    How dogs regulate their body temperature?

    Articledog health and wellbeingThursday 16 June 2011

    The normal body temperature for a dog is between 100.5°F to 102.5°F (38°C to 39.2°C). Body temperature over 104°F or under 99°F indicates an emergency situation and you should contact the veterinary immediately.

    It is used to said that dogs do not sweat. They do sweat, mainly through the footpads. However, only a small fraction of a dog's excess heat is lost this way. Dogs regulate their body temperature through panting. How does it works? The cooling air is moved over the moist surfaces of the tongue and lungs, rejecting heat to the air.

    Dogs also possess a rete mirabile which is a complex of intermingled small arteries and veins in the carotid sinus at the base of their neck. It serves to thermally isolate the head and brain. The rete mirabile allows dogs to sustain intense physical exertion over a prolonged time in a hot enviornment.
