Hi I had a question. What can cause a yorkie to have a low heart rate? I have a puppy that went to the vet and they got a 90 reading on her.. Had to go wait in the waiting area.. and some big dogs came in and got a 108 reading on her... but it was a hard to get that reading...went back a week later and they only got a 76. They herd no mummer, and she is breathing good. She eats ok, and she does not play a lot. She is about 15 weeks old. She sleeps a lot. She will play if we have her out, and try to get her to play...other than that .. she would rather just lay on our laps.
What is a normal yorkie heart rate... what might cause it to be so low?
Thanks for any help!
