Well, 35+ years ago we had a 8 month old Ch. Anton's Harper son. I was new to managing a stud dog, much less a stud puppy. He was loose in the front yard and I let a girl in full bloom run by. Wham! Next think I knew they were tied and he certainly produced puppies. And yes, AKC registered the litter. I would assume if the boy can "do it" , he has viable sperm. VBG!
