 is Lady's neighbor, and perhaps the oldest dog in Lady and the Tramp. He was once a police dog working alongside his grandfather, the esteemed Old Reliable, to track down and capture criminals. Eventually his age caught up to him, which is when he supposedly lost his sense of smell for a number of years. Though Trusty firmly believes his strong sense of smell remains intact, Jock believes otherwise (though he refuses to say so, not wanting to hurt Trusty's feelings).
