Isabel, Zoë and Rollo are back! But, this time, Isabel’s sweet little puppy is turning into a dog she can’t recognize. So, who’s in the doghouse now?

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?

Caroline Adderson, author of the Jasper John Dooley series, where Isabel was introduced, has created another pitch-perfect early chapter book series starring a hilarious, irrepressible and lovable hero. The short chapters, loads of humor and hijinks and fun illustrations by Kelly Collier on almost every spread are just right for early readers. And the quirky details, well-drawn cast of characters and one-of-a-kind perspective are sure to leave them begging for more the next Izzy adventure. This title is sure to resonate with any child who has ever dealt with an unexpectedly challenging pet. With its focus on social-emotional growth and development, it will spark lively discussions about growing up and taking responsibility.
