Book excerpt: Isabel and Rollo are back … but, who’s in the doghouse now? Isabel’s dog, Rollo — “the cutest, funniest puppy” — just doesn’t seem like himself lately. Besides not fitting into her best friend Zoë’s doll clothes anymore, he’s become much harder to handle. Like when he pulls away from both girls to chase a squirrel — then keeps running! Or when 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? Has Isabel created a monster?! Kids won’t be able to look away!
