2- Licks You
While you might not always want your dog to cover you in slobbery kisses, his licks are actually his way of showing affection. Plus, your dog has probably figured out that licking you tends to get your attention. Of course, there are other reasons dogs lick you. Some researchers say licking is a sensory tool for dogs — similar to reaching out and touching something. Another explanation could be that canine mothers lick their puppies (and puppies lick their mothers and littermates) for grooming and social reasons. So this natural behavior continues into adulthood.
