If seen some horrific looking mutts do well, but if I'm honest most the good dogs I've seen have looked good as well, but these are working dogs, we should never forget that, yeah we all have preferences but they must work, and I personally want the best I cam have, after all I pick it's shit up, o feed it walk it and spend every minute away from me family either sorting them, sorting stuff for them or grafting them, I doubt my dogs care what I look like as I give them graft, as long as they graft to the best of there ability then I don't care if they look like bin tipping 3rd world mongrels,
