âNormalâ ranges from 60 to 140 beats per minute in a resting dog â 60 to 100 in big dogs and 100 to 140 in little ones. While you can check the rate with your hand over the heart, you can also take a pulse by gently feeling the beat near the inside top of your dog's hind leg. The heart rate will be the same both places, so do whichever is easier for you and your dog.
The heart rate is an important guide as to whether the heart is struggling or not. A cat's normal heart rate is approximately 120-140 beats per minute. A stressed cat will have a faster heart rate, meaning that the vet's measurement could be high. While a cat is at the vet, most vets consider up to around 180 beats per minute to be normal. Out of the vet's office, 180 beats is very concerning. A cat's heart may be beating fast to maintain circulation if its heart is failing.
