* Bacteria: Dogs' mouths are full of bacteria, even if they seem clean. While some bacteria are helpful for healing, many can cause infections, especially in open wounds.
* Contamination: Licking can introduce dirt, debris, and other contaminants into the wound, increasing the risk of infection.
* Irritation: Saliva can irritate the wound, slowing down the healing process.
* Spread of disease: Licking can spread diseases between dogs, especially if the wound is infected.
* Behavioral issues: Licking can become a habit that's difficult to break, and it may be perceived as aggression by the other dog.
What to do instead:
* Clean the wound: If you see a wound, clean it gently with saline solution or a mild antiseptic.
* Keep it covered: Use a sterile bandage to protect the wound and prevent licking.
* Consult a vet: If the wound is deep or shows signs of infection, take your dog to the vet for treatment.
In summary: While dogs may lick wounds out of instinct or concern, it's best to discourage this behavior and keep wounds clean and protected.
