Trevor's mum has offered him £30 to walk the dog every day of the holidays. But Streaker is no ordinary dog, she's a rocket on four legs with a woof attached. Trevor's sure there must be a way to control her and Tina, his best friend, knows about training dogs. Their attempts involving such things as a pair of roller skates, a mobile phone and a bicycle, always lead to trouble. Horrid Charlie Smugg bets Trevor he can't train Streaker before the end of the holidays. But Trevor and Tina constructa dream plan and Charlie has to eat his words.
