Dogs are homothermic or warm-blooded animals animals.
Their body temperatures are maintained at a fairly constant level regardless to the temperature of their environment. The hypothalamus is the main part of the brain that regulates body temperature. When the body temperature is low, the hypothalamus stimulates the body's muscles to shiver. When the body temperature is high, the hypothalamus will stimulate the sweat glands and stimulate the blood vessels of the skin to allow more heat to escape from the body. Like most animals, dogs are insulated by their fur against heat lost or gain.
