Not Safe – Choking Hazard Concern
Color: Multi color
I purchased this toy based on its promise of durability and safety, but unfortunately, my experience was alarming. Despite being marketed as “indestructible” and safe for aggressive chewers, the toy quickly showed signs of wear and began breaking into small, sharp pieces. My dog almost choked on a fragment that broke off during a normal chewing session. The “food-grade nylon” claim feels misleading when the toy fails to hold up under pressure. No matter how authentic the scent or how entertaining it might seem, a chew toy that poses a choking risk is simply not safe—especially for strong chewers. I had to throw it out within hours of opening the package. Please reconsider your dog’s safety before purchasing. This toy is not worth the risk. Manufacturers should be held accountable when safety claims don’t match the actual performance of the product.

Great toy
Color: Multi color
My dog is a chewer and has torn apart many toys. These are great, they are tough, not soft, and don't get destroyed easily. I recommend these for dogs that easily destroy indestructible toys.

Very indestructible
Color: Multi color
I have FINALLY found a dog toy that is indestructible! The other chew toys for aggressive chewers do not hold a candle to these chew toys. I will be buying again and again!!
