Dogs lick humans for many reasons. One reason is to express affection. Licking is a primary way for dogs to offer comfort, show closeness, and bond with family members. Mother dogs will often lick their puppies, so dogs instinctively learn early on that licking is a sign of affection . Another reason is to get attention or let you know that they're anxious . Studies have shown that licking releases endorphins in a dog’s brain. Endorphins are neurotransmitters that make dogs (and us!) feel calmer and more relaxed .
Sometimes dogs lick because they are bored or anxious. When licking is a self-stimulating activity, it could also be a sign of anxiousness or discomfort . Dogs may also lick you in order to get your attention or let you know that they're anxious .
