Dogs Have a Slightly Higher Body Temperature Than Humans. Dogs have a body temperature ranging between 38°C and 39°C. If the temperature falls outside of this range, it could indicate health issues such as fever or hypothermia.

Optimal Temperature

The optimal outdoor temperature for dogs is usually between 15°C and 25°C, while the ideal indoor temperature is between 15°C and 20°C. Good to know: despite their fur, dogs can get cold relatively easily. Dogs with a thin coat, in particular, feel the cold faster than those with thick fur. However, the size of the dog is often a better indicator of sensitivity to cold.

Small Dog? Colder Faster.

In general, smaller dogs are less tolerant of the cold compared to larger dogs. Small dogs can experience issues starting from about 8°C. Large dogs can often handle colder temperatures well but should be monitored from about 3°C. Medium-sized dogs fall somewhere in between. Dogs with thin coats, such as Chihuahuas or slim breeds like Whippets, feel the cold more quickly. Those trendy dog jackets aren’t just fashion items! Puppies, sick dogs, and older dogs are also more susceptible to the cold and should be carefully monitored.

Indoor Temperature

The ideal indoor temperature for dogs is usually between 15°C and 20°C. At night, avoid letting the temperature drop too low in the rooms where your dog sleeps, particularly below 10°C. Even with fur, dogs can feel cold. For dogs that are more prone to getting cold, or for small breeds, a heated dog bed or blanket can be a good solution. The temperatures mentioned here are averages, so your dog’s specific needs might vary. Make sure you know how to recognize whether your dog is too cold or too warm.

Is Your Dog Cold?

The following signs indicate that a dog is cold:

• Shivering or trembling
• Curling up tightly to retain warmth
• Seeking out warm spots
• Difficulty breathing
• A weak heartbeat
• Avoiding contact or not wanting to play
• Cold ears or paws

Is Your Dog Too Warm?

The following signs indicate that a dog is (too) warm:

• Panting and restless behavior
• Rapid breathing and drooling
• Seeking out cool places, such as shade or tiled floors
• Loss of appetite and lethargy

Note:

Dogs are more sensitive to heat than humans, so ensure that the indoor temperature is cool enough for them to sleep comfortably.
