The Hundred-mile-an-hour Dog

Streaker is a mixed-up kind of dog . . .with quite a bit of Ferrari and a large chunk of whirlwind . . .Streaker is no ordinary dog. She's a rocket on four legs with a woof attached, and Trevor has got until the end of the holidays to train her. If he fails, he'll lose his bet with horrible Charlie Smugg, and something very, very yucky involving frogspawn will happen . . .
