I spoke with a trainer about Tucker's behavior when seeing other dogs on walks. He constantly barks at them, not sure if in fear or if he just wants to play. I know to try to distract him when this happens, but he doesn't seem to care for the treats we try to distract him with. The trainer recommended using cut-up hot dogs to grab his attention, as they seem to give off a stronger smell than your average treat. I didn't think to ask whether they should be raw or cooked. I'm going to try raw, and see how well it works.
