I think you'll do far more damage trying to keep it bandaged than that little scratch will do. If I had a wound like that on my own hand I don't think I'd bother bandaging it. Horses are not made out of cotton candy. They can heal perfectly fine without any help from thier owners most of the time and this is definately one of those times.
There's nothing like the Rockies in the springtime... Nothing like the freedom in the air... And there ain't nothing better than draggin calves to the fire and there's nothing like the smell of burning hair. -Brenn Hill
