What is the average heart rate range for dogs?

The average heart rate range for dogs typically falls between 100 to 140 beats per minute. This range can vary depending on the dog's size, age, breed, and activity level, but for most domestic dogs at rest, a heart rate within this range is considered normal.

Larger dog breeds tend to have slower heart rates, often closer to the lower end of this spectrum, while smaller breeds may have faster heart rates that can approach the upper limit of this range. It's crucial for veterinary technicians to be familiar with these normal values, as they play a significant role in assessing a dog's health during examinations. Recognizing variations from this norm can help in identifying potential medical issues, making this knowledge vital for effective veterinary care.

The other options suggest heart rate ranges that are either too low or too high and do not accurately reflect the typical heart rate expected in average, healthy dogs. Understanding these averages allows veterinary professionals to provide better diagnostic and treatment information for canine patients.
