If the need arose, do you know how to perform pet CPR? Most people do not know. They assume that the method is the same as in humans but since the ribcage is formed differently than humans, CPR needs to be done differently. While I will not get into the specifics of CPR for your dog, cat or other small mammal, I will suggest you find out how. Your vet is a good source of information on how to do emergency CPR for your pet.
You might never have to use your knowledge of how to help revive your pet but it is good to know. Just think that one day you might be in care of an animal that has been diagnosed via ekg that it has heart trouble. You might have to use your CPR technique to help that animal.
