Renorey--that was what I thought by your post. They were being judged by breeding only, not by breed standard. Sorry
As far as age. I have known plenty of older sires. My boss has one Mi-Ki that is 13yrs and still producing strong. My Original aussies dad was 14yrs. If AKC puts an age on the sire, I think that is rediculas. If they are willing, able, and have good sperm, why shouldn't they. AI's don't always work, I have lost money on several. I prefer live cover.
