* Affection: Wolves often lick each other as a way to show affection. This is most commonly seen between a mother wolf and her pups, but it can also be seen between adult wolves in a pack.
* Grooming: Wolves also lick each other to groom each other. This helps to keep their fur clean and free of parasites. Wolves will often spend hours grooming each other, and it is an important part of their social bonding.
* Submission or Appeasement: A wolf may also lick another wolf as a sign of submission or appeasement. This is most commonly seen when a lower-ranking wolf is interacting with a higher-ranking wolf. By licking the higher-ranking wolf, the lower-ranking wolf is showing that it recognizes the other wolf's authority and does not pose a threat.
