When a little dog appears at a family picnic, the girl and boy play with him all afternoon, and they name him Willy. At day's end they say good-bye. But the dog has won their hearts and stays on their minds. The following Saturday the family returns to the picnic grounds to look for Willy, but they are not alone -- the dogcatcher is looking for him, too . . . Caldecott Medalist Marc Simont's heartwarming tale of a stray dog who finds a home is told with appealing simplicity and grace.
