Knowledge popularization

Dog dung contains a lot of information, which is a weapon for adult wolves to mark their territory, but for young wolves, it is no less than a hypnotic spell. Many animals can find traces of wolves from their droppings, such as bears. In order to prevent the smell of wolf cubs from leaking out, father and mother wolf must dispose of the excrement of wolf cubs.

Moreover, in order to keep the wolf pups clean, the mother wolf will lick the wolf pups' buttocks after excretion to prevent the wolf pups from getting sick because of the feces left on their buttocks, so almost every wolf has eaten feces.
