As a pet parent, you naturally want to keep your dog healthy, happy, and comfortable. One important aspect of monitoring your dog’s health is knowing what their normal body temperature should be. While you might feel your pup's warm belly when snuggling, it’s not always easy to tell if they’re running a fever or simply feeling cozy. In this guide, we’ll dive deep into everything you need to know about your dog’s body temperature—what’s normal, how to check it, and what to do if it’s not in the safe range. We'll also tackle some frequently asked questions to give you all the tools you need to be the best pet parent possible.

What is the Normal Temperature for Dogs?

A dog’s normal body temperature typically falls between 99.5°F and 102.5°F (37.5°C to 39.2°C). However, much like people, dogs can have slight variations in their baseline temperature depending on factors such as size, breed, and age. For example, smaller breeds tend to have slightly higher body temperatures than larger breeds due to their faster metabolism.

Tip for Pet Parents: It’s a good idea to know what’s “normal” for your specific dog. Regularly checking their temperature can give you a baseline that helps you identify when something is off. It’s also important to note that smaller breeds tend to have slightly higher body temperatures than larger breeds, due to their faster metabolism. If you have a small dog, don’t be alarmed if their temperature hits the upper end of the spectrum. Likewise, a slightly lower temperature in a large dog may not automatically be a sign of illness.

Signs of Fever in Dogs

Recognizing when your dog might have a fever can help you take quick action. While dogs don’t sweat as we do, there are still clear signs that they might be running a temperature. Here are some common symptoms to watch for:

1. Warm or hot ears and paws

2. Lethargy or unusual tiredness

3. Loss of appetite

4. Shivering or trembling

5. Coughing, sneezing, or nasal discharge

If your dog is showing one or more of these signs, it’s time to measure their temperature.

How to Measure Your Dog’s Temperature

There are several ways to take your dog’s temperature, but not all methods are created equal. Some are more accurate than others, and comfort for both you and your dog should be considered. Here’s a breakdown of the best options:

1. Rectal Thermometer (Most Accurate)

This is by far the most reliable way to get an accurate reading of your dog’s internal temperature. You’ll need a digital rectal thermometer specifically made for pets, as they’re designed to be more comfortable for your dog. While the idea might seem uncomfortable, it’s quick and effective.

Pro Tip: Always use a water-based lubricant and insert the thermometer about an inch into the rectum. It’s helpful to have someone assist in holding your dog still while you perform this task.

2. Aural (Ear) Thermometer

For dogs that are more sensitive or anxious about rectal thermometers, an aural thermometer might be a better option. This thermometer is placed inside the ear canal and can provide a fairly accurate reading if positioned correctly. However, ear infections or excessive earwax can affect the accuracy.

Important: Make sure you angle the thermometer into the canal and follow the manufacturer’s instructions for the most reliable results.

3. Axillary (Underarm) Thermometer

While not as accurate as rectal or ear methods, you can use an underarm thermometer in a pinch. Simply place the thermometer under your dog’s armpit and add about 1-2°F to the reading to estimate their core temperature. This is a good option for especially squirmy or nervous dogs.

Note: This method should only be used if other methods are not available.

What Should You Do if Your Dog’s Temperature Is Abnormal?

If your dog’s temperature is outside the normal range, it’s important to take action promptly. A body temperature below 99.5°F or above 104°F can be a sign of a serious issue. Here’s what to do depending on whether your dog’s temperature is too high or too low:

1. High Temperature (Fever)

If your dog’s temperature exceeds 103°F, they’re likely running a fever. Fevers often indicate that your dog’s body is fighting off an infection or illness. At home, you can try the following:

• Offer cool water to help lower their body temperature.
• Wet a towel with cool water and place it on their belly or paws.
• Move your dog to a cooler environment, especially if they are outside in the heat.

If the temperature hits 104°F or higher, immediate veterinary attention is needed. High temperatures can lead to heatstroke, especially in brachycephalic breeds (like Bulldogs), which have more difficulty cooling down. Be cautious not to cool them down too quickly—this can cause shock. Always consult your vet if your dog’s fever persists.

2. Low Temperature (Hypothermia)

If your dog’s temperature falls below 99.5°F, they may be experiencing hypothermia, especially if they’ve been in cold environments. Here's what you can do:

• Wrap your dog in blankets or use a heated blanket.
• Offer warm fluids if they’re able to drink.
• Use a warm water bottle (wrapped in a towel) against their belly.

Hypothermia can be particularly dangerous for puppies, older dogs, or small breeds. If their temperature doesn’t start to rise, head to your vet immediately.

When to Take Your Dog to the Vet

Sometimes, home remedies just aren’t enough. Here are some red flags that indicate it’s time to call your veterinarian:

1. A temperature over 104°F or under 99.5°F.

2. Signs of severe distress like vomiting, diarrhea, or difficulty breathing.

3. Your dog’s temperature doesn’t improve after home treatment.

Veterinary care is especially important if your dog has any underlying health conditions or is a brachycephalic breed, which are more prone to temperature regulation issues.

Preventing Temperature Issues in Dogs

Keeping your dog at a healthy temperature is all about prevention. Here are some tips to help you avoid temperature-related issues:

1. Avoid excessive heat exposure: Walk your dog during cooler parts of the day and ensure they always have access to shade and fresh water.

2. Keep them warm in cold weather: Invest in dog jackets or sweaters for colder climates, and avoid prolonged exposure to freezing temperatures.

3. Monitor for signs of illness: Regular vet checkups and keeping an eye on your dog’s behavior can help catch temperature issues before they escalate.

FAQs 

1. Can I use a human thermometer to take my dog’s temperature?

While you can technically use a digital human thermometer rectally, it’s best to use one specifically designed for pets for comfort and accuracy.

2. What should I do if my dog won’t let me take their temperature?

If your dog is anxious or uncooperative, try calming them with treats or soothing words. You may need a second person to assist. If that doesn’t work, contact your vet.

3. Is a slightly elevated temperature always a cause for concern?

Not necessarily. A temperature of 102.5°F, for example, may be normal if your dog just finished playing or running. But anything consistently above 103°F should be checked out.

4. Can a dog’s temperature change throughout the day?

Yes, just like humans, dogs can have slight fluctuations in their temperature due to activity, stress, or external environment. It’s important to get a consistent baseline for your dog.

5. How often should I check my dog’s temperature?

Regular temperature checks aren’t usually necessary unless your dog is sick or recovering from an illness. In such cases, follow your vet’s advice on how often to monitor their temperature.

Final Thoughts

As a loving pet parent, staying informed about your dog’s health is one of the best things you can do for them. Knowing their normal body temperature and being able to recognize signs of fever or hypothermia will help you act quickly in case of an emergency. Remember, if your dog’s temperature ever concerns you, don’t hesitate to contact your veterinarian for guidance. Monitoring their temperature is just one way to keep your furry friend happy, healthy, and ready for all those cuddle sessions.
