Buyer's Guide: How to Choose the Best Dog Thermometer

When deciding what sort of thermometer to buy for your canine companion, there are a few factors to consider. Because dogs’ temperatures cannot be taken orally, the best approach to take your pet’s temperature is using a rectal, ear, or infrared thermometer.

Getting the correct thermometer for your pet’s needs will go a long way toward making them comfortable with having their temperature monitored on a regular basis. Other factors to consider when selecting a thermometer are its price and ease of use.

We’ll go through the many sorts of thermometers, how they’re used, and how much they typically cost.

Types of Thermometers

Rectal Thermometer

These are the most popular and least expensive types of thermometers available for use with your pet. Before placing the tip straight into your pet’s rectum, lubricate it with vaseline or another lubricant.

Because our four-legged pals are obviously not lovers of this form of temperature measurement, speed and precision are critical considerations when selecting a rectal thermometer.

If you know your pet may try to wiggle away, consider a thermometer with a quick temperature readout time. A rectal thermometer with a flexible rubber tip will likely reduce your pet’s uneasiness because it will not feel as harsh and alien.

Many rectal thermometers have an LCD screen that allows you to quickly see the temperature. Taking your pet’s temperature via their rectum may appear intimidating, but this procedure typically yields the best reliable readings and is regarded the current standard in veterinary treatment.

Thermometer for the Ears

An ear thermometer is a useful option for pets that refuse to have their temperature taken through the rectum. This form of thermometer is typically more expensive than a rectal thermometer, but for many owners with fearful pets, it is well worth the investment.

To use this thermometer correctly, pull the ear out slightly and push the tip into the ear canal towards the opposite jaw. For some pets, this may take some getting accustomed to, but ear thermometers are meant to take a temperature in only a few seconds.

Keep in mind that getting precise readings with this approach may be challenging at first if you aren’t used to measuring your pet’s temperature in this manner.

Thermocouple Infrared Thermometer

The infrared thermometer is a newer form of animal thermometer that monitors the temperature of your pet’s skin without touching it.

These thermometers are also more expensive than typical rectal thermometers, but they are highly beneficial for dogs that do not want anything near their rectums or other body areas.

While there has been recorded success with utilizing these sorts of thermometers in people, this is a very new way of taking an animal’s temperature, and it might vary greatly depending on the location of the body you’re attempting to utilize.

These thermometers normally function better on less hairy regions of your dog, such as the inside of their ear or their abdomen.


Because of its flexible tip, LCD screen, and extended battery life, the Vet-Temp Rapid Flexible Digital Dog & Cat Thermometer is the finest overall dog thermometer on our list.

The Vet-Temp Rapid Digital Dog & Cat Thermometer is our top value pick for pet owners searching for a firm tip since it takes your pet’s temperature in less than 15 seconds and reads it in either Fahrenheit or Celsius.

Our top pick is the Pet-Temp Instant Pet Ear Thermometer, which provides comfortable ear canal readings for pets who dislike having their temperatures taken in the rectum.

BestForPets (bestforpets.org) hopes that our evaluations of the best dog thermometers will assist you in making the best decision for you and your canine friend.
