Licking can be a sign of affection

Dogs often show affection by licking. It’s an instinctive behaviour that’s linked to the comfort they felt when their mother licked them as a puppy. Licking plays an important part of how they bond with others, causing them to release dopamine and endorphins that help make them feel relaxed, calm and happy. Just as it feels nice for us to stroke a dog, it probably feels nice for dogs to lick the ones they love.
