Bones is getting up in age. He has only been bred a limited amount of times due to the fact his sire was being used and we are selective on who we bred any of our dogs to. Bones is worth breeding to on his own merit. However; to answer your concern there are a couple winners out there off of him. His offspring are showing all The good the rb/j/t/b line is known for with surprising ability to complete there task at a high level. He doesn't have many adult offspring out there due to inresponsible owners and a few being held back per there owners. Pm me for additional information. Thanks
