Have you ever relaxed on the couch only to have your furry companion enthusiastically lick your hands, arm, or face without stopping?

Decoding these subtle signals strengthens your bond with your pet and ensures you respond correctly to their daily needs.
Understanding canine evolution clarifies why licking is such a deeply ingrained instincts in domestic dogs. From the moment puppies are born, their mother licks them to clean their coats, stimulate breathing, and foster a secure emotional bond.
