Dylan, in love with classmate Alice, who lives next door, despairs of ever impressing her after his father, their hated maths teacher, shouts at her to keep her goldador quiet. When Bouncer goes missing, he seizes his chance. Outside Number Twenty-four, home of the mysterious Professor Pringle, he finds Bouncer’s collar. And a talking dog. He persuades a reluctant Alice to enter but gets more than he bargained for when the teens are transported to Dogtopia where human and dog roles are reversed, and Alice becomes Bouncer’s pet. Here he must prove his worth by rescuing his annoying young sister, Caitlin, turned duck by the evil Scissorman. First, however, they must help free Bosona, Top Dog, Pringle’s owner and Bouncer’s new love, but whom can they trust, and where is Ben, Alice’s beloved brother? Shy Dylan’s confidence grows as his bravery is revealed, but how can he ever replace Colin in Alice’s heart?
