panting, and respiratory problems like bronchitis or collapsing trachea. Senior dogs with cognitive decline, similar to dementia, may pace and pant at night because they are confused and disoriented. The AVMA Pet Owner Resources recommend a full veterinary exam for any new or persistent behavior change, because behavior is often the first signal of internal illness.

When Pacing and Panting Happens at Night

Nighttime pacing and panting deserve special attention because they disrupt sleep for both you and your dog. If your dog is restless at night, consider whether the room is too warm, whether your dog needs to urinate more often, or whether there are new nighttime noises. Older dogs may develop a condition called canine cognitive dysfunction, which causes confusion, altered sleep cycles, and aimless pacing. This is a medical diagnosis, not a normal part of aging.

If your dog paces and pants at night for more than one or two nights, or if they also drink excessive water and urinate frequently, book a same-day appointment. These signs together can point to Cushing's disease, diabetes, or kidney problems, all of which need blood and urine testing to diagnose. The AAHA Pet Owner Resources emphasize that regular veterinary care catches these conditions earlier, when treatment is more effective.

What to Do Right Now

Write down what you observe. Note the time pacing started, how many times your dog paces per hour, whether they can settle for even five minutes, what they ate and drank, and any triggers you can identify. Take a video on your phone. Videos are extremely helpful for your veterinarian because they show the behavior exactly as it happens.

Then call your veterinarian. Describe the signs and ask whether you should come in today or go to emergency care. If your dog is eating, drinking, and using the bathroom normally, and the pacing and panting are tied to a clear trigger, you can watch at home for up to two hours. If the behavior continues beyond that, or if any emergency sign appears, seek care immediately. Your calm observation and quick action are the best tools your dog has.

What You Can Safely Do at Home Right Now

If your dog is pacing and panting but breathing normally, has pink gums, and can settle when you sit quietly with them, you can try a few things at home while you decide whether to call a vet.

First, stop and observe. Count your dog's breaths per minute while they are standing or lying still. A normal resting rate is usually between 10 and 30 breaths per minute, though panting is faster and shallower. If the rate is above 40 at rest, or if your dog is struggling to breathe, this is an emergency and you need in-person care now.

Offer water. Some dogs pace because they are thirsty or overheated. Put a bowl down and watch them drink. Do not force water into their mouth.

Move to a calm, cool space. Turn off loud noises, dim bright lights, and keep other pets or children away. A quiet room with a fan or air conditioning can help if heat is a factor. Sit on the floor and speak softly. Some anxious dogs settle when you model calm behavior, but do not restrain, hug, or force your dog to lie down. That can raise their stress.

Do not give any medication, including over-the-counter human drugs like diphenhydramine (Benadryl), aspirin, or melatonin, unless your veterinarian has specifically prescribed it for this dog at this time. Human doses are not safe to guess, and some drugs make medical conditions worse. Your vet must determine the correct drug and dose based on your dog's weight, health, and the cause of the signs.

Do not try to make your dog vomit. Do not give food if you suspect a blockage or bloat. Do not put your dog in a crate if they are restless, as this can worsen panic or overheating.

What to Write Down Before You Call the Vet

A clear history speeds up diagnosis. Before you call, write down:

• When the pacing started and how long it has lasted
• How many times per hour your dog paces or circles
• Whether panting is constant or comes in waves
• Your dog's age, breed, and whether they are spayed or neutered
• Any recent changes in food, routine, travel, or household members
• Any other signs: vomiting, diarrhea, drooling, limping, whining, hiding, or loss of appetite
• Whether your dog can sleep at all, and how often they wake at night
• Any medications or supplements your dog takes, with doses and times

Take a short video of the behavior. Video is often more useful than a verbal description, because it shows the exact pattern of pacing, posture, and breathing.

What a Veterinary Visit Usually Involves

Your vet will start with the history you wrote down, then perform a full physical exam. They will feel your dog's abdomen, listen to the heart and lungs, check the gums, take a temperature, and watch your dog move. This hands-on exam is essential. Pacing and panting can come from the heart, lungs, brain, hormones, joints, or stomach, and a vet needs to narrow that down.

Depending on findings, your vet may recommend bloodwork, urine testing, X-rays, or an ultrasound. Bloodwork can check for Cushing's disease, thyroid problems, kidney or liver disease, and infection. X-rays can reveal heart enlargement, lung issues, or a foreign body. If anxiety is suspected, your vet may refer you to a veterinary behaviorist, who specializes in behavior disorders and their medical causes. The American College of Veterinary Behaviorists offers resources on how anxiety is diagnosed and treated, and the American Animal Hospital Association publishes behavior management guidelines that many vets follow.

Cost varies widely by region and clinic. A basic exam with bloodwork typically ranges from $150 to $500. Advanced imaging or specialist referral can push that higher, sometimes over $1,000. These are general ranges only, not quotes. Your clinic can give you an estimate before testing. Ask what each test is for and what it will change about treatment.

When an Online Vet Can Help, and When It Cannot

Some situations in this article require hands-on care and must not be handled remotely. If your dog has pale gums, difficulty breathing, collapse, a swollen or painful belly, repeated vomiting, or signs of heatstroke, do not use a video call. Go to an emergency clinic now. Bloat, heart failure, and heatstroke can kill within hours, and no remote consultation can replace a physical exam in those cases.

