Great for larger dogs
Color: Grilled color
I think they were heavy duty and durable, but they were too heavy for my dog. The seller was excellent though!

It ok but a bit small for my golden and I have to supervise him.
Color: Grilled color
I don't recommend. Too big for my small dog. Too small for my big dog. They have similar bones but these just seem odd. ** WELL actually after some time they both will chew on them, especially my golden. Do be careful watch the dog while chewing. My home health care aid thought they were real. they are holding up well.

Finally a chew toy my aggressive chewer can’t destroy
Color: Grilled color
I’ve gone through countless “indestructible” dog toys that lasted maybe a day—sometimes only minutes. My dog is an aggressive chewer and treats most toys like a personal challenge. These Fuufome chew toys are the real deal.
Right out of the box, you can tell they’re made from tough, high-quality nylon. My dog went to work on them immediately, and days later there’s barely any noticeable wear. No chunks missing, no sharp edges, and no mess on the floor. That alone puts these way above most toys I’ve tried.
I also love that they actually keep my dog busy. Instead of getting bored and looking for something else to chew (like furniture), she’ll settle in and happily gnaw on these for a long time. It’s been great for mental stimulation and for redirecting destructive chewing.
The fact that you get two durable toys in the pack is a bonus, and they’ve held up exactly as advertised. If you have a large breed or an aggressive chewer and you’re tired of wasting money on toys that don’t last, these are absolutely worth it.
Highly recommend—this is one of the few chew toys that has truly lived up to the “indestructible” claim. 🐶💪
