Your Dog's Heart Rate:
How to Calculate a Dog's Heart Rate
Understanding your dog's resting heart rate is a vital part of monitoring their cardiovascular health. A heart rate that is consistently too high (tachycardia) or too low (bradycardia) can indicate underlying medical issues like heart disease, pain, or infection.
Where to Find the Pulse
The easiest way to find a dog's heart rate is to feel the heartbeat directly on the chest or at the femoral artery located in the groin area.
The Chest: Place your hand on the left side of the dog's chest, just behind the front leg (the elbow). This is where the heart is closest to the rib cage.
The Femoral Artery: Gently place your fingers on the inside of the hind leg, high up in the groin area where the leg meets the body.
The Mathematical Formula
To get the most accurate reading, you should count the beats for a set period and then convert that number into Beats Per Minute (BPM). If you count for 15 seconds, multiply the count by 4. If you count for 30 seconds, multiply by 2.
Always measure your dog's heart rate while they are resting or sleeping. Physical activity, stress, or excitement will naturally increase the heart rate. If you notice a heart rate that stays outside the normal range while your dog is calm, consult your veterinarian immediately.
