How to Perform CPR on a Dog: Step-by-Step Guide

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

Key Takeaways

• Cardiopulmonary resuscitation (CPR) for dogs is indicated only in cases of unconsciousness, absence of spontaneous respiration, and no palpable pulse, typically confirmed by checking the inner thigh or behind the elbow for a pulse for no more than 10 seconds.
• The primary objective of CPR is to manually circulate oxygenated blood to vital organs, particularly the brain, until advanced veterinary intervention can be initiated; it does not typically restart the heart.
• Dog CPR technique varies by size and chest shape, involving chest compressions at a rate of 100-120 per minute to a depth of one-third to one-half of chest width, followed by two rescue breaths delivered into the nose with the muzzle sealed.
• A critical component of effective CPR is minimizing interruptions; compressions should be continuous with brief pauses only for rescue breaths, and pulse checks should not be performed more frequently than every two minutes to maintain blood flow.
• Common errors include compressing too slowly or too fast, prolonged pauses for pulse checks, incorrect hand placement, and performing human CPR techniques; hands-only CPR is a viable alternative if rescue breaths are not feasible due to disease transmission concerns.
• CPR should be continued until the dog regains spontaneous breathing and pulse, a veterinary team takes over, or the rescuer is physically unable to continue; prolonged efforts (e.g., over 20 minutes) with no response significantly decrease the likelihood of survival, but the decision to cease should ideally be made in consultation with a veterinarian.

If your dog has collapsed, is not breathing, or has no heartbeat, start CPR immediately and have someone call the nearest emergency veterinary hospital. Do not wait to see if your dog improves on their own. Every second without oxygenated blood reaching the brain reduces the chance of survival. If you are alone, perform CPR for two minutes, then call the emergency vet while continuing compressions if you can do so hands-free. If your dog is breathing but unconscious, do not perform CPR. Instead, keep them warm, check their airway, and transport them to an emergency vet right away.

CPR stands for cardiopulmonary resuscitation. It combines chest compressions to pump blood and rescue breaths to deliver oxygen. Dog CPR is different from human CPR in important ways, and the technique depends on your dog's size and chest shape. This guide gives you the steps, but it cannot replace hands-on training or immediate veterinary care. Your goal is to keep blood moving until a veterinarian can take over.

If you are unsure whether your dog is breathing, place your hand in front of their nostrils for 10 seconds. Watch their chest rise and fall. A dog in cardiac arrest will be completely still and unresponsive to their name or a gentle touch.

What Is Happening in Cardiac Arrest

Cardiac arrest means the heart has stopped pumping blood effectively. The brain and other organs are starved of oxygen. Without intervention, brain damage begins within minutes. CPR does not restart the heart in most cases. Its purpose is to manually circulate blood until the heart can be shocked or treated by a veterinarian. Many dogs in cardiac arrest have an underlying cause such as severe trauma, poisoning, heart disease, or a blocked airway. You may never know the cause at the moment, and that is okay. Your job is to act.

What Else Could This Be?

Not every collapse means cardiac arrest. A dog that is unconscious but still breathing may have low blood sugar, a seizure, heatstroke, or a sudden drop in blood pressure. A dog that is gasping may be in respiratory distress from fluid in the lungs, a foreign object in the airway, or a collapsed windpipe. These conditions need emergency veterinary care, but they do not require chest compressions. Performing CPR on a dog with a beating heart can cause rib fractures or internal injury. Always check for breathing and a pulse before starting compressions.

To check for a pulse, place two fingers on the inside of the upper thigh where the leg meets the body. Press gently until you feel a rhythmic beat. You can also feel for a pulse on the chest wall just behind the elbow. If you cannot find a pulse within 10 seconds, begin CPR.

When to Start CPR

Start CPR only when all three are true: your dog is unconscious, not breathing, and has no detectable pulse. If your dog is unconscious and not breathing but you cannot find a pulse, start CPR. If you find a pulse but there is no breathing, give rescue breaths only and transport immediately. Do not perform chest compressions on a dog with a pulse.

