The normal temperature of a dog’s body ranges from 101 to 102.5 degrees Fahrenheit, or 38.3 to 39.2 degrees Celsius. If your dog is pregnant and her temperature drops below 100 degrees Fahrenheit or 37.8 degrees Celsius, her labour is imminent and she should normally deliver the whelps within 24 hours.

A type of thermometer is generally classified based on the way used to record the temperature. Make sure to purchase a digital thermometer to get accurate readings, older thermometers are outdated and not very commonly used nowadays.
There are two main categories:
- inserted dog thermometers: these are the ones we insert in a dog’s anus or ear, they have been used forever but they do stress people out and can surprise dogs
- non-touch dog thermometers: these are infrared thermometers that aren’t being inserted anywhere, you aim at the dog’s skin or ear and it records the temperature
Let’s review the different types of dog thermometers and which ones are recommended in which situations.
A rectal thermometer is the most traditional and affordable mercury thermometer. To take your dog’s temperature using the rectal thermometer, you need to be extremely careful. Do check, first, if the thermometer is suitable for dogs or pets.
The preferable approach to check your dog’s temperature using a rectal thermometer is to ask for one more person’s help so that the dog does not make sudden movements. Not all dogs are fully cooperative so here are some recommendations for your next dog temperature reading:
- Shake the thermometer well, bring it to the normal temperature of 96 degrees or less.
- Apply a layer of lubricant such as petroleum jelly to lube the tip, before you put the thermometer inside your dog’s rectum.
- Hold your dog properly and talk to make sure he does not make sudden movements, it affects the reading of the thermometer and can hurt him.
- Prefer a digital plastic thermometer over a glass thermometers (if glass breaks inside your dog’s rectum, it may cause serious injuries.)
Once you are all set…
- Pull up your dog’s tail and slowly insert the tip of thermometer inside his rectum.
- Make sure to only insert the metal-coated tip (putting more inside will harm your dog.)
- Hold the thermometer inside the rectum for 15 to 30 seconds.
- Most digital rectal thermometers available nowadays emit a beep once the reading is taken.
- And if not, you need to check the level of mercury looking at the glass tube of the thermometer
- Slowly pull out the thermometer without letting your dog move.
Clean the thermometer gently using alcohol, wipe it slowly and note the reading somewhere not to forget and to keep track. If the temperature is lower or higher than the normal dog temperature, take your dog to a veterinarian for proper assessment and treatment.
In-ear dog thermometers
In-ear thermometers are super easy to use and a lot less intrusive for dogs than rectal ones. If you find it very difficult to use a rectal thermometer (and don’t worry, most people do), you can also go for a digital in-ear pet thermometer. Often, dogs can react with aggressivity when a thermometer is inserted inside their rectum.
Some of these use infrared heat waves coming out of your dog’s eardrum to record the body temperature with very high accuracy, while other are just like rectal thermometers and use mercury.
First, straighten your dog’s external ear canal by pulling the ear upward and outward slowly. Then, gently put the thermometer inside the dog’s ear canal. Though they are easy to use, they can provide inaccurate readings if you are targeting the wrong part of the ear. Most products are delivered with clear instructions and directions. Some even have a diagram or photo explaining each step.
If you follow proper technique to use the ear thermometer, it provides you with an accurate temperature reading in just one or two seconds. They are amazing!
With technology advancement, non-touch thermometers have become widely popular. Non-touch thermometers mean that there is nothing to insert inside the dog’s ear, mouth or rectum. Everything happens at a distance. Unlike ear thermometers, you don’t have to insert this thermometer inside the ear canal.
Instead, it operates using infrared radiations. These non-touch thermometers are easy to use, faster and very much reliable. However, they tend to be a bit more expensive; generally above the $30 mark. Non-touch thermometers are also recommended for female dog during pregnancy and labour because they are non intrusive and cause no anxiety or stress.
A non-touch thermometer generally comes with the following features:
- An LCD monitor to provide an easy-to-read summary
- A buzzer alarm to announce when the temperature has been taken
- A Celsius and Fahrenheit switch to change the temperature unit
- The batteries and an indicator of charge
There should be no mercury or lead so it’s risk-free for your pooch!
Stick-on thermometers for dogs
These are basically adhesive strips with a temperature ladder printed over them. They are mostly designed in a way that different temperatures show different colors, too. Stick-on thermometers for pets are never used on the animals themselves but rather in kennels, crates, and whelping boxes. They are good at giving a surface’s temperature.
Just pull out the adhesive strip from the back of temperature strip and stick it on the dog’s house to make sure it is not too cold and not too warm. This is a must-have if your female is going to deliver a litter of puppies soon.
