I honestly think it depends on the dog. If you go to a breeder that breeds their dogs for working then the dog will more likely more in the mood for work then just hanging around the house and beinging a pet. I know for collies that if you get one that's a little older from a breeder you might be able to request a herding reject, one that hasn't shown any interest in herding what so ever. But I honestly think that even if you get a working dog they can still make good pets just as long as you remember that they still have that drive and desire to work and try to provide for that.
