Your dog is lying around, skipping dinner, and feels warm. Is it a fever? You can't tell by touching a nose, and a human forehead thermometer won't work through all that fur. A dog thermometer gives you a number to tell the vet. Here are the 5 best dog thermometers in 2026, ranked by Amazon ratings and review counts. They include rectal digital models and no-contact and ear models. We didn't personally test them, and none of this replaces a vet. We went through the listings and what buyers say. For ear-only options, see our dog ear thermometer guide.
What to Look For in a Dog Thermometer
Rectal, ear or no-contact. A rectal digital thermometer is the usual choice for accuracy, and it is what most vets use. Ear and no-contact models are easier on a nervous dog, but they can read differently, so use them as a quick check.
Flexible tip. A bendy tip is more comfortable. A rigid tip is fine for large dogs but less forgiving if your dog wiggles.
Speed. Some give a reading in about 10 to 20 seconds. That matters with a squirmy dog.
Memory and alarm. Some save the last reading and beep at a high temperature.
Cleaning. Pick a waterproof tip, or use probe covers. Wipe it with alcohol after each use and keep it just for the dog.

How to Take Your Dog's Temperature
- Have a helper hold your dog gently.
- Cover the tip with a probe cover or petroleum jelly.
- Lift the tail and slide the tip in about an inch.
- Wait for the beep, then read the number.
- Clean the tip with alcohol, and write down the reading and the time.
A normal dog temperature is roughly 100.5 to 102.5 degrees F. If it is above 103 or below 99, call your vet.
