With my pets and the livestock I have, I have to do my own vet care. I would suggest that if the would is relatively new you bathe with and warm Betadine antiseptic wash to soften the surface of the wound and remove any scab. If you have any peroxide 3% in your medicine cupboard and an eyedropper wash out the wound, if there is any infection the peroxide will fizz white but don't worry as it doing the job. You may have to it a second time. I have treated cuts and abscess caused by barb wire on my self and also the animals.I have never had any problems. Hope this may help
