How old until you expect a pup to bay?

The pups being talked about are out of our Bear and a female that is Ben Jordan blood on both sides but bred by C.W. Brown of Ok. I have nothing to base a comparison on because I don't expect a four month old pup to be anything other than a pup. I may release hogs dragging a stick for them to trail at 7 or 8 months or wait till they are 10 or 11 months old and start them with the old dogs. These dogs produce some very good dogs but they also produce culls. The only reason my dogs and Ben's dogs are talked about is, you never get to see the sorry ones. We cull through them and only keep the very best. I found out a long time ago that average is not very good. You may have two culls, who knows, only time will tell.
