Graeme Hall meets labradoodle Hughie, who has a dirty obsession with poo, which is causing owner Trish a lot of embarrassment. The trainer also encounters one of the most destructive dogs he's ever seen. Ziggy has been ransacking owner Richard's house for the best part of 18 months - every sofa is fair game, soft furnishings are on borrowed time and the garden looks like a bomb site.
