The program also features the sad story of Tom, 32, a theater technician from Tring, Hertforshire, who split up with his fiancee Rachel because of his yearning to dress up as a Dalmatian. He says: 'You disappear and start chasing puppy toys. You go so deep into the head space, you crave it and want it. It's just magic.' 'I didn't understand it. I didn't want to understand it,' says Rachel, who remains friends with Tom.
