Why do dogs pant?
Dogs pant to cool themselves down. When humans get too hot, they perspire. Water seeps out through our pores and forms a thin layer of moisture over the skin. If we then stand in a breeze, it will cool us down.
As the breeze passes, it evaporates some of the perspiration on our bodies. When water evaporates, it draws heat from its environment. So, as perspiration evaporates from your skin it takes some of the heat out of your body.
Dogs don’t have sweat glands, except between their toes, so they can’t sweat. Instead, they pant. The breeze from the dog’s breath flows over his or her moist tongue and cools the blood that flows through it. And this eventually cools the dog’s whole body.
