# How to Safely Perform CPR on a Dog: A Step-by-Step Emergency Guide


## Key Takeaways

- CPR is indicated only for dogs that are unconscious, not breathing, and have no detectable heartbeat. Performing CPR on a dog with a heartbeat can cause serious injury.
- The primary goal of CPR is to maintain blood flow and oxygenation to vital organs, particularly the brain, until professional veterinary care can be initiated. Brain cells begin to die within 3-5 minutes without oxygen.
- CPR involves cycles of 30 chest compressions followed by 2 rescue breaths. Compressions should be delivered at a rate of 100-120 per minute, compressing the chest approximately one-third of its width.
- Rescue breaths are administered by closing the dog's mouth and breathing into its nose until the chest rises. For small dogs, the mouth may cover both the nose and mouth.
- CPR should be continued until the dog resumes spontaneous breathing and heartbeat, a veterinarian takes over, or the rescuer is physically unable to continue. Transport to an emergency veterinary facility should commence immediately, even if the dog revives.
- Common causes of cardiac arrest in dogs include severe trauma, choking, drowning, electric shock, and poisoning. Prompt identification and management of the underlying cause are critical for survival.

If your dog has collapsed, is not breathing, or has no heartbeat, start CPR immediately and keep going until you reach a veterinary emergency room. Do not stop to search online or call a friend. Every second without oxygen damages the brain and vital organs. If your dog is unconscious, not breathing, or you cannot feel a heartbeat, this is a life-threatening emergency. Move your dog carefully to a flat, firm surface and begin the steps below while someone else drives you to the nearest open emergency veterinarian.

CPR stands for cardiopulmonary resuscitation. It combines chest compressions to pump blood and rescue breathing to deliver oxygen. Dogs rarely need CPR from a heart attack like people do. More often, CPR is needed after choking, drowning, electric shock, severe trauma, or poisoning. The cause matters less than the response. Your job is to keep blood and oxygen moving until a veterinarian can take over.

Do not perform CPR on a dog that is breathing normally or has a strong heartbeat. Check first. A dog that is merely unconscious but still breathing needs immediate transport to a vet, not chest compressions. Pressing on a beating heart can cause serious injury.

The American Veterinary Medical Association (AVMA) emphasizes that first aid is not a substitute for veterinary care. Your goal with CPR is to buy time, not to fix the underlying problem. Even if your dog revives, you must still go to an emergency clinic immediately. [AVMA Emergency Care for Pets](https://www.avma.org/resources-tools/pet-owners/emergencycare)

## What Is Most Likely Going On?

When a dog collapses and stops breathing, the heart usually stops within a minute or two. This is called cardiac arrest. The heart is a muscular pump. When it stops, blood no longer carries oxygen to the brain, kidneys, and other organs. Without oxygen, brain cells begin to die within three to five minutes. CPR manually squeezes the heart and lungs to keep oxygenated blood flowing.

The most common causes of cardiac arrest in dogs include severe trauma such as being hit by a car, drowning, choking on a foreign object, electric shock from chewing a cord, and certain toxins. The ASPCA Animal Poison Control Center notes that many household substances, including chocolate, xylitol, and some human medications, can cause collapse or seizures. If you suspect poisoning, call the ASPCA Animal Poison Control Center at (888) 426-4435 while en route to the vet. [ASPCA Animal Poison Control Center](https://www.aspca.org/pet-care/animal-poison-control)

## What Else Could It Be?

Not every collapse means the heart has stopped. A dog can lose consciousness from a seizure, a sudden drop in blood pressure, heatstroke, or severe pain. Some dogs faint briefly and recover on their own. Others stop breathing but still have a heartbeat, a condition called respiratory arrest. In that case, rescue breathing alone may be enough until the dog breathes on its own.

The only way to know for certain is to check. Look at the chest for movement. Listen for breath sounds. Feel for a pulse. In dogs, the easiest pulse to find is the femoral artery, located on the inside of the back leg where the leg meets the body. Press gently with two fingers. If you cannot find a pulse within 10 seconds, start chest compressions.

## When To Start CPR

Start CPR only when all three are true: the dog is unconscious, not breathing, and has no detectable heartbeat. If you are unsure whether the heart is beating, start compressions anyway. The risk of doing CPR on a dog with a weak heartbeat is far lower than the risk of doing nothing while the brain loses oxygen.

Before starting, check the airway. Open the mouth gently and look for a foreign object such as a toy, bone, or stick. If you can see an object and remove it easily with your fingers, do so. Never push your fingers deep into the throat. If the airway is clear, tilt the head slightly to open the breathing passage. Do not tilt a dog's neck if you suspect a spinal injury from trauma. In that case, keep the head and neck in a straight line with the body.

