I'd previously had a Dr. Noys medium-size teddy bear to play tug-o-war with my 30 lb knee-high sheltie, and after 6 months of tug-o-war, it looked like it had open-heart surgery.  Held up quite well (looked perfect for the first 5 months), so I decided to get another Dr. Noys toy for my little girl, as she loves stuffed toys.
