Well since this ancient thread is already up here, I have a question I've been wondering about regarding breeding age. Is there an approximate age at which a male should be retired from being used for breeding? If, for example, a 10 or 11-year-old male sired a litter, would there be some kind of increased risk of health issues/defects with the puppies, or no?

Thanks for the replies! Ninja's 10.5-year-old grandpa sired a litter that is actually being born right now. I've heard of a few of these older daddies lately, so it just got me curious.
