Why does a dog stick its tongue out? There may be several reasons why dogs stick their tongue out:

1. Breathing: Dogs have a high temperature environment or after exercise, and they need to lick or pant to dissipate heat. At this time, they will stick their tongue out.

2. Drinking water: When a dog drinks water, it will lick the water surface with its tongue and then stick its tongue out so that it can swallow the water.

3. Expression of affection: When dogs feel comfortable, relaxed or happy, they will stick their tongue out, which may be a sign of pleasure.

4. Disease: When dogs feel pain, discomfort or dry mouth, they will stick their tongue out, which may be one of the symptoms of the disease. If your dog is sticking his tongue out frequently, take it to the veterinary office for examination to determine any potential health problems.

In short, the dog sticks out his tongue may be for the purpose of dissipating heat, drinking water, pleasure, and diseases. If you observe that your dog frequently sticks out his tongue, you should pay attention to his health and take it for examination in time.

When the weather turns hot, the dog will stick its tongue out to dissipate heat due to the heat.

Mammals are constant temperature animals, and their body temperature is constant in any season. In the hot summer, it is necessary to secrete sweat to dissipate heat and maintain body temperature. Dogs’ sweat glands are concentrated on their tongue and toes, so when heat is needed, they stick out their tongue to increase heat dissipation.

In summer, owners should pay attention to preventing heat from the dog and do not let the dog expose it to the sun under the scorching sun.
