Alright so the eyes and tounge are the first things to come off. They eventually get the elastic out and, i tie it off, many time. I seriously have 5. Way better then giving my dog a rope and having that tied up in his digestive system. The ones i have are all in smaller pieces now and i order more once in a year or so. Anyway. BUY THEM, they are awesome and my dogs love them. They arent made of rubber, but what that you can play tug a war with your dog would be rubber.
