While wolves are larger and bulkier, coyotes have bushier tails. Coyotes run with their tails down, while dogs run with their tails up and wolves with their tails straight. Wolves hunt in packs, while coyotes hunt primarily in pairs. A wolf’s call is a sustained howl while a coyote’s rises and falls. Coyotes are more adaptable than wolves and have learned to thrive in human-altered environments.
