Description:

When a new dog obedience business opens in Greenfield, the Aldens decide to enroll Watch for a refresher course. At the first class a Dalmatian goes missing, and everyone wonders if the dog ran away or was stolen. But when a malamute disappears at the second class, Henry, Jessie, Violet, and Benny know they have a mystery on their hands. Could the thief be the class's instructor, the Dalmatian's owner, the dog groomer, or the owner with the very obedient dog?

Three children and an uncoordinated dog track down the mastermind behind a rash of household robberies.
