there is a powder called ster-zac.its been around for years used when babies umbilical cords are cut.i use it on the kids when they bleed badly.its stops the bleeding, helps the wound to clot.i dont know if its any good for dogs if they lick it off ,may upset them.just make sure it doesnt become a behavioral issue with the dog biting the wound i am stuck with the terrier doing this.started as flea allergy and now she wont stop pulling out coat and making skin bled.
