Butcher Boy s (foundation sire of line BB, pedigree unknown)LINE BB
(Main current line in England; essentially extinct in US)
This is the English root of the BB sire line, showing sire to son descent of all Shelties of the BB line imported to the US and appearing behind ROM Shelties. All dogs in the lineage are males, though some lines terminate with bitches imported to the US or Canada. Note that while Montlethen Blue Prince is still considered officially to be in the BB line, it is generally acknowledged that he was a Collie.
