He has tested free for AM (Curley Calf). Dont know if he has been tested for hydro yet. I think E161 in is pedigree is a carrier of hydro. I think they are still devloping the fawn calf test and some others. Hope that helps.
I saw it posted on a different board that he was positive for hydro, but he is not listed on the AAA hydro list. I would call the breeder and find out before using him.
