    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!

    She sat still and licked peanut butter. I clipped nails!! "FINALLY" 😃😄
    Color: Mixed, Size: Medium, Color: Mixed, Size: Medium
    I have a Belgian Malanois who WILL NOT let me clip her nails. I got this a little bit of peanut butter in the places you can put it under the bottom in little compartments like which she sits and trys to lick it all out of every little cranny and while doing that, BOOM nails clipped and filed. Great product and worked exactly as I needed. Highly suggest if ya need the fur baby to sit still while you brush alor clip whatever you need, it works and if it works for my Dog a Belgian Malanois-look them up-it will def work for yours!!!! Oh yeah another great thing is it's nearly indestructible. I say nearly because she will prove me wrong if I say it is completely indestructible. Good buy. I suggest it for sure.
