Hootie got scraped up a bit on his hind lower leg. It was as if he scraped going over a log or something. It wasn't deep and didn't cause any lameness, just took the hide off him. It's been there for months and although it healed quickly with no issues, he can't grow hair there. It looks as if I tried to whack him with a board! There is an area of about 1" wide by 2" long. It's kind of hard like a callous now. Doesn't ever bleed or open up again...just like an old scar.
Any ideas on how I may get hair growing again??
