what always puzzled me is the separation and the different way things went between when the dogs arrived in the USA and how different it went with what was left in the UK and Ireland

where in fact the gamedog evolved to become the apbt and what little was left in Europe between 1900 and 1970
although I read a fascinating story about an indian or half indian fella that was stationed in the UK and exchanged dogs briefly with some people
also some staffs were send over in the late 70's
think it had a lot to do with the potato famine but not sure
