My dogs can’t get enough of this very noisy ball. We have one outside and one in their playroom. It is very noisy. It is very hard. So, I’d say a room with fine furniture is not the place for it. Ours bang it around pretty good. Our boxer did split one, biting it. But, she’s a serious chewer! Our other dog carries it around sometimes but hasn’t been able to damage it yet. So, I’d say for most chewers it’s going to last a long time. It’s a great toy but in most households I’d say basement or outside. Again, it’s hard and did ding a few baseboards.
