Why do dogs like to kiss on the lips? - in detail

Dogs often engage in behavior that humans interpret as "kissing on the lips," which is primarily rooted in their natural instincts and social behaviors. This behavior can be traced back to their wolf ancestors, where licking the faces of pack members, particularly the alpha, was a sign of submission, respect, and bonding. For dogs, licking is a multifaceted form of communication. When puppies are born, their mothers lick them to stimulate breathing and clean them, creating an early association between licking and care. As dogs grow, they carry this behavior into their interactions with humans, using licking as a way to express affection, seek attention, or show submission. Additionally, dogs have an acute sense of smell and taste, and they are drawn to the salt and food particles often present on human lips. This makes licking an appealing activity for them. From a psychological perspective, dogs are highly social animals that thrive on forming strong bonds with their human companions. Licking releases endorphins in their brains, providing them with a sense of comfort and pleasure. When a dog licks a person’s lips, it may also be seeking reassurance or trying to establish a connection, as this behavior often elicits a positive response from humans, such as petting or verbal praise. Over time, dogs learn that licking is an effective way to interact with and please their owners. It’s important to note that while this behavior is generally harmless, it can sometimes be a sign of anxiety or stress, especially if it becomes excessive. Understanding the underlying reasons for this behavior helps strengthen the bond between dogs and their owners while ensuring the dog’s emotional well-being.
