It’s not only helpful but also a little intimate and relatively easy with the best dog thermometer.

Why and when we need a dog thermometer

Every pet owner must have the best dog thermometer in their pet first aid kit.

Knowing how to tell if dog has fever without thermometer is very difficult and won’t give you an accurate measurement. The same can be said about measuring your dog’s temperature in case of a heat stroke.

Fever in dogs is the most common reason pet owners will have to take dog’s temperature. Symptoms of a dog having a fever are very vague and could be a sign of many different underlying health conditions. That’s why it’s so important to take pet’s temp accurately.

If one or more of these symptoms is accompanied by a fever, it may be an indication that something serious is going on. You’ll need to seek veterinary care immediately.

Temperature of the environment is very important for your dog and for accurately assessing your pet’s condition. I recommend you read a short science-based guide on dog temperatures from Purdue University (the PDF can be found here).

How to take dog’s temperature using a thermometer?

Once you have a rectal pet thermometer for dogs on hand, the process is easy:


Many dog owners don’t realize that their pet’s normal temperature is not the same as that of a human. The normal body temperature of a dog is between 101° and 102.5° Fahrenheit. Therefore, a temperature over 103° F is considered feverish. For more tips and information on this, you can read our full guide on taking a dog’s temperature here.
