I think this is a great post also. I enjoy talking about pedigrees, bloodlines, breeding, etc.
Before I started getting registered dogs a few years ago I wouldnt have given a nickel for a pedigree and couldnt have gotten one if I had wanted to. I just wanted a dog that would run rabbits. Id buy a dog or pup from somebody and they might say the male you bought was out of Molly and she was out of Blue and Angel and they were out of so and so but that was about as far as it would go. It sure didnt mean they werent rabbit dogs, it just meant you couldnt really trace their ancestors the way you can with a pedigree.
You mentioned Stubby and Buzzbomb earlier. They were both born in the mid to late seventies but you can still buy "Stubby" and "Buzzbomb" pups today.
I know theyre saying linebred but just for conversation, when do yall consider a dog linebred?
Most of my dogs have Postoak Little Nip Otis in their pedigree but I dont have a single dog that is straight out of him. What I usually consider linebred is when that dog is in the pedigree at least one time on the top and bottom of the pedigree. But using that as a guage, you could call an "Otis" dog a linebred Inline Black Jack (Otis' sire) or it might even be more appropriate to call em linebred Rob's Diamond since he's Otis' grandsire top and bottom.
It can get pretty confusing sometimes.

ullhair:
Another question is when do you consider a line of dogs "your line"?
