I love studying that old stuff. It's crazy how much centipede looks like some of these dogs. I have never had dangerous pits that I had or worry about biting me or someone else. Hemphill had that thing where he talked about the temperaments of his dogs. Mine were always like that. My dog off paw paw and my current dogs. I believe redboy had a good amount in him. I have always preferred red over black. One reason I have a hard time leaving these dogs. They are like a history book. Plus never knew there was red in and behind black widow.
