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. In the end, the family is left without food so the families of the other dogs share their meals; and they all end up celebrating together. Contains an informative section on the Fourth of July.
