Ever since the puppy, who now goes by the name Tug (Tugger), arrived here at the farm we have been all about motion and rest. He goes. He stops. He goes again. When you have a border collie for a mom, and an Australian shepherd for a dad, there is simply no middle ground.
It is said that when the position of a body with respect to its surroundings changes with time, it is in motion. And Tug has been on the move.
When the position of a body with respect to its surroundings does not changes with time, it is said to be at rest. And when Tug is not on the move, he can give it a rest.
