Myths About Dog Saliva
Because dog saliva contains a special enzyme which promotes healing of the dog's wound, some pet owners think it will have the same effect on their own cuts.

Facts About Dog Saliva
One potential health risk associated with being licked by your dog is the transmission of roundworms. These intestinal parasites are commonly found in kittens and puppies and are passed through licking. Symptoms of roundworm are coughing, a fever and headaches. Of course if your dog has been given deworming medication, and is tested on a regular basis, your risk of contracting roundworm is slim. Leptospirosis, salmonella and E. coli are other illnesses that can be transmitted by your dog's saliva; contracting rabies from the bite of a rabid dog is also possible.
