Normal Dog Vital Signs: Temperature, Pulse and Breathing Rate

A healthy adult dog runs a temperature of about 101 to 102.5F (38.3 to 39.2C), a resting pulse somewhere between 60 and 140 beats per minute depending on size, and 15 to 30 breaths per minute at rest. Those ranges are useful, but your own dog's usual numbers are more useful still.

Vital signs help you describe a problem accurately to a vet. They do not diagnose anything, and a normal reading does not rule out a serious illness. If your dog looks wrong, go regardless of what the thermometer says.

The reference ranges

Puppies sit at the faster end of the heart-rate ranges and can run slightly warmer. A temperature above 104F or below 99F is an emergency, as is any blue or grey gum color.

How to take a temperature

Rectal is the accurate method, and a cheap digital thermometer does the job. Lubricate the tip, insert about an inch for a medium dog, and wait for the beep. It takes under a minute with a second person steadying the dog.

Ear thermometers made for pets are more comfortable but less consistent. Human forehead scanners are not usable on dogs at all — the readings are not comparable to a dog's core temperature.

A dog that just came in from a walk on a warm day will read high. Wait ten quiet minutes before measuring anything.

How to find a pulse

The easiest spot is the femoral artery, on the inside of the back leg where it meets the body. Press gently with two fingers, not a thumb, until you feel a pulse. Count beats for 15 seconds and multiply by four.

You can also feel the heartbeat directly through the chest wall, low behind the left elbow. On thin-chested dogs this is easier than the femoral pulse.

Excitement, heat and stress all raise the number, so a reading taken while your dog is delighted you are touching them is not a resting rate.

The sleeping breathing rate is the one worth learning

This is the single most valuable number an owner can track, and it is the easiest to get. Watch your sleeping dog's chest rise and fall and count one full breath — in and out — as one. Count for a full minute.

Most healthy dogs sit between 15 and 30. A dog that consistently sleeps above 30 should be seen, and that threshold is used routinely for dogs with diagnosed heart disease because a rising trend often shows up before the owner notices anything else.

Do not count while your dog is dreaming, twitching, or panting. Take the number two or three nights running before you act on it.

Gums tell you about circulation

Lift the lip and look. Normal is a moist bubblegum pink, though some dogs have pigmented gums, in which case check the inner eyelid or the tongue instead.

Press a pink area with a fingertip until it blanches white, then release. The color should return within two seconds. Slower than that suggests circulation is not doing its job — and combined with weakness, pale color or fast breathing, it belongs on the go-now list in dog emergency symptoms.

Build the baseline while nothing is wrong

Take these numbers on a boring Sunday when your dog is healthy and write them somewhere you will find later. Add the things that are not on the chart: how much water disappears from the bowl in a day, what their normal appetite looks like, how they usually rise from the floor.

The value shows up months later, when you can tell a vet "she normally sleeps at 18 breaths a minute and she has been at 34 for two nights" instead of "she seems a bit off." That difference genuinely changes how quickly a case gets triaged.

What to do with a bad number

One abnormal reading in a dog who is otherwise bright, eating and playing is usually worth repeating before you panic — technique errors are common. Two abnormal readings, or one abnormal reading in a dog who also looks unwell, is a call to your vet.

And an abnormal breathing effort — open-mouth breathing at rest, exaggerated belly movement, stretched-out neck — is an emergency no matter what the count says. That case is covered in dog breathing problems.
