First, the breeder would probably like some feedback. Second, yes you could supplement him differently to help prevent arthritis if the xrays show HD/ED. Or if you are going to do any sports with him, it's nice to know what his hips/elbows are like.
Or you could just give him joint supplements and skip the xrays unless you see evidence of a problem.
