In Barksdale Academy (in the town of Barksdale) most canines strive to be Best in Show; Nova, Duke, Harley, and Peanut have never won anything, but this year Nova is determined to get her pack to pass their agility exam--even though Duke is afraid of the high ramp, Harley just wants to chase squirrels, Peanut can not make it through the hoops, and Nova herself gets so excited she keeps knocking the whole practice course over.
