Why and when we need a dog thermometer

Best Dog Thermometers for an Accurate Dogs' Temperature ReadingEvery 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.

What Is the Best Dog Thermometer?

1iSnow-Med Non-contact Infrared Pet Thermometer


The first best dog thermometer on the list is the most popular option from iSnow. Most pet owners have that quiet dislike for traditional thermometers that work best only when used for taki`ng rectal temperature. It’s easy to see why! Pets are generally uncooperative when they’re sick, and inserting a thermometer that way upsets them.

Not to mention, glass thermometers could break and expose pets to mercury. If that has long been your dilemma, then this non-contact ear thermometer from iSnow-Med couldn’t come at a more opportune time.

A precision thermometer specially designed for big-eared animals, this gives you the temperature of your pet in a second without need for contact. It is infrared operated. You then have a tool that is more acceptable, especially at a time when your pet is understandably indisposed.

This handy device is calibrated for animals, and is battery operated.

Most users of this pet thermometer have relegated their mercury thermometers to the trash bin because they found out that this reads faster, is more reliable, and is a lot safer.
