It is the 4th of July, and a family prepares to go for a picnic. Champ, the family dog—who does not want to miss the celebration—secretly hides inside the food basket. When they arrive at the park, Champ has a feast of his own with other dogs that have arrived with other families. The family is left without food, so the other families share their meals; and they all end up celebrating together. Contains an informative section on the Fourth of July.
