Query: not worth it

I bought this toy due to the fact it was rated excellent for tuff chewers by the company. my dog was threw the rope within 30 minutes of giving him the toy. 30 minutes later the shapes of the world landed in his stomach! This is the worst tuff toy I have ever purchased and I will demand a refund from the company. luckily I supervise my dog while playing with his toys or he probably would have eaten the whole thing!
