Why do dogs pant?

Dogs pant to cool off when they are feeling hot.  When our body temperature gets too high, we sweat.  Evaporation of sweat from the skin takes up a lot of heat, and helps cool the body.  But dogs are almost completely covered with hair, and have every few sweat glands.

They can’t keep cool by sweating.  Instead, a dog pants.  It sticks out its tongue and breathes rapidly.  By panting, a dog moves air back and forth over the moist tissues of its mouth and tongue.  As the moisture evaporates, body heat is carried away, and the dog feels cooler.–Dick Rogers

What is a called blooded animal?

Cold Blooded Animal

Many animals such as fish, frogs, snakes and lizards are often called “cold-blooded,” as opposed to “warm-blooded” mammals and birds.

This does not mean their blood is always cold. Unlike warm-blooded animals, they do not have built-in temperature controls that keep their bodies evenly warmed.

Instead, their body temperature is usually near that of the surrounding air or water air or water.  The cold-blooded animal is hot in hot weather, and cold in cold weather.

Many depend on the sun for their body heat. Lizards, for example bask in the sun to warm their bodies.–Dick Rogers
