15 Best Dog Thermometers of 2023: Rectal, In-ear, Non-Touch, Infrared

Just like humans, pets can get sick. However, they cannot tell you what is wrong. As a pet parent, the obvious thing to do at such a time is to call your vet. But it would help if you try to find out the problem in the meantime.

A dog thermometer is a handy tool for this as it enables you to measure your pooch's temperature. Comparing the results with the normal dog temperature will show if your pet is okay or has a fever. With that in mind, here are the best dog thermometers in the market.

7 Best Dog Thermometers: Review

1. Best Overall: Enji Prime Oral Thermometer

• Type: Rectal
• Celsius or Fahrenheit: Both
• Accuracy: +/- 0.1ºC, 0.2ºF
• Weight: 0.63 oz.

Enji Prime's piece is the best overall and best rectal thermometer for dogs because it is quick, accurate, and waterproof. The tool can give temperature readings in as little as 10 - 30 seconds, after which it gives a soft beep to alert you of the results on the screen.

You can switch between ºC and ºF, depending on your preference. In either setting, the thermometer is highly accurate to within +/- 0.1ºC and 0.2ºF.

After use, the thermometer is easy to clean due to its waterproof exterior. As such, you can wash it with warm soapy water, then wipe it and store it in the included sanitary storage case. A better option is to use probe covers, which help to prevent contamination.

The only disadvantage is that you get only five probe covers. However, these are readily available and you can get a 100-pack set for a reasonable price.

3. Best for Veterinary Applications: ADC 422

• Type: Rectal
• Celsius or Fahrenheit: Both
• Accuracy: +/- 0.1ºC, 0.2ºF
• Weight: 0.8 oz.

Each of these meets the accuracy requirements for intermittent thermometers under ASTM E1112. This assures you of getting reliable results to within +/- 0.1ºC or 0.2ºF.

Apart from that, the thermometer features a specially-designed housing with a lanyard attachment for enhanced removal. A long-lasting 1.55V coin battery provides the required power and it is enough to take up to 1,500 measurements.

On the downside, the unit is very costly but is worth the money.

4. Best Ergonomic: Hurinan Rectal Thermometer

• Type: Rectal
• Celsius or Fahrenheit: Both
• Accuracy: +/- 0.2ºF

With its ergonomic design, Hurinan rectal thermometer is very easy to hold. On top of this, it adds on a small-diameter 3-inch-long probe for easy temperature measurement on any dog size.

The product is recommended for veterinary use and it has a large, easy-to-read 4-digit LCD. This screen shows the temperature measurement to an accuracy of +/- 0.2ºF.

A status function is built-in to indicate when the battery is low. Once this happens, readings are recorded in memory and closed, then the power saving is turned off after 60 seconds.

After use, you can wipe the thermometer with soapy water or alcohol to disinfect the surfaces. That said, a probe cover is not required, but you may use it to prevent contamination.

However, the tool is quite expensive and it does not come with the required 2AAA batteries.

• Celsius or Fahrenheit: Both
• Accuracy: +/- 0.1ºC, 0.2ºF

Also, there is a power-off function that shuts off the thermometer if no action is taken within 10 minutes. This helps to extend the battery life.

On the downside, the tool is not waterproof and you must wipe it with care. Additionally, it has a relatively long reading time of 30 - 60 seconds.

6. Best Quick-Reading: Konquest KDT-1201

With a reading time of only 10 seconds, the Konquest KDT-1201 delivers fast and precise results so that you can detect fevers as quickly as possible. It has a flexible tip that will stay in place during this period to deliver accurate results.

That said, the tip feels soft in the mouth and is very comfortable to use. This section and the entire thermometer are waterproof for easy and thorough cleaning after use.

A fever alarm with three short beeps is built-in to alert you of your pooch's fever if the temperature exceeds 99.8ºF or 37.8ºC.

The only issue is the battery life and even though the duration is not given, some customers complain of receiving brand new thermometers with a low battery.

How to Buy the Best Dog Thermometers

1. Types of Dog Thermometers

Rectal Thermometers

Rectal thermometers have probes that are inserted in the anus, under the tongue, or in the armpit. However, the best spot is in the anus. They are very accurate but can be intrusive, uncomfortable, and messy.

In-Ear Thermometers

As the name suggests, these thermometers have probes that are fitted into a dog's ear canal. They are also very intrusive but deliver accurate results.

Infrared Thermometers

Within infrared thermometers, there are contact and non-touch types. Contact-type thermometers are mostly used in the ear and they have a probe that goes into the ear canal to measure the infrared heat waves. They cause very little discomfort.

On the other hand, non-touch infrared thermometers do not make any contact with your pooch. Simply bring the probe close enough and point it to your dog. They do not cause any discomfort.

Both options are very fast, but costly as well.

Buying Guide: Infrared thermometers have an edge over rectal and in-ear units. They are faster and less intrusive. However, rectal thermometers are highly accurate, which is why we recommend Enji Prime's oral piece .

2. Accuracy

Accuracy shows how correct the thermometer is and the smaller the deviation, the better. Most units have an accuracy of +/- 0.1ºC or +/-0.2ºF. This gives the best results for an accurate diagnosis.

3. Ease of Use

Ultimately, non-touch infrared dog thermometers are the easiest to use as no contact is required. However, with rectal units, ensure they are easy to hold for easy insertion into your pet's anus. This will also help when pulling out the probe.

With that in mind, we recommend Hurinan's rectal thermometer due to its ergonomic, easy-to-hold design.

4. Quick Results

Each thermometer takes a certain amount of time to read the temperature and display results. The shorter the wait time, the better. Most infrared units have a 1-second wait time, which is very impressive.

For rectal thermometers, this is usually longer, but some can be as low as 10 seconds. This can be found in the Konquest KDT-1201 .

5. Study Design

For manual thermometers, you have to lift them to your eye level while holding the stem, not the bulb. They are a bit difficult to read.

On the other hand, digital thermometers are much easier to use. This is because they display the exact reading, so you won't have to approximate the figure. Additionally, some store measurement readings for studying the temperature changes.

Q&A

1. How Do I Take My Dog's Temperature?

This depends on the thermometer. For rectal units, we recommend using probe covers, especially if they are not waterproof. Lubricate this section using petroleum jelly, then gently insert about an inch to the dog's anus.

For infrared thermometers, bring the probe close enough to your pooch to get an accurate reading. In-ear thermometers should be inserted into your dog's ear canal.

2. What is a Normal Dog Temperature Range?

A range of about 99.5ºF - 102.5ºF. This is equivalent to 37.5ºC - 39.2ºC.

3. What Should I Do If My Dog Has an Elevated Temperature?

Excessively high temperatures can damage your pet's internal organs. If you get a reading above 103ºF, seek emergency dog treatment from your vet.

4. Can I Use a Human Thermometer Instead?

Yes. In fact, some thermometers are designed for humans and pets. Just make sure you label the thermometer "for pets use only" as it might be contaminated, especially if it is a rectal type.
