I forgot to mention that Cooper is NOT a pet. Cooper is a working dog. He ought not to be treated as a pet by anyone. In particular, people and young children should NOT be engaging him. They instead ought to be taught that working dogs should never be touched or interfered with EVER. This is why it is so vitally important that he have the vest. A vest is the universally recognised indicator of a working animal and signal that it not be touched. Also, Cooper himself will learn that while wearing the vest he is working. Play and social time should only occur when the vest is removed.
