What is the normal heart rate range for a medium-sized dog?

The normal heart rate range for a medium-sized dog typically falls between 70 to 120 beats per minute. This range reflects the physiological demands and characteristics of medium-sized breeds, which can vary in heart rate compared to smaller or larger dogs. Factors such as age, exercise level, health condition, and anxiety levels can also influence heart rate, but the general accepted range provides a baseline for assessing cardiac health in these dogs.

Understanding this range is crucial for veterinary assistants when monitoring patients, during routine check-ups, or when evaluating a dog in distress. Keeping track of heart rates helps in identifying abnormalities that could signify underlying health issues.

The other ranges provided do not accurately reflect the heart rate normalcy for medium-sized dogs, as they either indicate rates that are too low or too high for this category.
