I couldn't bring myself to go as far as letting a dog lick a wound, but these days the Mayo Clinic is advising against using disinfectants like iodine or alcohol; just make sure it's clean and apply a sterile bandage. Rationale: disinfectants do kill bacteria, but applied to an open wound they also kill white blood cells; apparently it's a net negative.
