We’ve put together reviews of some of the top thermometers for dogs. Whether you’re looking for a waterproof, infrared, digital, or non-invasive model for small dogs or large dogs, we have you covered. So, continue reading to discover our top picks, including our selection for the best overall dog thermometer.

Verified Review: Our Hands-On Experience

We tested and review numerous dog thermometers. After our extensive testing, we selected the three thermometers below to represent our top picks. Here are a few other noteworthy items about each of these thermometers:

  • iProven Pet Thermometer: We were very happy with how easy this thermometer was to use on our dogs. The flexible tip helped with inserting the thermometer and the waterproof design made clean up quick and easy. However, for some of our dogs that 20 to 30 seconds wait time was too long, and it was difficult to get them to stay still.
  • Pet-Temp Instant Ear Thermometer: We absolutely love how quick and easy this thermometer is to use. Getting a temperature reading after just one second made our dogs so much more willing to have their temperature checked. However, we don’t like that it has an internal battery, and you’ll need to send it back to the company to have it changed.
  • MINDPET-MED Clinical Pet Thermometer: This thermometer was great for our dogs who don’t like to be touched, even in their ears. However, we noticed that the readings were not always very consistent, even when we tested the same dog a few times right in a row.

How Do I Choose the Best Thermometer for My Dog?

When you’re looking for the best overall thermometer for your dog, there are a few different considerations to keep in mind. Weighing these considerations and deciding what is most important to you before shopping will help ensure that you are happy with the product you decide to purchase.

Type

The first thing you need to do is to decide which type of thermometer is you’d prefer. The three main types, as shared above, are rectal thermometers, digital ear thermometers, and infrared/no-contact thermometers. The right type for you will largely depend on your comfort level with taking your dog’s thermometer and their willingness to cooperate with you. Rectal thermometers can deliver the most accurate temperature readings, but infrared/no contact and ear thermometers are non-invasive options that your dog may prefer.

You may also want to consider your dog’s size when deciding which thermometer to buy, as some may be better suited for small dogs than others.

Accuracy

Next, consider the accuracy of each thermometer you are prospecting. As we’ve shared, rectal thermometers are generally the most accurate. However, there will be some variability between different brands as well, so be sure to look for a high-quality product from a trust company.

Additional Features

As you compare the various dog thermometers out there, you’ll notice that some offer different features that can make them easier to use or a better choice for your specific needs. Some of these features you may want to be on the lookout for include: digital displays, flexible tips (for rectal thermometers), instant or very quick readings, the ability to save your dog’s temperature history/the most recent readings, resistant against breaking, the ability to use disposable cover, and whether the thermometer is waterproof and easy to clean.

Budget

Finally, don’t forget to also keep your budget in mind as you shop. You should always look for a good and accurate thermometer for your dog, but you also don’t want to choose one that you really can’t afford or that costs more than you were looking to spend.

The 3 Best Dog Thermometers: Reviewed for 2022 FAQs (Frequently Asked Questions) 

What is a normal temperature for a dog?

The normal temperature for a dog is between 101- and 102.5-degrees Fahrenheit.

How do you take a dog’s temperature?

The steps to take your dog’s temperature will vary based on the type of thermometer you are using.

To take a temperature using a rectal thermometer, start by lubricating the probe using petroleum jelly. Then, while your dog is being held or distracted by someone else, slowly push the thermometer into the rectum. For small dogs, you should push it in about one inch. And for larger dogs, you should aim to push it in between two and three inches. Keep your dog distracted and don’t continue pushing if their muscles feel too tight, as it could lead to an injury or feel painful. Leave the thermometer inserted for about two minutes, then remove it to read their temperature.

To use a digital ear thermometer, start by replacing the probe cover, and then put the thermometer in their horizontal ear canal. Try to keep the thermometer’s base at about a 90-degree angle. For most dogs, this shouldn’t feel too invasive, and they likely won’t struggle or move around. However, if your dog tries to pull their head and ear away, it could be an indication that they have an ear infection. Plus, the reading you get likely won’t be accurate if they have an ear infection.

What should you do if your dog has a fever?

If you think your dog has a fever, start by confirming and rechecking their temperature. This will make sure that the temperature reading you got was accurate. If your dog’s temperature is higher than 104 degrees Fahrenheit or lower than 99 degrees Fahrenheit, it is considered in the emergency range, and you should bring your them to the vet right away.

If their temperature is just a little high or a little low, you should be able to manage it at home. For dogs who have a slight fever, you can try to cool them down by placing cool and damp cloths on their paws. You should also provide cool water to drink and may want to offer some ice chips.

If your pup’s temperature is a bit low, try to warm them up using towels or blankets. Should your dog’s temperature remain abnormal for more than a day, contact your veterinarian and see if they’d like you to bring them in for a checkup.

What are common causes for fevers in dogs?

Just as humans can have a fever for a number of reasons, the same is true for dogs. Below are some of the possible reasons why your dog has a fever:
• Viral or bacterial infection
• Urinary tract infection
• Infection
• Respiratory infection
• Heat stroke
• Pancreatitis
• Cancer
• Tick-borne illness
• Recent vaccination
