When it comes to keeping our canine pals healthy, one of the most important tools a pet parent can have is a reliable dog thermometer. Monitoring your dog’s temperature can help you detect fever and other health issues early on, making it easier to seek timely veterinary care.
As a veterinary assistant with over a decade of experience, I’ve seen firsthand how knowing your dog’s normal temperature can make a world of difference. Whether you’re a seasoned dog owner or a first-time pet parent, understanding how to take and interpret your dog’s temperature is essential for their well-being. In this guide, we’ll explore the best dog thermometers on the market, helping you choose the right one for your pup’s health needs.
What is a normal temperature for dogs?
Before running off to check your pup’s temperature, it’s essential to learn what’s normal and what isn’t. Unlike humans, whose body temperature usually runs around 98.6°F, a dog’s normal range is between 99°F and 103°F.
Anything higher or lower than that warrants a call to your vet. A fever can alert you to infections, while a low temperature could signal anemia (low red blood cells) and other health issues. Knowing how to accurately check your dog’s temperature can help you assess their condition more effectively.
How to take your dog’s temperature
To get the most accurate reading, rectal thermometers are the gold standard for dogs. Rectal thermometers offer fast and professional-grade accuracy, making them a go-to for dog owners and veterinary professionals. While it may not be glamorous, this method allows you to get the most accurate reading of your dog’s internal temperature. Here’s a quick guide to help you through the process:
1. Gather your supplies
Have your thermometer, lubricant (like petroleum jelly), and a towel ready. Also, be ready to take your dog outside to use the bathroom as taking a rectal temperature can encourage them to have a bowel movement.
2. Prepare your dog
It’s best to have someone help you by holding your dog still. You can also comfort your pup with gentle strokes or by giving them their favorite treat.
3. Lubricate the thermometer
Apply a small amount of lubricant to the thermometer’s tip.
4. Insert the thermometer
Gently lift your dog’s tail and insert the thermometer about one inch for smaller dogs and two inches for larger breeds. Hold it in place until it beeps. Remember — your dog probably won’t like this procedure very much. Watch for signs of distress and don’t get bitten in the process.
5. Read the temperature
Remove the thermometer and note the reading, cleaning it thoroughly afterward. Most veterinary clinics clean the thermometer tip with rubbing alcohol, but you can purchase one-time-use thermometer covers to keep your tool clean and free of debris.
Top dog thermometer picks
I’ve used many thermometers for dogs (and cats) over the years. Here are my top picks for each category: rectal, ear, and non-contact.
Best rectal thermometer for dogs
Vicks ComfortFlex Thermometer. The Vicks ComfortFlex Thermometer has been my go-to for over 13 years. Its flexible tip makes it safer for rectal use, and the 8-second reading is quick and accurate, often finishing before the dog even knows what’s happening. At an average price of $ 14 with a replaceable battery, it’s both affordable and reliable.
Best ear thermometer for dogs
iCare-Pet Dog Ear Thermometer. If taking a rectal temperature isn’t going to happen, you can settle for an in-the-ear temperature. The iCare-Pet Dog Ear Thermometer offers a reading in just 1 second, although accuracy depends on proper technique.
Calm your dog beforehand and clean the ear with a dry cloth. Its shorter probe reduces the risk of ear canal damage, but care is still needed when inserting it. For sensitive dogs, turn off the beeping function. At around $ 30, this is a convenient alternative for those uncomfortable with rectal thermometers.
Best non-contact thermometer for dogs
None (with a caveat). I know this might be a bit disappointing, but I’ve never found a non-contact thermometer that works well for dogs. Because dogs are covered in fur, readings taken from their skin tend to be inaccurate. While some pet owners may use these devices by aiming them at their dog’s belly or the inside of the ear, I wouldn’t rely on non-contact thermometers for precise results. Rectal and ear thermometers remain the gold standards for accuracy.
That said, non-contact thermometers can still be useful in other ways. For example, you can use one to check the temperature of your dog’s sleeping area, bedding, or the surrounding environment.
This can be helpful, especially on hot summer days or during colder winter months when maintaining a comfortable temperature for your pet is important. While not ideal for checking your dog’s body temperature, these devices are handy for monitoring their surroundings.
What to do if your dog has a fever
If you suspect your dog has a fever, the first step is to take their temperature accurately. If it’s above 103°F, you should consult your veterinarian. While some fevers can be managed at home, others may require immediate medical attention.
If your dog’s fever reaches 105°F or higher, don’t wait — head to your vet or the nearest emergency veterinary clinic right away. A fever this high can cause serious health complications and needs urgent care.
For fevers that your vet advises you to manage at home, you can help lower your dog’s temperature by providing cool water baths or placing ice packs on their paws and ears. Be sure to monitor their temperature regularly during this time.
The highs and lows of checking your dog’s temperature
Keeping a dog thermometer on hand is a smart choice for any pet parent. While using a rectal thermometer may seem uncomfortable, it’s the most accurate way to check your pup’s temperature.
Whether you opt for a traditional rectal thermometer or an in-the-ear option, knowing how to monitor your dog’s temperature can help you make informed decisions about their health. With the right tools and knowledge, you can ensure that your pooch stays happy and healthy.
