The second book in #1 New York Times-bestselling-author Katherine Applegate's fun new series.

Doggo likes routine: napping, eating, and more napping. Life is good.

Life is good for Pupper, too, even though he worries a lot, about things like giant squirrels. If he were braver, he might even be a hero. Maybe even a hero who can fly! But heroes aren't afraid of giant squirrels . . .

When Doggo and Pupper meet a baby bird who also has worries, they are determined to help. Doggo and Pupper may not know how to fly, but they are very good helpers. Maybe they are even heroes!

Doggo and Pupper Save the World continues the joyful new series by beloved author Katherine Applegate, with illustrations by Charlie Alder.