## When To Stop CPR

Continue CPR until one of these happens: the dog starts breathing on its own, you feel a heartbeat, a veterinarian takes over, or you are physically unable to continue. Do not stop after one minute to see if the dog improves. Effective CPR is exhausting, and many owners cannot sustain it for long. If you have another person with you, switch roles every two minutes to keep compressions strong.

If the dog revives, stop compressions immediately but keep the dog warm and calm. Transport to an emergency clinic right away, even if the dog appears normal. The underlying cause has not been treated, and cardiac arrest can recur. The MSD Veterinary Manual advises that any pet that has experienced cardiac arrest needs immediate and ongoing veterinary care to address the cause and prevent further episodes.

## What You Can Do Right Now, Safely

Your first job is to protect yourself and the dog. A dog in pain or panic may bite, even a normally gentle pet. If the dog is conscious, approach slowly and speak in a low, calm voice. Do not put your face near its mouth. If the dog is unconscious, check that the area is safe before you touch it.

Do not give the dog anything by mouth. No water, no food, no medication. A dog that cannot swallow properly can inhale liquid into its lungs, which can cause pneumonia or choking. If you suspect poisoning, do not induce vomiting unless a veterinarian or the ASPCA Animal Poison Control Center tells you to do so. Some toxins cause more damage coming back up than going down.

Do not attempt CPR on a dog that is breathing or has a heartbeat. Chest compressions on a beating heart can cause serious injury. If you are unsure whether the dog is breathing, watch the chest and abdomen for movement for no more than 10 seconds. Place your hand just in front of the dog's nose and mouth to feel for air. If you see or feel any breath, do not start compressions.

If the dog is not breathing but has a heartbeat, you may need rescue breathing only. If there is no heartbeat, you will need full CPR. The next section walks you through both.

## Step-by-Step CPR for Dogs

CPR stands for cardiopulmonary resuscitation. It combines chest compressions with rescue breathing to keep blood and oxygen moving through the body when the heart and lungs have stopped working. The American Veterinary Medical Association notes that first aid is meant to stabilize a pet for transport, not replace veterinary care. CPR buys time until you reach a hospital.

Follow these steps in order.

**Step 1: Confirm unresponsiveness and check breathing.** Call the dog's name loudly. Gently tap its shoulder. If there is no response, check for breathing for up to 10 seconds. If the dog is not breathing, proceed immediately.

**Step 2: Position the dog.** Lay the dog on its right side on a firm, flat surface. A floor is better than a bed or sofa. Straighten the head and neck so the airway is open. Pull the tongue forward gently so it does not block the throat.

**Step 3: Check for a heartbeat.** Place two fingers on the dog's chest, just behind the elbow, where the left front leg meets the chest wall. Press gently. Feel for a pulse for up to 10 seconds. If you cannot find one, begin compressions.

**Step 4: Give chest compressions.** Place the heel of one hand on the widest part of the chest, just behind the elbows. For larger dogs, place your other hand on top and interlace your fingers. For small dogs under 15 kilograms, about 33 pounds, you can use one hand or even two fingers. Compress the chest about one third of its width. Push straight down and let the chest fully rebound between compressions. Aim for 100 to 120 compressions per minute. Count aloud to keep a steady rhythm.

**Step 5: Give rescue breaths.** After every 30 compressions, give two breaths. Close the dog's mouth and place your mouth over its nose. Blow gently until you see the chest rise. Do not blow hard. For small dogs, your mouth may cover both the nose and mouth. Give each breath over about one second.

**Step 6: Continue the cycle.** Repeat 30 compressions followed by two breaths. Stop every two minutes to check for breathing and a heartbeat. If the dog starts breathing on its own, stop CPR and keep the dog warm and quiet.

**Step 7: Transport immediately.** CPR is not a cure. It is a bridge. Carry the dog to the nearest emergency veterinary hospital while continuing CPR if needed. If you have another person with you, one can drive while the other performs compressions.

| Dog Size | Hand Position | Compression Depth | Compression Rate |
|----------|---------------|-------------------|------------------|
| Small under 15 kg | One hand or two fingers | About one third of chest width | 100 to 120 per minute |
| Medium 15 to 30 kg | Two hands, one over the other | About one third of chest width | 100 to 120 per minute |
| Large over 30 kg | Two hands, one over the other | About one third of chest width | 100 to 120 per minute |

## What Not to Do During CPR

Do not compress the abdomen. That does not move blood effectively and can damage internal organs. Do not press on the ribs themselves. You want the heel of your hand over the heart area, not over bone. Do not stop compressions for more than a few seconds. Every pause reduces blood flow to the brain.

