what happens if a dog licks a wound
Wound licking It has been long observed that the licking of their wounds by dogs might be beneficial. Indeed, a dog's saliva is bactericidal against the bacteria Escherichia coli and Streptococcus canis, although not against coagulase positive Staphylococcus or Pseudomonas aeruginosa.[33] Wound licking is also important in other animals. Removal of the salivary glands of mice[34] and rats slows wound healing, and communal licking of wounds among rodents accelerates wound healing.[35][36] Communal licking is common in several primate species. In macaques, hair surrounding a wound and any dirt is removed, and the wound is licked, healing without infection.[37]
