Why Smaller Animals Have Faster Heart Rates

Smaller animals generally have faster resting heart rates than larger animals, a pattern seen consistently across the animal kingdom, related to metabolic rate scaling with body size.

Context Matters When Reading a Heart Rate

Stress, excitement, and the exam environment itself commonly elevate a heart rate reading above the animal's true baseline resting rate - a single elevated reading during a vet visit isn't necessarily abnormal, which is why veterinarians consider the full clinical picture rather than a single measurement in isolation.