Do not give rescue breaths to a dog that is breathing on its own. Do not blow air into the stomach. If you see the abdomen rise instead of the chest, reposition the head and neck and try again. Do not attempt CPR on a dog that has a heartbeat. Check carefully before you start.

Do not use human CPR techniques on a dog. The hand position, compression depth, and breath method are different. Human CPR uses two rescue breaths after 30 compressions, but the hand placement and force do not translate directly to canine anatomy.

## What to Write Down Before You Call the Vet

When you reach the veterinary hospital, the team will need information quickly. Write these details down or say them clearly when you call ahead.

- The dog's approximate weight in kilograms or pounds
- How long the dog was unconscious or not breathing before CPR started
- Whether the dog had a heartbeat when you started
- How many minutes of CPR you performed
- Whether the dog ever resumed breathing on its own
- Any known medical conditions, such as heart disease or epilepsy
- Any possible cause, such as trauma, choking, poisoning, or a seizure
- The dog's age and sex

If you suspect poisoning, note what the dog may have eaten, when, and how much. The ASPCA Animal Poison Control Center can advise on specific toxins, but in an emergency, call your veterinarian first and then the poison center if directed. Do not wait for a phone call to start CPR if the dog is not breathing.

## What Happens at the Veterinary Hospital

At the hospital, the veterinary team will take over CPR if the dog is still not breathing. They have equipment you do not have, including oxygen, intravenous fluids, and medications to support heart function. They may place a breathing tube to protect the airway and deliver oxygen directly to the lungs.

The veterinarian will ask you the same questions listed above. They will also examine the dog for injuries, check gum color, and listen to the heart and lungs. Common tests include blood work to check organ function, an electrocardiogram to assess heart rhythm, and X-rays to look for trauma or fluid in the chest.

The cost of emergency care varies widely by region and clinic. A basic emergency visit with CPR and stabilization can range from several hundred to over a thousand dollars. Advanced care, such as intensive monitoring or surgery, can cost more. Ask the hospital for an estimate before they proceed with non-emergency tests. Do not let cost concerns stop you from seeking care. Many hospitals offer payment plans or can direct you to financial assistance programs.

## Your CPR Decision Flowchart

Use this flowchart to guide your actions in the moment. Print it or save it on your phone before an emergency happens.

| Observation | Action |
|-------------|--------|
| Dog is conscious and breathing | Do not do CPR. Call your veterinarian for advice. |
| Dog is unconscious but breathing | Do not do CPR. Keep the dog warm and transport immediately. |
| Dog is not breathing but has a heartbeat | Start rescue breathing only. Give one breath every 5 seconds. Transport immediately. |
| Dog is not breathing and no heartbeat | Start full CPR. 30 compressions, then 2 breaths. Continue until help arrives or the dog revives. |
| Dog resumes breathing during CPR | Stop CPR. Keep the dog warm and quiet. Transport immediately. |
| You are exhausted and cannot continue | Stop CPR. Transport immediately. Do not delay transport to continue CPR. |

CPR is physically demanding. If you cannot maintain the correct compression rate, it is better to transport the dog quickly than to perform ineffective compressions. The goal is to get the dog to a veterinarian who can provide advanced life support. Your efforts matter, but they are only one part of the rescue.

## Common Mistakes Owners Make During Dog CPR

When panic sets in, even well-meaning rescuers make errors that reduce the dog's chance of survival. Knowing these mistakes before an emergency helps you act correctly under pressure.

**Mistake: Starting CPR when the dog still has a heartbeat.** Pumping the chest of a dog with a beating heart can cause serious injury. Always check for at least 10 seconds but no more than 15 seconds. Look for chest movement, feel for breath on your cheek, and press two fingers firmly against the inside of the upper thigh to find a pulse. If you feel a heartbeat or see breathing, do not start compressions. Instead, keep the dog warm, keep the airway open, and rush to the nearest emergency hospital.

**Mistake: Compressing too slowly or too gently.** Effective CPR requires force. For a medium or large dog, you must push hard enough to compress the chest by one-third to one-half of its width. Aim for 100 to 120 compressions per minute. If you are not physically tiring, you are likely not pushing hard enough. Switch with another person every two minutes if possible.

