Pardon me for asking but what difference does a line make? There've been so many bred from those so called lines I doubt the differences are recognizable. Isn't what's important the dog that's in front of you? Gould, Nuttall, Booth, or Captain Kangaroo wouldn't make a rat's ass to me if the dog was what I want, fine. If not, then the Pope could have bred the dog and I still wouldn't have it.
