Yappy Dog is part of the Kooky Zoo series.
The same mold that was used for Yappy Dog was used for the Cow B dispenser.
Original PEZ creation
Yappy Dog comes in varying shades of orange and green. Beware of a blue version floating around. This is NOT a legitimate dispenser and is nothing more than a blue Cow B head with its original parts removed and replaced by Yappy Dog parts. There will be glue residue around where the Cow B parts were removed.
