How Do I Perform CPR on a Dog or Cat?

Cardiopulmonary resuscitation (CPR) is a lifesaving procedure that can be used when a pet’s heart or breathing has stopped. While the idea of performing CPR on a dog or cat can feel intimidating, knowing the basic steps can make the difference in an emergency until professional veterinary help is available. The process for animals is similar in principle to human CPR but requires adjustments based on their size and anatomy.

When to Use CPR on Pets

CPR should only be performed if your pet is unresponsive, not breathing, and you cannot feel a heartbeat. Signs that may indicate the need for CPR include:

  • No chest movement or breathing sounds

  • Gums or tongue appearing blue or gray

  • Lack of responsiveness when called or touched

  • No detectable pulse

These signs are indicative of cardiopulmonary arrest (CPA), a critical emergency that requires immediate action to improve the chances of a successful outcome.

Because CPR is physically demanding and not always successful, it should only be attempted in clear emergencies while someone else contacts a veterinarian.

Preparing for CPR

Being prepared to perform CPR on your dog or cat can make all the difference in a veterinary emergency. As a pet owner, understanding the basics of veterinary resuscitation—including how to perform chest compressions and give rescue breaths—can help you act quickly and confidently if your pet experiences cardiac arrest.

Familiarize yourself with your pet’s chest anatomy, as the technique for chest compressions varies between small dogs, cats, and larger or deep-chested dogs. For smaller dogs and cats a one-handed technique, gently encircling the chest with your fingers and thumb. For large breed dogs or deep-chested dogs, such as English Bulldogs, a two-handed or circumferential compression technique may be necessary to ensure effective compressions without causing injury. The RECOVER initiative, led by veterinary professionals and associate professors in critical care, provides detailed guidelines and a CPR algorithm to help pet owners and veterinary teams save lives.

When you begin CPR, start with chest compressions at a rate of 100 to 120 compressions per minute, followed by two rescue breaths after every 30 compressions. This 30:2 ratio is recommended for both dogs and cats, and is especially important during single rescuer CPR. Remember to push hard and fast, compressing about one-third of the animal’s chest width, to help restore spontaneous circulation.

Preparation also means having a plan in place for veterinary emergencies. The Critical Care Society advises pet owners to know the location and contact information of the nearest veterinary hospital, so you can transport your pet for advanced care as soon as possible. Quick action and access to professional veterinary medicine can significantly improve your pet’s chances of recovery.

While there are risks associated with performing CPR—such as potential injury to the animal or the person providing aid—proper training and adherence to established guidelines greatly increase CPR effectiveness. The RECOVER initiative encourages both veterinary professionals and pet owners to take a CPR course and stay updated on the latest techniques and recommendations in basic life support and critical care.

Unlike human medicine, where CPR is performed with the patient on their back, dogs and cats should be placed in lateral recumbency (on their side) for resuscitation. Make sure the animal’s nose and mouth are clear of debris, and use your fingers underneath the chest to provide support during compressions.

For certain breeds, such as wide-chested or round-chested dogs, modifications to the standard technique may be needed. For example, English Bulldogs may benefit from circumferential compressions, as recommended by the co-chair of the RECOVER initiative.

Ultimately, preparing for CPR means combining knowledge, skills, and readiness to act. By learning the proper techniques, having a veterinary hospital plan, and staying informed about new guidelines in veterinary medicine, pet owners can help save lives and improve outcomes for their beloved pets. Remember: push hard, push fast, and give rescue breaths to give your pet the best chance at survival in a critical care situation.

Step 1: Check Responsiveness and Airway

First, gently shake or call your pet to see if they respond. If they remain unresponsive, check the airway. Lay the pet on their side and open the mouth, clearing any visible obstructions such as vomit, toys, or food. Make sure the tongue is pulled forward so it does not block the airway.

Step 2: Provide Rescue Breaths

If the airway is clear but the pet is not breathing, give rescue breaths. Close the mouth and extend the neck to open the airway. For dogs, seal your lips around the nose. For cats and very small dogs, seal your lips around both the nose and mouth. Deliver a breath by blowing gently into the animal's snout until you see the chest rise, then release to let the air flow out. The amount of air delivered per breath should be appropriate for the animal's size, aiming for the recommended tidal volume per kilogram of body weight. Give two breaths before moving to compressions.

Step 3: Perform Chest Compressions

The technique for chest compressions depends on the size of the animal. If the animal is unresponsive and not breathing, start chest compressions immediately. After confirming there is no breathing or pulse, start CPR as soon as possible.

To perform compressions, place your hands over the widest part of the animal's chest. Make sure your shoulders are directly above your hands to apply effective force and maintain proper technique.

Medium to Large Dogs

  • Place the dog on its right side.

  • Position your hands over the widest part of the rib cage, not directly over the heart.

  • Push down about one-third of the chest’s width.

  • Aim for 100 to 120 compressions per minute.

Small Dogs and Cats

  • Place one hand around the chest so your fingers and thumb meet at the ribs just behind the front legs.

  • Compress gently using your thumb on one side and fingers on the other.

  • Push down about one-third of the chest’s width.

  • Maintain the same rhythm of 100 to 120 compressions per minute.

Step 4: Combine Breaths and Compressions

The standard ratio is 30 compressions followed by two rescue breaths, repeated continuously. If two people are available, one can provide compressions while the other handles breathing. Continue CPR until the pet starts breathing again, a pulse is detected, or veterinary professionals take over.

Step 5: Seek Veterinary Care Immediately

Even if your pet responds to CPR, they must be taken to a veterinarian right away. Underlying causes, such as heart disease, trauma, or choking, require urgent treatment. CPR is a temporary measure to restore breathing and circulation until professional help is available.

Important Considerations

  • Do not attempt CPR if the pet is still breathing or has a heartbeat, as it can cause harm.

  • Practice gentle but firm compressions—too light may be ineffective, but too strong may cause injury.

  • Learn pet first aid through training whenever possible, as real practice builds confidence and skill.

Conclusion

Performing CPR on a dog or cat can be lifesaving in an emergency. The steps include checking responsiveness and the airway, providing rescue breaths, delivering chest compressions appropriate for the pet’s size, and continuing until professional help is available. While success rates vary, being prepared and acting quickly gives your pet the best chance of survival.

FAQs

How do I know if my pet needs CPR?

Your pet may need CPR if they are unresponsive, not breathing, and you cannot feel a heartbeat.

Is CPR on pets the same as on humans?

The principles are similar, but techniques are adjusted for the size and anatomy of dogs and cats.

How fast should compressions be for a dog or cat?

Aim for about 100 to 120 compressions per minute, similar to the rhythm used in human CPR.

Can CPR hurt my pet?

CPR can cause injury, such as broken ribs, but in a life-threatening emergency, the benefits outweigh the risks.

Should I still take my pet to the vet after successful CPR?

Yes, veterinary care is essential after CPR, even if your pet appears to recover, to address underlying causes and prevent further complications.
