I've been having the some problem with my dog. I have some abrasions on each knee and she is constantly trying to lick them, she too tries to lick through the bandage. One I've been letting her lick but not the other one and guess what. The one she licks is almost gone. I guess ill be letting her lick both now.
Yes I think they do because my dog always does and it cures... FAST! Hope this helped
Licking for a dog is its way of communicating with its owner that it cares. Dogs also lick themselves and their young ones to keep them clean and cure any wounds. However, some people may believe incorrectly that a dog's saliva is unhygienic. This belief is not always true and in the case of a dog that is otherwise fit its saliva is known to display antibacterial properties. Of course, the dog should be healthy and not suffering from any infectious disease itself, in which case it should be promptly treated before it is allowed to come in close touch with other humans and specially children.
The science magazine Alaska Science Forum has published an article entitled "Dog Saliva: the Next Wonder Drug?" which brought to light an experiment conducted by research students in California discovering that the saliva of a dog is potent enough to kill bacteria like E. coli and streptococcus. Another amazing story about how a dog helped heal his owner's severely atrophied leg appeared on a UK news website.
