Pet Breath Counter
Calculate and track your dog or cat's resting respiratory rate. Compare to normal ranges and get guidance on when elevated breathing needs vet attention.

The resting heart rate (RHR) is one of the simplest and most valuable vital signs you can measure at home. Deviations from normal resting heart rate can be the first detectable sign of cardiac disease, pain, fever, anemia, hyperthyroidism in cats, or other significant health conditions. The Pet Heart Rate Calculator tells you the normal range for your pet's species, size, and age, and guides you through accurately measuring their heart rate at home.
Normal Resting Heart Rate Ranges
Use the table below to compare Normal Resting Heart Rate Ranges.
| Species / Category | Normal RHR (beats per minute) | Below Normal (bradycardia) | Above Normal (tachycardia) |
|---|---|---|---|
| Adult dog (medium-large breed) | 60-100 bpm | Below 60 bpm | Above 100 bpm at rest |
| Adult dog (small breed, under 20 lbs) | 80-120 bpm | Below 70 bpm | Above 120 bpm at rest |
| Puppy (under 1 year) | 100-160 bpm | Below 80 bpm | Above 160 bpm at rest |
| Adult cat | 160-200 bpm | Below 140 bpm | Above 220 bpm at rest |
| Kitten (under 1 year) | 200-260 bpm | Below 160 bpm | Above 260 bpm |
| Rabbit | 130-325 bpm | Below 120 bpm | Above 330 bpm |
| Guinea pig | 200-300 bpm | Below 180 bpm | Above 320 bpm |
How to Measure Your Pet's Heart Rate at Home
Method 1: Femoral Pulse (Dogs and Cats)
Place two fingers (not your thumb) on the inner thigh of your pet's rear leg, in the groin area where the leg meets the body. You should feel the femoral artery pulsing against your fingers. Count the beats for 15 seconds and multiply by 4 for beats per minute.
Method 2: Chest Auscultation (Hand on Chest)
Place your hand on the left side of the chest, just behind the elbow, and feel for the heartbeat. This method is easier in dogs than cats. Count beats for 15 seconds and multiply by 4.
Method 3: Digital Stethoscope / Smartphone Apps
Several apps (PetPace, Cardalis, Vet's Companion) use the phone microphone or dedicated sensors to record and count heart rate. These provide a more accurate reading than manual counting, especially for cats with very fast rates.
Conditions Associated with Abnormal Heart Rate
Use the table below to compare Conditions Associated with Abnormal Heart Rate.
| Condition | HR Effect | Additional Signs | Action |
|---|---|---|---|
| Congestive heart failure (CHF) | Tachycardia (fast) or bradycardia (slow, with heart block) | Cough (dogs), open-mouth breathing, exercise intolerance | Emergency if acute; urgent vet if new abnormality |
| Atrial fibrillation | Irregularly irregular rapid rate | Variable energy level; may be asymptomatic initially | Veterinary evaluation; ECG required |
| Sick sinus syndrome | Bradycardia; possible episodes of tachycardia (brady-tachy syndrome) | Episodic weakness or syncope (fainting) | Veterinary evaluation; may require pacemaker |
| Hyperthyroidism (cats) | Tachycardia | Weight loss despite appetite, hyperactivity, hypertension | Veterinary testing (T4); medical management |
| Pain or fever | Tachycardia | Context-dependent behavioral signs | Veterinary evaluation for underlying cause |
| Athletic bradycardia | Low-normal HR | Normal in very fit, large breed athletic dogs | No concern if dog is healthy and fit |
Frequently Asked Questions
My dog's heart rate was irregular when I counted. Should I worry?
Occasional irregular beats in dogs can be a normal phenomenon called respiratory sinus arrhythmia (RSA) - the heart rate increases during inhalation and slows during exhalation. This is a normal finding in relaxed healthy dogs. True arrhythmias (irregular rhythm that does not correlate with breathing) warrant veterinary investigation.
How is heart rate different from respiratory rate?
Heart rate measures heartbeats per minute (the cardiac cycle). Respiratory rate measures breaths per minute (the breathing cycle). Both are important vital signs that can be measured at home. Heart rate measures cardiovascular function; respiratory rate measures respiratory and cardiac function. Both should be monitored at rest in pets with known heart or lung disease.
Note: Heart rate changes with stress, activity, age, size, temperature, and health, so compare results with your pet's normal resting pattern.
