Fenway has two jobs. He must love and care for his best friend and favorite short human, Hattie. And he must protect his human family, especially from the thieving chipmunks. The chipmunks strut around like they own the place but Fenway will not have it. He begins a daring chase to get rid of the pesky chipmunks, which lands him in a bush filled with bees. Poor, heroic Fenway suffers a paw injury but even worse, his humans will not let him lick the pain away! Instead, they take him to the Place of Fear and then Hattie doesn't even help him take off the Cone of Doom!

Fenway never would have expected Hattie to do these things to him. Doesn't she love him anymore? But even though his family is acting weird, Fenway is determined do whatever it takes to make them all happy again.
