What is the normal range for a canine heart rate in beats per minute?

The normal range for a canine heart rate in beats per minute typically falls between 60 and 140 bpm, making this choice accurate. This range can vary based on factors such as age, breed, size, and overall health of the dog. For example, smaller breeds often have higher heart rates than larger breeds. Generally, resting heart rates for dogs can be lower during calm periods and may rise during exercise or excitement, which falls within this specified range.

While some options suggest much lower or higher heart rates, they do not adequately reflect the normal physiological range observed in healthy dogs. It's important for veterinary professionals and pet owners to be aware of these normal ranges, as deviations, especially significant increases or decreases in heart rate, could indicate underlying health issues that may require further investigation.
