Okay, so I have this bull calf. He is really good and we're going to show him alot, especially at bigger shows. When we got him, he had all this dead hair. Now, he has no dead hair, but his good, healthy hair is short. The only place he has alot of hair is on his legs and belly. I'm guessing the good leg hair is from me brushing the heck out of it every time he's rinsed and stuff. I do the same on the body. Is there any way that I can promote hair growth all over his body, other than just cold weather and praying? Thanks!!
