The Underdogs and their classmates are taking a break from competing in the K-9 exams to go on a camping trip! The fourth years at Barksdale Academy are heading to Camp Ruffing It for a few days of hiking, swimming, and roasting marshmallows by an open fire. Or, that was the plan. But Harley keeps getting distracted by all the sounds and smells in the forest. Every time she runs after a chipmunk or a shiny fish, she accidentally messes things up for her friends. Can Harley stay focused long enough to save the rest of the camping trip? Or is it back to civilization for the Underdogs?
