Why Does a Dog Hang His Tongue Out?

Answer

A dog hangs his tongue out of the mouth in order to regulate heat as the moisture on the tongue will make the blood flow to be cooler. The tongue will become bigger because of the increase in the flow of blood. A dog will also use its tongue to clean its body and fur.
