Ralston Purina Chuck Wagon 1975 dog rubber squeak toy.  It measures about 8 inches long and about 4 inches high.  It is missing some paint.  The wagon is somewhat dented in on the sides.  Marked "Ralston Purina Company c 1975" on the bottom.  This advertising character toy is modeled after the popular Chuck Wagon "Wagon Chase" commercial  that had a little wagon riding past the dog.
