I trust the Nylabone brand and would not buy a cheap substitute to save a few bucks. This ring is heavy duty. I got it for our 9-week-old puppy and it keeps her interested and entertained with all the little nubs. She uses it more as a toy than something to chew on, tossing it around and mouthing it. It's very hard so I'm not worried about her being able to chew off any little pieces at this point. This satisfies her for now and helps to keep her busy and reigns in some of her puppy energy. Recommend!

My French Bulldogs have really strong jaws and are aggressive chewers. These really are sturdy and last a good amount of time. I replace every couple of months and they are one of my dogs favorites and easy for them to hold onto.
