Dogs lick humans as a sign of affection and submission. This behavior is rooted in their natural instincts from puppyhood, where mothers would lick their pups to groom and show care.
Why does the dog kiss a person? - in detail
The act of a dog "kissing" a human, often referred to as licking or giving a "wet willie," is a common behavior observed in canines. This action is not merely a display of affection but rather a complex communication method rooted in their evolutionary history and social structure.
Dogs are descended from wolves, and in wolf packs, the alpha male and female often lick the muzzles of younger wolves to stimulate regurgitation. This behavior ensures that the young receive enough nourishment, particularly during times of scarcity. Domestic dogs have inherited this instinct, which is why they may lick your face or hands—a behavior that can be misinterpreted as a human-like kiss.
Moreover, dogs use licking as a means of social bonding and dominance hierarchy establishment. When a dog licks another dog or a human, it releases endorphins in both the licker and the recipient, creating a sense of calm and well-being. This chemical reaction is similar to the "runner's high" experienced by humans during intense physical activity.
Another significant aspect of this behavior is that dogs have scent glands on their paws and in their mouths. When they lick you, they are essentially marking you with their scent, claiming you as part of their pack or territory. This action serves to reinforce social bonds and can be seen as an expression of love and loyalty from your canine companion.
Furthermore, dogs are highly attuned to human emotions and can sense when their owners are feeling stressed or anxious. Licking is often a way for the dog to comfort and soothe its human, providing emotional support during difficult times. This instinctual behavior is deeply ingrained in their nature and serves as a form of non-verbal communication that strengthens the bond between humans and their pets.
In conclusion, when a dog "kisses" a person, it is not merely an affectionate gesture but rather a sophisticated means of communication, social bonding, and emotional support rooted in their ancestral heritage. Understanding this behavior allows us to appreciate the depth of the human-canine relationship and the profound ways in which dogs express their love and loyalty.
