Dogs lick people for several reasons, mostly rooted in instinctive and social behaviors. The main reasons dogs lick you are to show affection , to explore their environment , to get attention , and sometimes because you taste good to them, such as when you have salty sweat or lotion on your skin. Licking also provides dogs a sense of comfort and security, reminiscent of how mother dogs groomed their puppies. Additionally, dogs may lick as a submissive gesture or to communicate with you. In some cases, licking can be a response to stress or anxiety in the dog. This behavior releases feel-good brain chemicals in dogs, helping them feel calm and happy. In summary:

• Affection and bonding: Licking mimics the comfort puppies get from their mother’s licking.
• Exploration and scent: Dogs use licking to taste and smell parts of people, especially hands and face.
• Attention-seeking and communication: Licking often is a way to get your attention or express excitement.
• Taste: Sweat and lotions on your skin can be appealing to dogs.
• Stress relief: Licking can soothe anxious dogs.

Licking is generally a natural and positive behavior, but excessive licking may indicate stress or medical issues, in which case consulting a vet is advised.
