Great toy!
Color: Grass Green, Size: Medium
We have a boxer and pit mix and he destroys everything. This toy however lasted the longest. He played with this every day and he plays very rough. But after 3 months I finally threw it out. It was still in tact but it was about to start falling apart. I will definitely buy another one.

Great for aggressive chewers
Color: Mixed, Size: Medium
This toy held up well. My dog is a very aggressive chewer and will shred apart any toy she can. She was not able to tear up this one. I have not found many toys that she doesn't destroy

Smaller than pictured
Color: Mixed, Size: Medium, Color: Mixed, Size: Medium
It’s a lot smaller than pictured and I have the same dog type as was depicted in the one of the pictures. The dog like it so I guess that’s good. I will not be playing tug of war with him using this. I like my fingers thank you very much. I would say it durable. He destroys most toys in minutes. He did destroy the squeaky part in about 10 minutes so bonus points for that.

Not for aggressive chewers. But still a good product.
Color: Mixed, Size: Medium
Cute toy, my dog was obsessed with it, but within like 1-3 days I couldn’t put any treats in the places for it as my aggressive chewer dog destroyed it within a day or so haha. But she still loves it and just chews on it for fun. Doesn’t last long with aggressive chewers if you’re looking to put treats and such in it like I did. But again that part may be broken and she still chews on it so not too bad!
