This Morning 's Ben Shephard and Cat Deeley were left in fits of laughter as dog trainer Dr. Scott Miller's canine broke free during a pet segment on the show. The animal expert stopped by to help viewers with their pet problems on today's show, but encountered one of his own when his dog Mango chewed through his own lead and began roaming around the studio. As Dr. Scott prepared to give some tips on a viewer's struggles with their cats, host Ben began laughing as Mango started licking his legs.
