As for why wolves and dogs do it, there could be multiple reasons. They might be disguising their own scent in order to sneak up on prey, they might want to bring that scent back to the pack to share, or they might even be doing it to make themselves seem more attractive to potential mates! | Brookfield Zoo Chicago | Facebook
