You’re probably aware that your dog doesn’t sweat to cool off in the same way that humans do. Even if a dog did sweat, their fur wouldn’t allow it to evaporate and cause the cooling effect! Dogs have three main ways of cooling off—learn more here from a Frisco, TX vet.

Panting

Panting is Fido’s primary way to cool himself down. Panting causes moisture to evaporate from the tongue, as well as the nasal passages and lung lining. When the air produced by panting passes over the moist surfaces, your dog is cooled.

Sweat Glands

Although your dog doesn’t sweat the way you do, he does have a few sweat glands. Merocrine glands are located in the paw pads and start functioning when the body temperature rises. They don’t do a whole lot to cool your pup off, though. There are also apocrine glands, which release pheromones.

Vasodilation

Vasodilation means the expansion, or dilation, of blood vessels. In hot weather, blood vessels expand and bring warm blood close to the skin’s surface, where it cools and cycles back to the heart to cool the entire body.
