Does dog saliva heal wounds faster?

dogs saliva has enzymes that destroys harmful bacteria but also when a dog licks its wound its tongue gets rid of dead tissue so the wounds heal faster.

This may not have the same effect for people. All animals have certain naturally occurring bacteria that live in their mouths. These same bacteria infecting your wound would likely lead to a serious medical problem. If you want to experiment with bodily fluids on your own wound, try your own tears rather than some butt-licking, carrion-eating animal's saliva.
