Question

dog generally hang out their tongue in summer why

Answer 1

Dogs have a high body temperature and they hang their tongues out to let heat out through their tongues. Salivating (producing spit or saliva) helps cool the dog when its tongue ishanging out. They have no sweat glands except for on their tongues so they poke their tongue out to cool off.

Answer 2

becoz in summer ,dogs can't bare too much of heat Nd they require more oxygen so they generally hang out their tongue to cool down themselves.
