When I lived in Canada, old man Farrelly was selling dogs and what not even then. Those dogs were untouched for generations as Jim just bred them and sold them to someone that wanted a dog. He didn't lie about it or try to hide what he didn't do with them. He was honest and upfront.

If you want to just own a dog, then one of those dogs are perfect. If you want some performance dogs, you'd best start looking elsewhere.
