"Isabel's dog, Rollo--'the cutest, funniest puppy' ever--just doesn't seem like himself these days. For starters, he doesn't fit into any of her best friend Zoë's doll clothes anymore when they try to play baby with him. But worse, he keeps doing things that get him into a very big amount of trouble. Like, even when both girls are holding his leash, he manages to jerk loose to chase a squirrel--then keeps running! And when no one's looking, he eats everyone's ice cream, right off the table! Sure, Isabel bent the rules (or, um, had no rules?) for Rollo when he was a baby. But now he's a teenager--and he's out of control!! Is there a cure for this?"--From the publisher's web site.
