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.

If your pet chews a lot do not buy. My dog chewed the plastic and cut her nose when grabbing the toy because of how sharp it became.

Durable and fun
My puppy, 10 months and 52 pounds is an avid chewer on bones and toys. This has lasted her months and no sign of damage. It’s a keeper!

Lasts Great With a Heavy Chewer
We have had this for two weeks now, and our Pitbull has yet to destroy it. He normally destroys other chews in minutes. Great value, top quality, keeps him well occupied and does not squeak excessively. Seems to have good chewability. Size seems perfect for our 75 lb. Pitty.