When to Stop CPR

Continue CPR until one of these happens: your dog starts breathing on their own, a pulse returns, a veterinary team takes over, or you are physically unable to continue. Do not stop after one or two minutes to "see if it worked." Effective CPR is exhausting, and you may need to rotate with another person if available. If you have been performing CPR for 20 minutes with no response, the likelihood of recovery is very low, but the final decision to stop belongs to you and the veterinarian. Some owners choose to continue until they reach the hospital. That is a reasonable choice.

Before You Begin: Position and Airway

Lay your dog on their right side on a firm, flat surface. A table, the floor, or a hard board works. Carpet is acceptable if nothing else is available. Open the mouth and pull the tongue forward. Look inside for vomit, blood, or foreign objects. If you see something, sweep it out with your finger. Do not push it deeper. Extend the head and neck gently to open the airway. For brachycephalic breeds, dogs with flat faces like pugs and bulldogs, the airway is naturally narrow, so this step matters even more.

The American Veterinary Medical Association provides general guidance on pet emergencies and working with your veterinarian, which can help you prepare for urgent situations before they happen. You can find that resource at the AVMA Pet Owner Resources page. The MSD Veterinary Manual Pet Owner Version also explains emergency signs and first aid in plain language.

Step-by-Step CPR for Your Dog

CPR combines chest compressions with rescue breathing. It keeps blood moving to the brain and heart until the heart can restart on its own or until a veterinarian can take over. Do not start CPR unless the dog is truly unresponsive and not breathing normally. If you are unsure, check for 10 seconds. Look for chest movement, feel for breath on your cheek, and watch for any response to your voice or a gentle touch. If there is no breathing and no response, begin CPR immediately.

Step 1: Position the Dog

Place the dog on a firm, flat surface. A table, a hard floor, or a yoga mat on the ground all work. Do not use a bed or sofa, the surface must be solid for compressions to be effective. For most dogs, lay them on their right side. This position lets you access the heart most easily. For dogs with a deep chest, like a Greyhound or Boxer, the heart sits lower in the chest. For barrel-chested dogs, like a Bulldog, the heart sits higher. If you are unsure, aim for the widest part of the chest, just behind the elbows.

Step 2: Find the Compression Point

The heart sits in the lower half of the chest, just behind the elbows. Place your hand on the dog's side, right where the elbow meets the chest wall when the leg is bent back. For a small dog under 30 pounds, you can use one hand. Place your thumb on one side of the chest and your fingers on the other side, and squeeze the chest between them. For a larger dog, place the heel of one hand on the chest, then place your other hand on top. Keep your elbows straight and use your body weight to push down.

Step 3: Give Chest Compressions

Push straight down. The goal is to compress the chest by about one-third to one-half of its width. For a small dog, that might be less than an inch. For a large dog, it could be two to three inches. Let the chest fully recoil between compressions. Do not lean on the chest, you must allow it to expand again. Aim for a rate of 100 to 120 compressions per minute. That is roughly two compressions per second. You can count aloud, "one and two and three and four," to keep a steady rhythm. If you have a song in your head that matches that tempo, use it to pace yourself.

Step 4: Give Rescue Breaths

After every 30 compressions, stop and give two rescue breaths. Tilt the dog's head back slightly to open the airway. Hold the muzzle closed with one hand, making sure the lips are sealed over the teeth. Place your mouth over the dog's nose. Blow gently until you see the chest rise. Do not blow hard, you are filling the lungs, not inflating a balloon. Give two breaths, each lasting about one second. Watch the chest fall between breaths. If the chest does not rise, reposition the head and try again. Then return to compressions immediately.

Step 5: Continue Without Stopping

Keep the cycle going: 30 compressions, then two breaths. Do not stop to check for a pulse or breathing more often than every two minutes. Stopping too often reduces blood flow to the brain. If a second person is present, take turns every two minutes so neither of you becomes too tired to compress effectively. Switch positions smoothly, without pausing the compressions for more than a few seconds.

What to Measure and Write Down

If you can, have someone else call the nearest emergency veterinary clinic while you perform CPR. That person should tell the clinic your dog's breed, approximate weight, and what happened before the collapse. They should also note the time CPR started. If you are alone, perform CPR for two minutes, then call the clinic. Do not stop compressions for longer than 10 seconds to make the call.

