My brother used to have a later edition from the 1980's with red wheels. He loved his wag-along Snoopy and took him out whenever he could pulling him around town, with its wagging springy tail and wobble-along wheels. Many people stopped and made adoring comments - my brother looked super cute followed by this toy pet.
The memory of it always makes me smile and that's why I had to adopt battered old Snoop for €5.
