A quick-reference guide to normal heart rate, respiratory rate, and temperature ranges for common household pets.
Why Vital Signs Matter for Pet Owners
You don't need a medical degree to monitor your pet's basic health — but you do need a baseline. Vital signs like heart rate, respiratory rate, and body temperature are objective, measurable indicators of how well your pet's body is functioning. When you know what's normal for your animal, you're far better positioned to recognize when something has shifted.
This isn't about replacing veterinary care. It's about becoming a more informed advocate for your pet. A quick check before a vet call can help you describe symptoms clearly and accurately — something that genuinely improves the quality of care your pet receives. See our pet health checklist for a structured way to track and communicate these observations.
| Normal dog body temperature | 99.5–102.5°F (American Kennel Club Health Foundation) |
| Normal cat heart rate | 140–220 bpm (Merck Veterinary Manual) |
| Normal dog respiratory rate | 10–30 breaths/min (Merck Veterinary Manual) |
| Normal rabbit heart rate | 130–325 bpm (Exotic Animal Formulary) |
| Fever threshold (dogs & cats) | Above 103°F warrants vet contact (American Veterinary Medical Association guidance) |
| Best time to measure resting respiratory rate | While pet is sleeping |
Normal Ranges by Species
Vital sign ranges differ meaningfully between species — and even between sizes within a species. A small dog's resting heart rate is naturally faster than a large breed's. The table below reflects widely referenced clinical ranges; your veterinarian can tell you what's typical for your specific animal.
| Species | Heart Rate (bpm) | Respiratory Rate (breaths/min) | Body Temperature (°F) |
|---|---|---|---|
| Dog | 60–140 | 10–30 | 99.5–102.5 |
| Cat | 140–220 | 20–30 | 100.5–102.5 |
| Rabbit | 130–325 | 30–60 | 101–103 |
| Guinea Pig | 230–380 | 40–150 | 99–103.1 |
| Hamster | 250–500 | 35–135 | 98.6–101 |

Resting heart rate
The number of heartbeats per minute when an animal is calm and not engaged in physical activity. It is the most clinically meaningful baseline measurement for owners to track.
Respiratory rate
The number of complete breaths (one inhale and one exhale) an animal takes per minute. Elevated resting respiratory rates can indicate respiratory distress, pain, or fever.
Rectal temperature
A measurement of core body temperature taken with a thermometer inserted briefly into the rectum. It is the most accurate at-home method for dogs and cats.
Capillary refill time (CRT)
A quick check of circulation: press on your pet's gums, release, and count how long it takes for the pink color to return. Normal CRT is under two seconds; longer times can signal circulatory problems.
Tachycardia
An abnormally fast heart rate for the species and size. While exercise and stress can cause temporary tachycardia, a persistent elevated rate at rest should be evaluated by a veterinarian.
Bradycardia
An abnormally slow heart rate. In pets, bradycardia can be associated with certain toxins, hypothermia, or underlying cardiac conditions and should be assessed promptly.
How to Check Vital Signs at Home
Measuring your pet's vitals is straightforward with a little practice. Always take measurements when your pet is calm and resting — activity, stress, and heat all affect readings.
Heart Rate
Place your hand or a stethoscope on your pet's left side, just behind the front leg. Count beats for 15 seconds and multiply by four. Alternatively, feel for the femoral pulse on the inner thigh of a dog or cat.
Respiratory Rate
Watch the rise and fall of your pet's chest or flank. Count each full breath (in and out) for 30 seconds and double it. Do this while your pet is sleeping for the most accurate resting rate.
Body Temperature
A digital rectal thermometer gives the most reliable reading. Lubricate the tip slightly, insert gently about one inch for dogs and cats, and hold in place for the duration indicated by your thermometer model. Ear thermometers designed for pets can be used but are generally considered less precise.
Practice When Your Pet Is Healthy
The best time to learn how to take your pet's vital signs is before there's an emergency. Practice during calm moments so both you and your pet become comfortable with the process. Recording a few baseline readings in a health journal means you'll have a genuine personal reference — not just a species average — when something seems off.
Pairing vital sign awareness with body language cues gives you a much fuller picture of your pet's overall state.
Red Flags: When to Contact a Veterinarian
A single out-of-range reading isn't always cause for alarm — context matters. A dog panting after a walk will have an elevated respiratory rate; that's expected. But certain patterns warrant prompt veterinary attention.
Under 2 sec
Normal capillary refill time in dogs and cats
Capillary refill time is a quick gum-press test; anything slower may indicate poor circulation and warrants veterinary evaluation.
104°F+
Temperature threshold for urgent vet contact
Veterinary guidelines generally recommend contacting a vet promptly when a dog or cat's temperature exceeds 104°F, as heatstroke and infection can escalate quickly.
30 breaths/min
Resting respiratory rate that warrants monitoring in cats
Some veterinary cardiologists recommend tracking sleeping respiratory rate in cats; consistent readings above 30 breaths/min at rest may signal underlying heart or lung issues.
- Heart rate significantly above or below the species range at rest
- Labored, noisy, or open-mouth breathing in cats (almost always an emergency)
- Temperature above 104°F or below 99°F in dogs or cats
- Gums that are pale, blue, white, or tacky — a rapid indicator of circulation problems
- Persistent lethargy combined with any abnormal vital sign
If your pet has a known chronic condition, abnormal vitals carry additional significance. Our overview of chronic conditions like diabetes and kidney disease explains how these illnesses can affect baseline health.
