Dr. Duck spends his days and nights driving around in his big red van to help his barnyard patients. He calms Mother Mouse, whose baby has a fever, and listens to the cough of a two-year old beaver. He tells a hoarse cow, "Take two and you'll moo"; for a sheep, cough syrup will do for the flu. But what happens when Dr. Duck becomes ill? With bouncy rhymes and cheery artwork, this tale pays tender tribute to a dedicated country doctor—and his care-giving menagerie of grateful patients.
