Fantastic that these come in a 3 pack - I wish more chew toys did this! The base for these chew toys is pretty tough! The center & ends are hard enough to withstand both my bully mixes & my Irish wolfhound/Great Dane cross. They’re safe enough for even the largest power chewers! (With Supervision) my American Bully got the rubber spikes chewed off in under 20 minutes which is mildly disappointing but he’s a true powerhouse & master destroyer of all chews so I’m not that bent out of shape about it. I do wish they were as large as they appear in the ad pics but isn’t that the game we all play ordering offline anymore? 🤷🏻‍♀️ • Pro Tip: smear this toy in peanut butter (xylitol free!), wet food mixed into a slurry with water or bone broth + kibble/treats, yogurt, or even pumpkin puree and freeze for a few hours & relax while watching all the organic engagement your dog gets out of this toy!

This bone is indestructible. Finally a toy that doesn't get chewed up to pieces.

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!

Strong

Size: Small, Color: Textured Ring

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.
