why are dogs toungs so long?

Answer 1

If dogs are feeling hot, they cool their body by letting the tongue hanging out and moving it - the evaporation of spittle is cooling.

So if the tongue was too small, the effect would be minimal.

Answer 2

Have you ever held your hand in front of a panting dog's mouth? Whew -- dog breath is hot! What you feel is excess heat leaving the dog's body.

An overheated dog breathes in and out through its mouth. With each pant, dogs inhale cool air. As the cool air moves into the lungs, it absorbs heat and moisture. When dogs exhale hot breath across a wet tongue, water evaporates, cooling their bodies. To maximize heat loss, panting dogs direct warm blood to their tongue to be cooled. The hot, moist air the dog exhales is some 10°F warmer than if it exited the nose, helping to rapidly dump body heat. But just like sweating, panting cools by evaporation, and a panting dog needs access to plenty of drinking water.

Answer 3

It's long so they can clean those places we wouldn't want to stick our tongues and also because it's one of the main ways they cool themselves.

Answer 4

their tongues are long because they need to sweat through their tongues, because they dont sweat through the rest of their body. It is an interesting thing though.
