Here's Middle School for young readers through the eyes of Rafe Khatchadorian's misbehaving mutt, Junior! When rule-breaking Rafe has to train his new dog in obedience school, things are about to get really ruff!

Junior's family goes on vacation without him and he gets into mischief at the kennel.

Excitedly accompanying his human family on a camping vacation in the woods, canine Junior happily chases raccoons, fetches sticks and doggy-paddles in the lake, before an obedience-obsessed human arrives and spoils his fun.
