How To Do Cpr On A Dog

Cardiopulmonary resuscitation (CPR) can mean the difference between life and death for a dog suffering from cardiac or respiratory arrest. While urgent veterinary care is always the priority, knowing how to perform correct CPR while en route to a vet or waiting for emergency services can give your dog the best chance of survival. This guide follows consensus recommendations from the American Veterinary Medical Association (AVMA) and the Australian Veterinary Association (AVA), and is designed for pet owners who may never need to use it but should be prepared.

Quick Q&A: Common Questions

Question: Can I hurt my dog while performing CPR on them? Answer: Yes, it is possible to cause injury such as broken ribs or lung damage, especially if you use excessive force. However, in a true cardiac arrest, the risk of injury is far outweighed by the threat of death. Following guidelines for appropriate compression depth and rate, and always reassessing for a pulse, minimises harm while maximising the chance of revival.

When to Perform CPR on a Dog

CPR should only be attempted when a dog is unresponsive, not breathing, and has no detectable heartbeat. First, ensure the scene is safe for both you and the pet. Then tap the dog and call their name loudly; if there is no reaction, check for breathing by watching the chest and listening for airflow. To check for a pulse, press two fingers gently into the femoral artery on the inner thigh. If you cannot find a pulse within 10 seconds, begin CPR immediately.

If you have a second person present, ask them to call a veterinarian and direct the call while you start compressions. Do not delay chest compressions to perform a lengthy pulse check in a motionless, apnoeic patient.

Step-by-Step Guide to Canine CPR

1. Position the Dog for Compressions

Lay the dog on their right side (left side up) on a firm, flat surface. The heart sits in the lower half of the chest, so if you are working with a deep-chested breed like a Dobermann or Irish Wolfhound, position yourself over the widest part of the chest. For small dogs and cats, place your thumb on one side of the sternum and your fingers on the other, compressing by squeezing. For medium to large dogs, place the heel of one hand directly over the heart (just behind the elbow where the chest is widest) and your other hand on top, locking your elbows.

2. Perform Chest Compressions

Compress the chest by one-third to one-half of its width, at a rate of 100 to 120 compressions per minute. Allow the chest to fully recoil after each compression to let the heart refill. If you are performing CPR alone, use a compression-to-ventilation ratio of 30:2 (30 compressions then 2 rescue breaths). If two rescuers are present, the ratio changes to 15:2. The CVMA (Canadian Veterinary Medical Association) and AVA both endorse these ratios for single-limbed rescuers and emphasise uninterrupted compressions as much as possible.

3. Open the Airway and Give Rescue Breaths

After completing a compression cycle, open the airway by gently tilting the dog's head back (only if no neck injury is suspected) and extending the chin forward. Close the dog's mouth and place your mouth completely over the nose, forming a seal. Breathe in until you see the chest rise. Give one breath every 5 to 6 seconds for a standalone rescue breathing scenario, but during CPR, deliver two breaths after every 30 compressions (or 15 if two rescuers). If the chest does not rise, reposition the head and try again, checking for obstructions in the mouth.

4. Continue and Reassess

Perform cycles of compressions and breaths for two minutes (approximately 5 cycles of 30:2), then stop briefly to recheck for pulse and breathing. If no signs of life reappear, continue CPR. If you are alone and the dog shows no response after 20 minutes of high-quality CPR, survival becomes extremely unlikely, and many veterinarians recommend stopping.

Common Mistakes and How to Avoid Them

• Compressing too fast or too slow: Use the beat of the disco song "Stayin' Alive" (120 bpm) to keep the correct rhythm.
• Pressing too softly or too hard: Aim for a depth of one-third to one-half the chest width; avoid "bouncing" on the chest.
• Interrupting compressions for too long: Keep pauses to less than 10 seconds when switching to breaths or checking for a pulse.
• Not allowing full chest recoil: Removing all pressure completely during the relaxation phase improves blood return to the heart.
• Delaying CPR to induce vomiting or give treatments: In a cardiac arrest, chest compressions come first. Do not try to make the dog vomit or administer oral medications.

Prevention and Preparation

The best way to avoid needing canine CPR is to prevent the conditions that cause arrest. Common triggers include heatstroke, electrocution, drowning, severe allergic reactions, and certain toxins (such as chocolate or oleander). Keep your dog at a healthy weight and avoid overexertion in hot weather. Consider attending a pet first aid course that includes hands-on CPR practice; many such programs are endorsed by the AVMA, AAHA (American Animal Hospital Association), and FVE (Federation of Veterinarians of Europe). Having a pet emergency kit with a muzzle, blanket, and a list of emergency veterinary contacts can also save precious minutes. Finally, learn where the femoral pulse is located and practice on a healthy dog so that you can find it quickly in a crisis.

While no pet owner ever expects to use CPR, being prepared with the correct technique and understanding when to apply it gives your dog the best possible chance in an emergency. Always follow up with veterinary care as soon as possible, even if the dog appears to recover, because underlying causes must be addressed.
