I'm not a breeder, but if in your shoes, I would have this boy neutered ASAP. If you've bred biewers in the past, and have been keeping accurate records, you'd know if your females lines have produced PDA (sorry, don't know what that is) in the past. You'd know to look for clues in each dam's line, going back a few generations. If that doesn't pinpoint the problem, start looking at the studs lines, and see if any of the dogs in his lines are producing the same problem. That's why an accurate record of breedings and results are needed.

I hope someone more experienced can help with your dilemma.
