Aww, if they are lame from scratches it must be a pretty severe case. If you want quick healing, I swear by this, athletes foot spray. You will see healing in a matter of days, not a week. Shave the area, clean the area well and apply spray a few times daily. If they get wet or muddy, try to towel dry them and not clean with water unless absolutely necessary. I have tried many things, this works!!! Don't forget to spray near the horse first to make sure they arent startled by it, don't want an accident.
