Can Dog Drool Kill Germs?
There are many stories about injured hunters or pioneers who recovered from their injuries because wild animals licked their wounds. Such stories are not unique to the American West, but are common to many cultures. For example, the French have a saying “Langue de chien, langue de médecin,” which means “A dog’s tongue is a doctor’s tongue.”
Even in our own modern society, the first thing we do when we get a paper cut is to put our injured fingers into the mouth. Is there any truth to these folktales? If an anti-bacterial effect is not observed, are there other benefits of wound-licking that could encourage healing?
