The Rub-a-dub Doggy was a plastic toy dog with soft ears. It was made for the bath and its head moved from side to side. Rub-A-Dub Doggy came out in different colours such as including pink, purple, black, light blue and white. They also came with a soft bone-shaped sponge.
I remember that my Rub-A-Dub Doggy lived in my bathroom for many years!
