Do you remember the one where the German Shepard was out of control because he lacked a task or a job? Cesar found him a pack to wear and the carrying of that pack became the German Shepard's job and he calmed down and was happy from there on out because he had a task and a job to do.
I think of this now as Daddy has passed. He had a great task and fulfilled it very well bringing healing to many dogs (and their parents too :-).
