Puppy's favourite, but not built to last.
My puppy absolutely adores this tug-of-war ball! However, I have to mention the durability—it started fraying after just a few days of use. While it’s still usable, the material doesn’t hold up well to enthusiastic chewing and tugging. If your pup is a strong chewer, this might not last long. That said, for the price and the joy it brings my puppy, I’d still consider buying it again—just with the expectation that it’s more of a short-term toy. Great for light play, but not built for heavy-duty tug sessions.

Disappointed
This was a Christmas gift for my Shih Tzu. It started unraveling within hours. It's not made well. I'll be returning this product.
