Sort of good for tough chewers??
Color: Deep Roots Carrot - Small, Size: Small Dog
The actual carrot part (orange part) is tough chewer approved and my dog loves. It’s basically the same shape and size as his kong. However the leaves (green part) is not tough chewer approved. He ripped ALL those leaves off and ate them within 5 minutes of me giving him the toy. However they passed through him fine.

Aggressive chewer puppy approved

My aggressive chewer puppy loves this. It is pretty sturdy. He hasn't destroyed it yet and he's had it for over 3 months now.

Pretty hard to clean
Color: Cinamutt Roll - Large, Size: Large
We've had this for about a week now. I have 2 dogs, one small one about 55lb. I bought this for my big girl, but lil man is determined to get the best of this toy. Usually they don't both go after the same toys, so this is interesting.
The trouble is, neither one of them can get all the treats out if something makes it all the way down into the crevice. It's surprisingly deep. The up side is that they'll try for quite a while before giving up. The down side is even if you put it in the top rack of the dishwasher, something stuck deep in there isn't going anywhere until you dig it out yourself.
I tried a plastic knife but it broke the second time I used it in there. I wound up using the metal handle of a reusable straw cleaner. Which then I had to wash that, too. Then it needs to dry overnight before it can be used again.
All in all, the dogs like it fine, it's gross to scrape out and wash, takes longer than most toys to dry, and I have the feeling that will eventually cause me to pass it to someone else's dog long before my two have gotten tired of it. At this point I'm pulling out of the toy rotation for a week or two because I'm not ready to clean it a third time.

Hyena Proof
Color: Acorn - Large, Size: Large
I have an American Bulldog that would chew a brick if he didn’t have an alternative lying around. They won’t last forever (nothing does) but we’ve had two of these over the course of a year and for him that is nothing short of a miracle. And that is daily chewing like it’s his job. I highly recommend the Acornucopia for aggressive chewers with jaws like hyenas…so it’s probably great for your dog too.
