Henry wants a dog more than anything in the world?more than a cowboy costume, even more than an all-expenses-paid trip to the moon. So he puts an ad in the newspaper to find the perfect pet. Far away, a lonely duck who desperately wants a friend reads the ad. He has the clever idea to disguise himself as a dog and apply for the job of Henry's best friend. But his cover is quickly blown when he isn't very good at catching balls and his floppy ears and tail fall off. Henry is disappointed for a moment, until he thinks of all the amazing things this duck CAN do, and realizes he's found the perfect pet after all. Fiona Roberton's irresistible illustrations and utterly charming characters will win the hearts of readers of all ages.
