The ABCs of CPR refer to airway, breathing and circulation.
The first step when coming upon a pet who appears to be in trouble is to shake it to make sure it isn’t in a deep sleep. Then look in the mouth and remove any foreign objects that could be blocking the airway.
If the animal doesn’t appear to be breathing, place it on its right side and move to the front of the pet.
For a cat or small dog, cup your hands over its lips and breathe over its nose. For large dogs, cup your hands completely around the muzzle so air doesn’t escape and then breathe over the nose.
While the animal is still on its right side, lift the knee back to the chest where it meets the third to fifth rib space. Reposition the leg and place your hand over that area. Place the other hand under the chest. For smaller pets you can cup one hand and squeeze. For all animals the chest should be compressed about 30 percent.
Large dogs require 80 to 100 compressions per minute and small pets need more, about 100 to 120 compressions per minute. You should give two breaths for every 12 chest compressions.
Something may be lodged in your pet’s throat if you breath into the nose and the chest doesn’t expand. At this point, the Heimlich maneuver can be applied. The animal’s head should be down with its back against your chest while you give five swift squeezes over the abdomen to force the object out.
