That was actually a rhetorical question...
I would think it would be obvious that a flushing lab breeder would make darn sure that any breeding stock would meet their (flushing) criteria before breeding.
The fact that a dog has the "AKC" in front of it's name means nothing.
You wouldn't go searching for breeding stock from service dog lines anymore than you would pointing dog lines.

By labeling a "point" as a "soft flush" speaks volumes to your knowledge of pointing dogs. A point is a point....nothing else.
If you have to wait 10 minutes before the final brake and flush, is that considered an "extremely soft flush"? How about 30 minutes? 45?...still just soft?
That's a rhetorical question too... No need to answer.
