Why is my dogs heart beating so fast? Pet's info: Dog | Rottweiler | Male | unneutered

Linda G, MS, DVM · Accepted Answer

Hello. The normal heartbeat of a dog should be around 120-160 beats per minute. If his heartrate is greater than 200 beats per minute at rest or when sleeping, this is abnormal & could be due to a conduction disorder in the heart. He may also have an abnormal rhythm that mimics a elevated heart rate. The only way to sort out what might be happening is to have your veterinarian auscultate his heart & possibly do any ECG to identify the rate & any rhythm abnormalities. I hope all is OK & thanks for using Petco Pet Education Center, formerly Petcoach.
