Don't use betadine, use a nolvasan product instead to rinse the wound. Just flushing with warm water is good, and then apply Silvadene, or triple antibiotic ointment if you have that. Make sure that the maggots and fly eggs are all gone, and check her vent area too. Immediately! Gently soak the scab off if there's pus and gunk under it, and then use the ointment. Mary
Do like this says and clean it thoroughly with Nolvasan (chlorhexadine). Peroxide and alcohol are ineffective cleaners. Spend the money and get the Nolvasan. If you can't afford it, get some betadine, but Nolvasan would be *much* better.
