Wound licking is an instinctive response in humans and many other animals to an injury.

Dogs, cats, rodents and primates all lick wounds.

There is a common folk belief that animal saliva, especially that of Dogs, has healing properties for human wounds.

The benefits of moderate wound licking:

The enzymes in dog saliva help destroy the cell walls of dangerous bacteria. Lactoferrin and other antibacterial and anti-viral compounds can also be found in saliva. Licking a wound delivers protease inhibitors, and growth factors, which promote wound healing.
