[blockquote]when you say his are you refering to Sam or Antonio? How far back does you or his dogs have barnacan bull in their lines? Just asking because I believe after a few generations of breeding if not bred back into the line then they really aren't barnacan bull or whoever line for that matter![/blockquote] Sam=Slamm and Antonio=King Zulu,and also Realpresa from Korea who is working with fedor,king and nidia against 200-250 kilos's boards.I believe you know these dogs! now i beleive you understand who are these gyus pitbull22 ;) i am one of you friend....george :)
