Cardiopulmonary resuscitation, or CPR, is an emergency technique used when a pet’s heart has stopped beating or they have stopped breathing, situations that can arise from choking, drowning, severe trauma, electrocution, poisoning, or a sudden cardiac event. While pet CPR cannot replace immediate veterinary care, knowing the correct technique and recognizing when it is needed can meaningfully improve a pet’s chance of survival in the critical minutes before you can reach professional help.
When CPR Is Needed
CPR is only appropriate when a pet is unresponsive, not breathing, and has no detectable heartbeat or pulse, meaning it is already in cardiac or respiratory arrest, not simply weak, lethargic, or in pain. Before starting CPR, quickly check for responsiveness by calling the pet’s name and gently tapping or pinching a paw, look and listen for breathing by watching the chest for movement, and check for a heartbeat by placing a hand or ear against the left side of the chest just behind the front leg, or by feeling for a femoral pulse in the inner thigh. If there is no breathing and no heartbeat, CPR should begin immediately, ideally while someone else calls the nearest veterinary emergency clinic so you can transport the pet the moment initial resuscitation efforts begin.
Preparing to Perform CPR
Before starting compressions, quickly check the pet’s airway for any visible obstruction, such as a toy, bone fragment, or foreign object blocking the throat, and carefully remove it if you can do so without pushing it further in. Gently pull the tongue forward and extend the neck to straighten the airway. Position the pet on its right side on a firm, flat surface, since CPR is not effective on a soft bed or cushioned surface that absorbs compressions rather than transmitting them to the heart. If two people are available, one should perform compressions while the other gives rescue breaths and prepares for transport, since continuous CPR performed by one person alone is exhausting and less effective over time.
Performing Chest Compressions
Hand placement depends on the pet’s size and chest shape. For most dogs, place your hands over the widest part of the chest; for barrel-chested breeds, compressions are given directly over the heart, roughly at the point where the elbow touches the chest when the front leg is folded back; for small dogs and cats, encircle the chest with one hand, thumb on one side and fingers on the other, and compress directly over the heart. Compress the chest about one-third to one-half of its width, at a rate of 100 to 120 compressions per minute, allowing the chest to fully recoil between compressions. The general rhythm used in most pet CPR protocols is 30 compressions followed by 2 rescue breaths, repeated in cycles.
Giving Rescue Breaths
To give a rescue breath, close the pet’s mouth firmly, extend the neck slightly to align the airway, and breathe directly into the nostrils until you see the chest rise, which typically takes about one second per breath. For very small dogs and cats, you may need to cover both the nose and mouth with your own mouth to create an effective seal, given their small size. Watch for the chest to rise with each breath; if it does not, recheck for an airway obstruction before continuing. Continue cycles of 30 compressions and 2 breaths, reassessing for a return of breathing or heartbeat approximately every 2 minutes, and continue CPR until the pet begins breathing on its own, you reach veterinary care, or a veterinary professional advises you to stop.
Getting to Veterinary Care and Building Skills in Advance
CPR should always be performed while actively arranging transport to the nearest veterinary emergency facility, since even a pet who regains a heartbeat needs immediate professional evaluation and treatment to address the underlying cause of the arrest. If possible, have another person call ahead so the clinic can prepare for your arrival. Because performing CPR correctly under pressure is difficult without prior practice, many pet owners find it valuable to take a formal pet first-aid and CPR course, which typically includes hands-on practice on training mannequins and covers related emergency skills such as choking relief and wound care, building confidence and muscle memory before a real emergency ever occurs.
Frequently Asked Questions
How do I know if my pet needs CPR?
CPR is needed only when a pet is unresponsive, not breathing, and has no detectable heartbeat or pulse. Check responsiveness, breathing, and pulse quickly before starting, since CPR is not appropriate for a pet that is simply weak or in pain.
What is the compression rate for pet CPR?
The general guideline is 100 to 120 compressions per minute, compressing the chest about one-third to one-half of its width, in cycles of 30 compressions followed by 2 rescue breaths.
Can I do CPR on a cat the same way as a dog?
The general technique is similar, but for small dogs and cats you typically encircle the chest with one hand for compressions and may need to cover both the nose and mouth with your mouth when giving rescue breaths, due to their smaller size.
Should I still take my pet to the vet after successful CPR?
Yes, always. Even if a pet’s heartbeat and breathing return, immediate veterinary evaluation is essential to treat the underlying cause of the arrest and monitor for complications.
Where can I learn pet CPR properly?
Many veterinary clinics, animal hospitals, and organizations like the Red Cross or American Red Cross offer pet first-aid and CPR courses that include hands-on practice, which is the most reliable way to build confidence with the technique before an emergency.
