I would do a betadine bath diluted with water so it looks like tea, just once, and then put her in a sterile bin with paper towel and treat once or twice with non pain relief neosporin. Silver Sulfadaizine is another ointment that you can get from the vet that is much better, it treats gram negative as well as gram positive bacteria and is great for burns. Again, a little goes a long way.

The reason you don't want to do an iodine bath every day is it kills good cells as well as bad ones. So just once to sterilize the area and then ointment sparingly. You don't want to keep any wound damp or wet from ointment for too long, a drying out period is healthy as well as letting oxygen in to the wound.
