Why does my dog lick my earlobes?FamilyPet
Dogs use licking to show affection, both to other animals and to humans. Licking and grooming another dog, particularly one of their own pack or litter, is a way to show acceptance and love. Dogs are shown from an early age that cleaning and licking one another is acceptable behavior from both their mothers as well as the rest of the litter. If your dog is licking your earlobes, he is most likely doing so in order to show affection.
Dogs also lick because this is one of the ways that they communicate. Since dogs cannot talk, they have to use their paws and mouth to get a message across. A dog licking earlobes could be seeking attention or affection from you, just as he might be showing affection with the licking action.
In the wild, animals spend hours grooming each other to take care of their pack. Dogs who try to lick and groom their human owners are mimicking this same behavior. Although the licking can be annoying at times, or you may think that the licking is unsanitary, your dog sees it as a means to bond and show you love.
