Why do dogs lick us? - in detail
Dogs lick their human companions for a variety of reasons, each of which offers valuable insights into the canine psyche and their relationship with humans.
Firstly, dogs use licking as a form of communication. In the wild, wolves lick the muzzles of pack members to signal submission and to reinforce social bonds. This behavior has been carried over into domesticated dogs, making it a key method through which they express their affection, loyalty, and submissiveness towards humans. When a dog licks you, it is often an indication that it trusts and respects you as part of its "pack."
Secondly, licking can be a means for dogs to show gratitude or appreciation. If a dog has just been fed, taken for a walk, or given a treat, it may lick your hand or face as a way of saying thank you. This behavior is particularly common in dogs that have formed strong bonds with their human caregivers and view them as providers and protectors.
Thirdly, dogs may lick humans to seek attention or reassurance. If a dog feels anxious or uncertain about a situation, it might lick its owner as a way of seeking comfort and validation. This behavior is often accompanied by other submissive gestures such as rolling onto the back or avoiding eye contact.
Fourthly, dogs have highly sensitive noses that can detect subtle changes in human chemistry. When humans experience stress, excitement, or other strong emotions, our bodies release hormones and pheromones that dogs can pick up on through scent. Licking is one way for a dog to explore these chemical signals more closely, allowing them to better understand and respond to our emotional states.
Lastly, some dogs may lick humans out of habit or as a form of playful interaction. Puppies especially tend to explore their environment with their mouths, including any available human body parts. This behavior can become ingrained over time, leading to persistent licking even in adult dogs.
In summary, the act of dogs licking humans is multifaceted and deeply rooted in their natural instincts and social behaviors. By understanding the reasons behind this action, we gain a deeper appreciation for the complex nature of human-canine relationships and the profound ways in which our pets communicate with us.
