"That’s probably okay for a dog who’s been bred  to be a companion animal, but a lot of the bigger breeds and practically all of  the mix breeds were built for work. Having a job to do is a part of their nature;  it’s who they are. The sad thing is, now that hardly anyone makes his living  herding sheep, most dogs are out of a job."
