First off...in the past some people bred for showdogs(including weight pull etc), and others bred for working dogs. Showdog people registered their dogs with Registries that promoted dogs under different names...Staffordshire Bull Terrier, American Staffordshire Terrier, Bull Terrier etc etc., which aimed the bloodlines toward 'standards' based on appearance.
Breeders of working dogs usually had their bloodlines in hand, as their strains were kept more-or-less private, and their 'standards' were based on something different. If you formulated a family that were consistently successful, you had bulldogs..(pit fighting bulldogs) and if they had other registry named dogs(bull terrier, staff, etc) in it, so be it..it didn't matter! because they all originally came down the same pipe and were bred specifically to work.
Personally, I have always liked Psycho and the dogs surrounding him and would have considered myself lucky to have had some in the day. As far as the blue dogs in the ped...(although I don't personally like blue) I like the looks this kennel has put together(however I do not know them)
It is what it is Jim...don't listen to the 3rd party crap..eventually if you really want to know, you will find the source in time.
PS. You used to be able to single register a dog through the ADBA and I'm sure if you fill out the form(below) they might still do it.
