why do dogs lick each other

Dogs lick each other for several reasons, mainly related to social bonding, communication, grooming, and comfort. This behavior helps dogs connect and form bonds, as licking releases oxytocin, a hormone that promotes feelings of safety and connection. Mother dogs lick their puppies to clean and comfort them, and as dogs grow, they continue licking as a way to show love, friendship, and submission. Licking can also serve practical purposes like grooming, especially ears, and checking on the health of other dogs. Additionally, licking can be a way for dogs to communicate feelings such as friendliness, anxiety, or a request for something like food or space. Sometimes licking is soothing and provides comfort, functioning like a calming mechanism. However, excessive licking might indicate stress or medical issues and may need attention. In summary, dogs lick each other to bond socially, groom, communicate, and comfort themselves or others.
