Love it, nice for tough chewers, split in half during play
Size: X-Large, Color: Textured Ring, Size: X-Large, Color: Textured Ring
LOVE THIS PRODUCT, would’ve gotten 5 stars but i threw it for my dog and it split in half on contact with the floor. It had lasted us well over 5 months, it’s not his favorite toy but he’ll pick it sometimes, i wouldn’t say it’s unsafe in half just don’t give the smaller parts!

Great for power chewers
Size: Large, Color: Bundle
Nothing beats Nylabone!!! Our lab has destroyed everything else… even the extra durable black kongs. Finally a chew toy that is super durable and great size.

Heavy duty, excellent quality
Size: Small, Color: Textured Ring, Size: Small, Color: Textured Ring
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!
