The dogs are sweating. Sweating is the body’s response to heat when sweat glands release salt water. When water evaporates, it absorbs energy, cooling the body in the process. Although dogs do not sweat as much and look as humans do, they certainly have sweat glands that produce sweat in response to heat. The problem is that most dogs are covered with thick fur, so the sweat hidden in the fur will catch the wool, fail to disappear, and therefore fail to cool the dog too much. Because of this, it is best for dogs to have sweat glands where there is less hair. For this reason, most of a dog’s sweat glands are in the pockets of its feet and on its nose. On a hot day you can see the dog leaving a trail of wet feet as it walks on a smooth and dry surface. That’s a dog’s sweat.
Since there are very few active areas for dogs to get sweat glands that cool the body compared to humans, dogs have to rely on another method to stay cool. The first way to cool the dogs is to breathe. By breathing in air over the wet areas of the mouth and inner lungs, dog trousers accelerate evaporating cooling in the same way that the wind blows on the sweaty skin of a person. Dogs have different types of sweat all over their body. But the sweat released from these glands is used to withstand the rapid rise in temperatures in the skin that can lead to burns, not cooling the whole body.
The Bookbook of Small Animal Surgery, edited by Douglas H. Slatter, states: “Merocrine glands are compact, simple, and glandular glands found mainly in dog tracks; they shed directly on the surface of the skin. on the furry skin of dogs and cats [apocrine glands] do not participate in the central thermoregulatory process but protect the skin from excessive temperature growth. “
