Wolves are built to withstand extremely cold temperatures, but summer heat can be a challenge. Wolves (like dogs) will stay cool by panting to evaporate heat and moisture off their tongue. Panting is especially effective for wolves.  A wolf’s elongated muzzle and the shape of the inner nose ensure optimal oxygenation and an efficient cooling system. Wolves also alter their patterns of activity, staying hunkered down during the hottest times of day.
