Dogs lick human wounds primarily as an instinctive behavior rooted in care and, possibly, an attempt to promote healing, although its effectiveness is debatable.
Here's a breakdown of why dogs might engage in this behavior:
-
Showing Care and Affection: The reference states that dogs are loving and compassionate creatures. Licking can be a sign of affection and concern. They might be trying to comfort you and show that they care about your well-being. They view you as part of their pack and are trying to nurture you.
-
Instinctive Cleaning Behavior: The reference mentions that licking is a natural and instinctive behavior for dogs. In the wild, dogs (and their ancestors) would lick wounds to clean them and remove debris, potentially preventing infection. Saliva contains some antibacterial properties (although this is limited). While human saliva also has some of these properties, licking a wound rarely has a significant beneficial effect and can potentially cause more harm.
-
Pain Relief (Possibly): The reference also suggests they might be trying to ease your pain. The act of licking might provide a temporary soothing sensation. The licking might act as a distraction, reducing the focus on the wound itself.
It's important to note that while dogs may have good intentions, licking wounds is not always the best practice for humans. Dog saliva can contain bacteria that could potentially cause infection. It is always best to clean wounds with appropriate antiseptic and cover them with a bandage. If your dog is excessively licking your wounds, consider consulting with a veterinarian or doctor for guidance.
