Haha! I knew I was going to get that question! Yes I do, which is why I wont be breeding him. He is N/H. Now personally, I don't have a problem with em, my grandmother loved Impressive horses back in the Day, she's owned 11 N/H & we never had a episode with any. However, I know people do- & I would not want to have one bred that someone else would get & then have them not feed/exercise/supplement like we do & have an episode. Plus, I just like him- not the fact he's a stallion. Supposedly, his baby's have all been negative, (the one I have is Neg) but not worth the risk :) People have asked lately, but just not what I want from him.
