What is the normal resting respiratory rate range for dogs?

• A. 8-20 breaths/min
• B. 12-24 breaths/min
• C. 10-30 breaths/min
• D. 20-40 breaths/min

Answer: (C)

A healthy, resting dog breathes quietly about 10 to 30 times per minute. This range accommodates differences in size and age, with smaller dogs and puppies tending toward the higher end and larger dogs toward the lower end, all while at rest and not panting. When the rate is consistently higher than 30, it can indicate tachypnea from factors like pain, fever, respiratory or cardiac disease, heat stress, or hypoxia. If it dips below about 10, bradypnea may be due to sedation, anesthesia, brain injury, or serious illness. To measure accurately, calm the dog and count full breathing cycles for a full minute, recognizing that panting is not the same as resting respiration and can falsely elevate the count. The 10-30 breaths per minute range is the standard resting rate for a healthy dog.
