Dogs pant during summer because, it is very hot so their tongues become dry. to avoid this they pant, when their tongues exposed to air, evaporation takes place.as evaporation is a cooling process they feel cool.

Dogs pant during hot summer days by sticking out their tongues.By this method their tongue is exposed to air.This results in greater evaporation which produces a cooling effect.
