OSW is a gimmick, it was a term used to describe AB's that had no modern AB influence. But now is just another name used for pumping out expensive apperntly pure bred puppies with a mythical history... Aint no such thing, the AB has more breeds in its make up than any other I know lol not saying there isn't any lines of OSW that don't go back 40/50/60 odd years untouched by any other breeds but I doubt it.
Show me a real OSW outworking a full hogdog AB on pigs...
