Wash the wound out thoroughley with antiseptic wash, also make sure your hands are sanitised, push the wound together and staple they only just punture the skin and 9 out of 10 dogs wont even flinch, leave them in ten days then take them out with a proper remover, if the wound is in a place where the dog can bite at it put a buster collar on it, if its just a nick from wire or something else in the field I dont usually bother with antibiotics if its from tooth or claw I would use antibiotics. hope this helps
