CPR for dogs: Essential steps and when to seek help

Cardiopulmonary resuscitation (CPR) is a critical emergency procedure for dogs experiencing cardiac arrest or respiratory failure. Knowing how to perform CPR can be lifesaving, but it’s essential to understand the correct techniques and seek immediate veterinary assistance.

Recognising the need for CPR in dogs

CPR is needed if your dog:

  • Stops breathing
  • Has no heartbeat or pulse
  • Is gasping or appearing to choke
  • It may also be indicated in puppies during whelping if the mother fails to resuscitate the offspring

 

Immediate steps before performing CPR

  1. Ensure safety: Before initiating CPR, assess the environment for any hazards to yourself or the dog, such as electrical wires or unstable surfaces. Never attempt CPR while driving.
  2. Position the dog: Lay your dog on its right side on a flat surface to facilitate effective compressions.

Performing CPR: The ABCs approach

A = Airway

  • Check to see if the nose and mouth are free of fluids/objects
  • Extend the tongue so you can see the back of the throat and clear the airway using your finger.

Note: Do not place your fingers in the mouth of a conscious animal – there is a risk of being bitten.

B = Breathing

  • If the animal is breathing, move to step 3.
  • If the animal is not breathing, provide oxygen via a mask attached to an oxygen cylinder or breathing bag.
  • “mouth to snout” can be performed but is discouraged due to the risk of zoonotic disease. This is done by sealing the mouth and lips by placing your hands around them, holding the muzzle closed and forcefully exhaling into the nose. 4-5 breaths are delivered rapidly before checking the animal. This can be repeated.
  • Dogs <15kg should be given 20-30 breaths/minute.
  • Large dogs >15kg should be given 20 breaths/minute.

Note: Do not do this to a conscious animal – there is a risk of being bitten.

C = Circulation

  • The heartbeat is often felt on the chest wall just behind the elbow, or it may be heard using a stethoscope.
  • The most reliable site to feel the pulse is the femoral pulse, which is up in the groin.
  • Kneel beside the animal, placing the palm of one hand over the heart and the other underneath the animal.
  • Compress the chest around 1-2cm in smaller animals, and 3-4cm in larger animals.
  • Perform five chest compressions for each breath, then check the animal.

Be persistent – it may take several minutes before an animal responds to CPR. If resuscitation efforts continue for beyond twenty minutes it is unlikely that an animal will be revived.

Note: Even when performed by an experienced veterinarian, CPR is not always successful. Some animals may be temporarily revived but ultimately die, and others may not respond, due to their underlying condition.

Always seek immediate veterinary assistance

While performing CPR can be crucial, it’s imperative to get your dog to a veterinarian as quickly as possible. Professional medical intervention provides the best chance for recovery.

Our North Melbourne Accident and Emergency department is open 365 days a year, no bookings required. If possible, we recommend calling to let us know you are on the way.

Other information

It is essential that you get your pet to the vet as soon as possible as the clinic will have enough staff, equipment and drugs to help stabilise and support your pet better. At the clinic, your vet may intubate your pet and deliver oxygen. Drugs such as adrenaline may be given to kick-start the heart.

If CPR is successful, most animals require intensive care and very close monitoring thereafter as they may arrest again or may require some time to return to normal. The underlying cause may require investigation and treatment.
