ok what I did find is that registry and papers do not mean the pup is pur, because the registry only knows what the breeder tells them, pedigree and registry ARE papers so if both can be wrong then I bet they are, border collies just dont get that big, sounds like a barbie collie, but overly large, probibly crossed with a very large dog in its lines, a bernese mountain dog or something, that is just WAY to big for a BC, they are medium sized dogs and 55lbs is already very big double that is giant and definatly NOT border collie size
