This is the story of a boy named Barry. Some stuff happens, and overnight like magic he turns into a boyhound. Not a hound, but a boyhound—which means while he may still look like a boy, he is, in fact, a dog. And even in his boyhound brain, Barry knows there are lots of advantages to being a dog. You don't have to clean your room or use dental floss, for example.
But things get crazy. He eats something too disgusting to mention. He's attacked by telepathic squirrels. An innocent squashed frog gets involved. Plus, his mother's pretty mad. And that's all before the really bad thing happens. . . .
