I got home from college and my show bull for this year was a mess. He has some type of bugs, (possibly mites, mange, live, etc.) and has rubbed part of tail head and butt almost raw. He has been sprayed and washed and doing better now but I am looking for tips on how to try to get that hair to grow back. Show is in 3 months and he wil be on a fan soon. Thanks for any and all advice!
