Normal Dog Temperature Range

The normal dog temperature range typically falls between 99.5°F and 102.5°F (37.5°C and 39.2°C) for adult dogs. This range may vary slightly depending on the dog's breed, size, and individual factors. It's important to note that a dog's temperature can fluctuate throughout the day, usually rising in the evening and dropping during sleep.

Pregnant dogs' temperatures will drop about 24 hours before they go into labor, so taking their body temperature is a good way to prepare for a dog about to give birth.

What is The Normal Dog Temperature for Puppies

Puppy body temperature differs from that of adult dogs, especially during their early development, as research shows many physiological differences between a puppy and an adult. A typical puppy under the age of four weeks will have a lower average body temperature of 95°F - 99°F (35°C - 37.2°C).

But after 4 weeks, their body temperature becomes roughly the same as an adult's.

So, for a 12-week-old puppy, the average body temperature can range from 99.5°F to 102.5°F (37.5°C to 39.2°C). It's crucial to closely monitor a young puppy's temperature, as they are more vulnerable to temperature changes and can be prone to hypothermia or overheating.

Note that this is the average dog's temperature range, and when it reaches 103 to 106°F (39.5 to 41.1°C), your dog probably has a fever. Temperatures of 106°F (41.1°C) or higher are critically dangerous.

For a high body temperature, you may need to dip into a Pet Emergency Fund to get your puppy to a veterinarian immediately. This fund can pay up to $3000 for an emergency vet bill for less than $1 per day.

Puppies can only start regulating their body temperature at 3 weeks, but they are still vulnerable to hot and cold climates until they are at least 2 to 3 months old. So you need to ensure the environmental temperature for newborn puppies is neither too hot nor too cold. Puppies are also in danger of infectious diseases like parvo, which can cause a fever.

Normal Puppy Temperature Chart at Different Ages

Puppy Age Normal Puppy Body Temperature Best Room or Environmental Temperature
1-2 weeks 95°F - 99°F (35°C - 37.2°C) 85 - 90°F (29.4°C - 32°C)
2-4 weeks 97°F - 100°F (6.1°C - 37.8°C) 79 - 84°F (26.1°C - 28.8°C)
5-8 weeks 98°F - 100°F (36.7°C - 37.8°C) 73.5-79°F (23°C - 26.1°C)
8-12 weeks 99°F - 102°F (37.2°C - 38.9°C) 73.5-79°F (23°C - 26.1°C))

Room humidity for young puppies should be between 55 and 60% to help them keep a healthy body temperature. When raising an orphaned newborn puppy, the ideal room temperature is usually higher since the puppy doesn't have its siblings to help keep it warm.

According to veterinary guidelines, the best room temperature for orphan puppies is:

  • One week old: 95°F (35°C) ambient room temperature
  • Two weeks old: 87.8°F (31°C) ambient room temperature
  • Three weeks old: 82.4°F (28°C) ambient room temperature
  • Four weeks old: 72.8°F (26°C) ambient room temperature

How to Take a Dog Body Temperature

You may notice a dog's temperature is too high by feeling their ears. Much like feeling a person's forehead, ears that are hot to the touch are your first sign that a dog may have a fever.

To accurately measure a dog's body temperature, follow these steps:

  1. Choose a reliable rectal or ear thermometer specifically designed for dogs.
  2. Lubricate the rectal thermometer with petroleum jelly or a water-based lubricant.
  3. Gently lift your dog's tail and insert the thermometer into the rectum, about 1 inch for small dogs and 2 inches for larger breeds.
  4. Hold the thermometer in place for approximately 1 minute or until it beeps (if using a digital thermometer).
  5. Remove the thermometer and record the temperature reading.

How Do Dogs Regulate Their Body Temperature


Dogs have several mechanisms to regulate their body temperature. IEEE studies identify these main ways that dogs thermoregulate (control their body heat):

  1. Conduction: When dogs press their bodies or bellies against a cold floor or cool earth under a shady tree, they lose a lot of excess heat through their skin against the cooler surface.
  2. Convection: When dogs stand in a cool breeze or front of a fan, the cooler air moves through their fur and dissipates the heat from their bodies. This is why matted hair in dogs with long hair affects their ability to cool down since air cannot move freely through a matted coat.
  3. Radiation: This refers to how the dog's body gets rid of heat by sending warm blood to the skin and outer points of a dog, like their ears, so that the heat can radiate from and away from their bodies. This is why a dog with a fever or that is overheating will have very warm ears, as the body pumps blood to the ears, mouth, nose, and skin to get rid of heat.
  4. Evaporation: A dog's main means of getting rid of heat is to let moisture evaporate from their mouth when they pant. Dogs also have sweat glands on their paws that allow them to get rid of some heat.

When dogs are cold, they typically regulate their temperature by flattening their coat to prevent convection or staying out of the wind. They will lay in the warmest places to absorb heat and cover their bellies to avoid losing heat through conduction. The blood vessels in their skin and ears will contract, forcing the blood to stay closer to their organs.

Naturally, cold dogs will also not pant unless they are exercising heavily.

To know if your dog is getting too hot or too cold, it's best to invest in a Petcube Camera to keep an eye on them while you are gone. This way, you can look out for behaviors that suggest your dog is struggling with temperatures, such as shivering or excessive panting.


When Can Puppies Regulate Their Body Temperature?

Puppies can start regulating their body temperature independently at around 4 weeks of age as their thermoregulatory mechanisms develop.

How Do Dogs Regulate Their Body Temperature?

Dogs regulate their body temperature by panting, seeking shade, thermoregulating through their paws, and adapting their coats to retain or release heat.

Final thoughts

Understanding the average dog's temperature is essential for every pet owner. By being aware of the normal temperature range for adult dogs and puppies, knowing how to measure a dog's body temperature, and recognizing how dogs regulate their body temperature, you can better monitor your furry friend's well-being. Always consult with a veterinarian if you.
