Respiration -10 to 30. The normal respiratory rate for dogs is 16 to 20 breaths per minute. The normal heartrate is 70 to 160 bpm. Large dogs tend to have slower heart rates so your dog should be in the 70 to 120 bpm range. This varies according to the cardiovascular fitness of the dog, too.

In this video, you will learn how to count your pet's resting respiratory rate (RRR). A normal dog's respiratory rate when resting or sleeping is quite low, less than 35 breaths in a minute. The RRR may increase when heart failure develops or with other breathing problems. You can provide useful information for your veterinarian by keeping a RRR diary and bringing it to your next appointment.
