Where did you get him from? Is he AKC registered?
You can do a search on pawvillage.com and put the sire and dam's name into the OFFA website...
Orthopedic Foundation for Animals
Also...just because you get his hips and elbows checked..he would also need eyes and heart to be done too, as well as being shown in some type of venue. Either AKC show or Sieger show and he should have some sort of titles.
You need to know his history and his family history (pedigree)...before you even think of using him as a stud.
