Why do dogs pant and hang their tongues out such a lot when wolves (and most animals) do not? Is it a trait that somehow selected for during domestication?

Nearly every warm-blooded animal has some method of thermal regulation, and wolves do indeed pant to stay cool. In fact, wolves are more efficient at panting than most domestic dog breeds because their snout shape and long tongue are the result of evolution rather than selective breeding by humans.

The reason that wolves are not often seen panting is that unlike domestic dogs, wolves tend to find cool spots and relax during the hotter parts of the day. Domestic dogs have developed relationships with humans, and thus they are active whenever humans are active and have more of need to cool themselves.
