Our Rosie has also chewed through almost every “tough chewer” toy on the market. However we found a ball called The Almost Indestructible Dog Ball that she loves to play with. She has a big one for outside and a smaller one for inside. She’s had both for over 6 months and, although they have chew marks all over them, they are a very hard plastic so they can’t pop. They aren’t chew toys though…she chases them around and plays nose soccer with them. For chew toys, we get her the Nylabone Big Chews. Sorry, I’ve got no idea how to keep him contained. Concrete bunker in the basement maybe (just kidding!).