Write down anything you observed in the minutes before collapse. Did the dog vomit? Did it have a seizure? Did it eat something unusual? Did it collapse during exercise or while resting? This information helps the veterinarian choose the right next steps. Do not give your dog anything by mouth, including water, while it is unconscious. The dog cannot swallow safely, and fluid can enter the lungs.

What a Veterinary Visit Involves

When you arrive at the emergency clinic, the team will take over CPR if your dog is still not breathing. They may place an intravenous catheter to deliver medications directly into the bloodstream. They will likely use an electrocardiogram, or ECG, to see the heart's electrical activity. This tells them whether the heart is in a rhythm that can respond to medication or a shock. They may also give oxygen, check blood gases, and look for underlying causes such as toxins, trauma, or heart disease.

The veterinarian will ask you the same questions you wrote down. They will want to know how long CPR was performed at home and whether the dog ever regained consciousness. Be honest about what you saw. This information guides their decisions about continuing or stopping resuscitation.

The cost of an emergency visit and CPR attempt varies widely. A basic emergency examination and oxygen may cost a few hundred dollars. Advanced care, including continuous monitoring, multiple medications, and hospitalization, can cost several thousand dollars. Prices vary by region and clinic. Ask the veterinarian for an estimate before they proceed with expensive treatments. Most clinics will discuss costs with you before beginning.

When to Stop CPR

You should stop CPR in three situations. First, if the dog starts breathing on its own and shows signs of life, such as moving, blinking, or lifting its head. Second, if you are physically exhausted and cannot continue effective compressions. Third, if a veterinarian tells you to stop. Do not stop simply because you are tired after a minute, fatigue is expected. Push through it as long as you can. If the dog has been unresponsive for more than 20 minutes of continuous CPR, the chances of recovery are very low, but the final decision to stop should be made by a veterinarian whenever possible.

CPR is a bridge, not a cure. It buys time until advanced care is available. Even with perfect CPR, many dogs do not survive cardiac arrest. That is not your failure. Your job is to give your dog the best possible chance, and you are doing exactly that by trying.

Common Mistakes Owners Make During Dog CPR

When panic sets in, even well-meaning rescuers make errors. Knowing these pitfalls before an emergency helps you stay focused.

Compressing too slowly or too fast. Effective compressions need a steady rhythm of 100 to 120 per minute. That feels faster than most people expect. Count aloud or hum a fast song to keep pace. Too slow means blood stops reaching the brain. Too fast means the heart does not refill between squeezes.

Stopping compressions to check for a pulse. Every time you pause, blood flow stops completely. Do not stop to feel for a heartbeat. Keep compressing until a veterinarian tells you to stop, or until the dog shows clear signs of life such as breathing on its own or moving.

Pressing on the wrong spot. For most dogs, the compression point is the widest part of the chest, just behind the elbows. Pressing too far forward hits the shoulder. Pressing too far back risks damaging the liver or spleen. Place the heel of one hand on that widest point, put your other hand on top, and keep your elbows locked.

Giving breaths before starting compressions. In cardiac arrest, the priority is chest compressions. Start compressions immediately. Rescue breaths come after the first cycle of compressions. Delaying compressions to give breaths wastes precious seconds.

Using human CPR technique. Dogs lie on their side, not their back. You compress the chest wall, not the sternum like in people. And you breathe into the nose, not the mouth, while holding the dog's mouth closed.

Giving up too early. CPR is exhausting and emotionally draining. But dogs have survived with prolonged CPR when the underlying cause was reversible. If you are physically able, keep going until a veterinary team takes over or you are certain the dog has died.

How to Reduce the Chance of This Happening Again

CPR treats cardiac arrest, but it does not fix the cause. The most valuable step after an emergency is understanding what led to it. Many causes of collapse, such as heart disease, bloat, or toxin exposure, have warning signs you can learn to recognize.