A remote consultation is genuinely useful in other situations. If your dog has mild, short-lived pacing after a stressful event, if you are rechecking a known anxiety problem, or if you are unsure whether a sign warrants a visit, an online vet can help you decide. They can also answer medication side effect questions or follow up on a chronic condition like Cushing's disease.

A remote vet can take a history, watch your dog on video, and advise you. In many states they can prescribe, but rules differ, and some require an in-person exam first. What they cannot do is palpate the abdomen, listen to the chest, take a temperature, run bloodwork, or image anything. If your dog needs any of those, the online vet should tell you to come in. Use remote care as a triage tool, not a substitute for diagnosis when the cause is unknown. The American Veterinary Medical Association and the American Animal Hospital Association both provide guidance on working with your veterinarian and knowing when a visit is needed.

Common Mistakes Owners Make With Pacing and Panting

When your dog paces and pants, it is easy to fall into patterns that delay help or make things worse. Here are the most common mistakes and what to do instead.

The biggest mistake is guessing. You cannot tell anxiety from pain or heart disease by watching alone. A veterinarian can. If you are unsure, call your clinic and describe what you see. They can tell you whether to come in now or monitor at home.

How to Reduce the Chance of It Happening Again

Once your vet has ruled out medical causes, you can work on prevention. Anxiety-related pacing often responds to routine. Feed, walk, and play at the same times each day. Dogs find comfort in predictability.

Create a calm space. A quiet room with a comfortable bed, soft lighting, and familiar toys can help an anxious dog settle. Some dogs do well with background noise like a fan or gentle music. The American College of Veterinary Behaviorists offers resources on behavior modification for anxiety disorders.

Exercise matters, but timing matters more. A tired dog is calmer, yet intense exercise right before bed can cause restlessness. Aim for a moderate walk earlier in the evening, then a short, calm potty break before bed.

For dogs with separation anxiety or noise phobias, gradual desensitization can help. This means exposing the dog to the trigger at a very low level and rewarding calm behavior. Work with a certified trainer or veterinary behaviorist. The AAHA Behavior Management Guidelines describe how structured behavior plans are built.

If the cause is medical, prevention means managing the condition. Pain from arthritis needs ongoing treatment. Cushing's disease needs regular medication and monitoring. Follow your vet's follow-up schedule. Do not skip blood tests or rechecks.

What Recovery and Ongoing Management Usually Look Like

Recovery time depends entirely on the cause. There is no single timeline.

For anxiety, you may see improvement within days once you change the routine and environment. Full behavior modification often takes weeks or months. Be patient. Small progress counts.

For pain, expect improvement within a few days of starting pain relief. If your dog does not improve within a week, tell your vet. The dose may need adjustment, or the diagnosis may need revisiting.

For Cushing's disease, treatment is lifelong. Most dogs show reduced panting and pacing within a few weeks of starting medication. Regular blood tests are needed to adjust the dose. The MSD Veterinary Manual Pet Owner Version explains that Cushing's is managed, not cured.

For cognitive dysfunction, which is like dog dementia, management focuses on slowing progression. Some dogs improve with medication and environmental enrichment. Others hold steady for months. The goal is quality of life, not a cure.

Throughout management, keep a log. Write down how often your dog paces, when it happens, and what helps. Bring this log to every vet visit. It gives your vet concrete data to adjust treatment.

Frequently Asked Questions

My dog paces and pants after exercise. Is that normal?

Yes, within reason. After vigorous exercise, dogs pant to cool down. Pacing for a few minutes while they catch their breath is normal. But if the pacing continues for more than 15 minutes, or if your dog seems distressed, call your vet. Overheating and heart problems can look like normal post-exercise panting at first.

Can I give my dog Benadryl to calm them down?

No. Benadryl is not a reliable anti-anxiety medication for dogs, and the correct dose depends on your dog's weight and health. Giving the wrong dose can cause sedation, agitation, or more serious side effects. Some dogs have reactions to it. Call your veterinarian for a safe, effective option.

How do I know if my dog is in pain versus anxious?

Pain often comes with other signs: limping, flinching when touched, reduced appetite, or a change in posture. Anxious dogs may also pace, but they often respond to your presence or a calming routine. The only reliable way to tell is a veterinary examination. Do not try to diagnose this at home.

My dog only paces at night. Should I worry?

Nighttime pacing can be normal in older dogs with cognitive decline, but it can also signal pain, Cushing's disease, or a need to urinate more often. If your dog also drinks a lot of water, loses house training, or seems confused, call your vet. If the dog is retching, drooling, or has a swollen belly, go to an emergency vet immediately.

How long should I wait before calling the vet?

If your dog has been pacing and panting for more than an hour without stopping, call your vet. If there are any emergency signs like collapse, difficulty breathing, pale gums, or a hard abdomen, do not wait. Go to an emergency clinic now. When in doubt, call. Veterinary teams are used to these questions.

Will my dog need medication forever?

Not necessarily. If the cause is anxiety, medication may be temporary while you work on behavior modification. If the cause is pain or a hormonal condition like Cushing's, medication is often lifelong. Your vet will explain the plan and adjust it over time. Regular rechecks help determine what your dog needs long term.
