I agree with using saline to clean the wound. A teaspoonful of table salt per quart or liter of water. Bring to a boil, then lower to a simmer for 5 minutes then cool to room temperature. Apply an antibiotic ointment such as plain triple antibiotic or neosporin twice a day. If she is alert, can stand and walk, and is eating and drinking, she should recover. She could be in shock at first, but hopefully she will recover.