Schedule regular veterinary checkups. A veterinarian can detect heart murmurs, arrhythmias, or other conditions before they cause collapse. The American Veterinary Medical Association provides guidance on preventive care and emergency preparedness for pet owners. Dogs with known heart conditions may need medication, dietary changes, or activity restrictions. Dosing must come from the treating veterinarian, never from memory or another pet's prescription.

Dog-proof your home. Many cardiac emergencies come from poisoning. Keep chocolate, grapes, xylitol gum, rat poison, and human medications out of reach. Know your dog's normal resting breathing rate. Count breaths per minute while the dog sleeps. A rate above 30 breaths per minute at rest can signal heart failure and warrants a veterinary visit.

Learn your dog's baseline. Know what normal gums look like, how fast the heart beats at rest, and how the dog reacts to exercise. Sudden changes in any of these are reason to call a veterinarian. The American Animal Hospital Association offers resources on life stage care and recognizing early signs of illness.

What Recovery and Ongoing Management Usually Look Like

If your dog survives cardiac arrest, the next hours and days are critical. The dog will be hospitalized, likely in an intensive care unit. Veterinarians will monitor heart rhythm, blood pressure, oxygen levels, and brain function. The dog may need oxygen therapy, intravenous fluids, or medications to support the heart. Some dogs wake quickly. Others remain unconscious for hours or days.

The biggest concern after resuscitation is brain damage. Every minute without oxygen increases risk. Dogs that receive prompt, high-quality CPR have the best chance of returning to normal function. Some dogs recover fully within days. Others have lasting neurological deficits, such as weakness, confusion, or vision problems.

The underlying cause determines long-term outlook. A dog with a reversible problem, such as a temporary toxin exposure or an anesthetic complication, may return to a normal life. A dog with severe heart disease faces ongoing management. That often means daily medication, a low-sodium diet, and restricted exercise. Your veterinarian will explain the specific plan and what to watch for at home.

Recovery time varies widely. Some dogs come home within a week. Others need months of rehabilitation. Be patient and follow every follow-up appointment. Ask your veterinarian what signs require an immediate return to the hospital, such as labored breathing, pale gums, or collapse.

Frequently Asked Questions

Can I hurt my dog by doing CPR wrong? Yes, it is possible to break ribs or bruise the lungs, especially in small or elderly dogs. But in cardiac arrest, the dog is already dying. The risk of injury from CPR is far less dangerous than doing nothing. Compressions that are too gentle do not help. Push firmly and steadily. If you feel a rib crack, adjust your pressure slightly but do not stop. Survival matters more than avoiding injury.

How do I know if my dog is actually in cardiac arrest? A dog in cardiac arrest is unconscious, not breathing, and has no heartbeat. Check for a pulse by pressing two fingers against the inside of the thigh where the leg meets the body. If you cannot find a pulse within 10 seconds, start CPR. Do not spend longer than that searching. If the dog is unconscious and not breathing, begin compressions even if you are unsure about the pulse.

Should I give rescue breaths if I am worried about disease? Your safety matters. If you are uncomfortable with mouth-to-nose breathing, perform hands-only CPR with continuous chest compressions. Compressions alone provide some air movement and are far better than stopping entirely. If you have a barrier mask or pocket mask, use it. In most cases, the risk of disease transmission from a dog is low, but your safety comes first.

How long should I keep doing CPR? Continue until a veterinary team takes over, until the dog shows clear signs of life, or until you are physically unable to continue. Some dogs respond within minutes. Others take much longer. If you are alone and exhausted, you may need to stop. That is a reasonable decision. You cannot help your dog if you collapse yourself.

What should I do after the dog starts breathing again? Do not celebrate and stop. The dog is still in critical danger. Keep the dog on its side, keep it warm, and transport it to the nearest emergency veterinary hospital immediately. Even if the dog seems alert, its heart rhythm may be unstable. Cardiac arrest can recur. Do not offer food or water. Do not delay transport.

Can I use a video call to get help during CPR? No. Remote care cannot guide hands-on CPR in real time, and it cannot replace emergency transport. The American Veterinary Medical Association explains that telemedicine works best for follow-up and non-emergency advice, not for active emergencies. Call your veterinarian while driving if you need reassurance, but do not wait for instructions. Start CPR immediately and get to a hospital.
