Whats wrong with a fugging lab or a border collie?
Sheesh.....
No, no....I want some stupid, obscure breed of unknown health and temperament.
Stupid they're not, in fact I've found ours to be much more intelligent than many other breeds, but then that can be a problem. When you give them a command, they don't just say OK they ask "Why?" and you better have a compelling reason "why"
. But not force or negative BS, they doesn't work well with that.
