How to Do CPR on Your Dog: A Step-by-Step Emergency Guide

Few moments in a pet owner’s life are as terrifying as watching your dog become unresponsive. Knowing how to perform CPR on your dog could mean the difference between life and death in those critical minutes before you can reach emergency veterinary care. This guide walks you through exactly what to do — clearly, calmly, and step by step.

Common Causes

Understanding why a dog might need CPR can help you recognize a crisis faster and respond with confidence. Canine CPR is needed when a dog experiences cardiac arrest or stops breathing, and several emergencies can trigger this life-threatening situation.

• Drowning or choking: Airway obstruction or water inhalation can cause your dog to stop breathing suddenly, cutting off oxygen to the heart and brain.
• Traumatic injury: Being struck by a vehicle, a serious fall, or a physical impact can cause internal injuries that lead to cardiovascular collapse.
• Electrocution: Chewing on electrical cords is surprisingly common, particularly in puppies, and can cause immediate cardiac arrest.
• Severe allergic reaction (anaphylaxis): An extreme allergic response to an insect sting, food, or medication can rapidly compromise breathing and circulation.
• Underlying heart or respiratory disease: Dogs with pre-existing cardiac or pulmonary conditions are at higher risk of sudden collapse and may require emergency intervention with little warning.

Knowing these triggers won’t prevent every emergency, but awareness keeps you one step ahead when seconds matter most.

Symptoms to Watch For

Before beginning CPR, you must confirm that your dog actually needs it. Performing chest compressions on a conscious dog can cause serious harm, so take a brief moment — just a few seconds — to assess the situation carefully.

Look for the following signs that your dog may be in cardiac or respiratory arrest:

• Unresponsiveness: Your dog does not react to your voice, touch, or gentle stimulation.
• No visible breathing: The chest is not rising and falling, and you cannot feel air movement from the nose or mouth.
• No heartbeat or pulse: You cannot detect a pulse at the femoral artery (inner thigh) or feel a heartbeat behind the left elbow.
• Blue or pale gums: Grayish, white, or bluish gum color indicates a lack of oxygen in the bloodstream.
• Dilated pupils: Pupils that are fully dilated and unresponsive to light can signal a lack of brain oxygenation.
• Limp, unresponsive body: Complete muscle limpness with no reflexive movement is a strong indicator that intervention is needed.

If your dog is showing these signs, begin CPR immediately and have someone call an emergency veterinarian while you work.

What You Can Do at Home

Performing CPR on your dog follows many of the same principles as human CPR, though the technique is adapted for canine anatomy. Here is how to do it correctly.

Step 1: Check for Safety and Responsiveness
Make sure the environment is safe for both you and your dog. Call your dog’s name, tap their shoulder gently, and check for any response. If there is none, proceed immediately.

Step 2: Position Your Dog
Lay your dog on their right side on a firm, flat surface. This positioning allows easier access to the heart, which sits on the left side of the chest.

Step 3: Open the Airway
Gently tilt your dog’s head back to straighten the airway. Open their mouth, look inside for any visible obstructions, and carefully remove anything you can see. Do not perform a blind finger sweep.

Step 4: Give Rescue Breaths
Close your dog’s mouth gently with your hand. Place your mouth over their nose and blow steadily until you see the chest rise. Give two rescue breaths before beginning compressions. For small dogs and puppies, you can cover both the nose and mouth with your mouth.

Step 5: Begin Chest Compressions

• For large dogs (over 30 lbs): Place the heel of one hand over the widest part of the chest and place your other hand on top. Compress the chest by one-third to one-half of its width. Perform 30 compressions at a rate of 100–120 per minute.
• For small dogs and puppies (under 30 lbs): Use one hand to encircle the chest, placing your thumb on the left side and fingers underneath. Compress with your thumb at the same rate.
• For barrel-chested breeds like Bulldogs or Pugs: Position your dog on their back and compress the sternum directly, as you would a human.

Step 6: Continue the CPR Cycle
Alternate 30 chest compressions with 2 rescue breaths. Continue this cycle without stopping until your dog begins breathing on their own, a veterinarian takes over, or you have been performing CPR for 20 minutes with no response.

Do not stop to recheck for a pulse during compressions unless you observe clear signs of recovery, such as spontaneous breathing or movement.

When to See a Vet

CPR is a bridge — it is designed to keep your dog alive long enough to receive professional medical care, not to replace it. The moment you recognize your dog is in distress, contact an emergency veterinary clinic. If someone is with you, have them call ahead while you perform CPR so the team is ready upon your arrival.

Even if your dog recovers and begins breathing again on their own, an immediate veterinary evaluation is absolutely essential. The underlying cause of the collapse must be identified and treated, and your dog will need monitoring for complications such as brain injury, internal bleeding, or secondary cardiac events. Do not wait to see how your dog feels the next day — go directly to an emergency vet.

How Pet Insurance Can Help

A cardiac emergency can result in thousands of dollars in veterinary costs within hours, from emergency stabilization and diagnostic imaging to intensive care hospitalization. Having a pet insurance policy in place before a crisis occurs means you can focus entirely on your dog’s recovery rather than the financial burden. Many plans cover emergency care, hospitalization, and specialist visits, making them an invaluable safety net for moments exactly like this one.