**Mistake: Stopping compressions to move the dog.** Once you start CPR, you should continue until the dog revives, you are physically exhausted, or a veterinary team takes over. Pausing to load the dog into a car can waste precious minutes. If you must move the dog, do it between compression cycles and keep the pauses under 10 seconds.

| Common Mistake | What To Do Instead |
| --- | --- |
| Compressing too gently | Push hard enough to compress the chest by one-third to one-half its width |
| Stopping to check for a pulse every few seconds | Check once every 2 minutes, between compression cycles |
| Giving breaths too forcefully | Blow gently until you see the chest rise, then stop |
| Tilting the head too far back | Keep the head and neck in a neutral, straight line |
| Doing CPR on a dog that is breathing | Confirm no breathing and no pulse before starting |

## How to Reduce the Chance of This Happening Again

You cannot always prevent the underlying cause of cardiac arrest, but you can lower the risks that lead to it.

Keep toxic substances out of reach. Chocolate, xylitol gum, grapes, raisins, onions, and certain medications can trigger dangerous heart rhythms or collapse. The ASPCA Animal Poison Control Center lists common household hazards and can guide you on urgent response if your dog ingests something harmful. Store these items in sealed cabinets your dog cannot open.

Maintain a healthy weight. Obesity strains the heart and increases the risk of heart disease. Ask your veterinarian about an appropriate diet and exercise plan for your dog's breed and age.

Schedule regular veterinary checkups. Many heart conditions are detected early during routine exams before they cause collapse. The American Animal Hospital Association provides guidance on preventive care and life stage health that can help you catch problems early.

Know your dog's normal resting breathing rate. Count breaths per minute while your dog sleeps. A rate above 30 breaths per minute at rest can signal heart trouble and warrants a veterinary visit.

## What Recovery and Ongoing Management Usually Look Like

If your dog survives cardiac arrest, the recovery path depends on the underlying cause. Dogs that revive quickly and reach a hospital within minutes have the best outlook. The veterinary team will stabilize your dog, provide oxygen, run blood tests, and monitor heart rhythm continuously.

Most dogs that survive CPR stay in the hospital for at least 24 to 72 hours. During this time, veterinarians watch for brain damage, fluid in the lungs, or repeat arrest. Some dogs need medications to support heart function. Others require surgery if a blockage or trauma caused the arrest.

After discharge, your dog may need restricted activity for several weeks. Follow the veterinarian's instructions on exercise limits, medication timing, and follow-up appointments. Some dogs recover fully and return to normal life. Others may have lasting heart or neurological issues that require long-term management. Your veterinarian will create a plan based on your dog's specific condition, as described in the American Veterinary Medical Association's emergency care guidance.

## Frequently Asked Questions

**How long should I keep doing CPR before giving up?**

Continue CPR until the dog starts breathing on its own, you are too exhausted to continue, or a veterinary professional tells you to stop. In the field, many owners stop too early because they are tired or discouraged. If you can, switch with another person every two minutes. If you are alone, keep going as long as you physically can. Even after 10 or 15 minutes, some dogs can still revive, especially if the arrest was caused by choking or drowning.

**Can I hurt my dog by doing CPR wrong?**

Yes, CPR can cause rib fractures, lung damage, or liver injury, especially in small dogs or puppies. This is why you must only start CPR when the dog is truly not breathing and has no pulse. However, a dog in cardiac arrest is already dying. The risk of injury from CPR is acceptable when the alternative is death. Use the correct hand position and compression depth for your dog's size.

**Should I give rescue breaths or just chest compressions?**

For a dog that collapsed from a heart problem, chest compressions matter most. For a dog that stopped breathing first, such as from choking or drowning, rescue breaths are critical. The safest approach is to do both: give two rescue breaths after every 30 compressions. If you are unwilling to give mouth-to-snout breaths, perform continuous chest compressions until help arrives.

**What if my dog starts breathing again during CPR?**

Stop compressions immediately. Place the dog on its side with the head slightly extended to keep the airway open. Watch for normal breathing and check for a pulse. Keep the dog warm and calm. Even if your dog seems fine, you must still go to an emergency veterinarian. The underlying cause of the arrest can happen again without warning.

**How do I know if my dog has a pulse?**

Place two fingers on the inside of the upper thigh, where the leg meets the body. Press gently until you feel a pulse. You can also feel for a pulse on the inside of the front leg, just above the elbow. If you cannot find a pulse within 10 to 15 seconds, start CPR. In an emergency, it is better to start CPR than to spend too long searching for a pulse.

**Will my dog be the same after surviving cardiac arrest?**

Some dogs recover completely with no lasting effects. Others may have memory problems, weakness, or difficulty walking if the brain lacked oxygen for too long. Heart function may also be permanently affected. Recovery takes time, often weeks to months. Work closely with your veterinarian on rehabilitation, medication, and follow-up testing. Every dog is different, and your veterinary team will guide you based on your dog's response.
