Great buy!
My large dog has been chewing on it for months. She loves it and it’s almost indestructible!

A challenging chew.
We have 3 Gordon Setters, 2 of which like toys to chew on. These last a long time. The only thing I would caution ⚠️ you about is that over time, these develop sharp edges. If they rub the toy on you, you will know it. Especially if you are wearing shorts. I do like these toys for their longevity.

My god loves his new chew bone 😍
My dog loves this chew bone, he chewed on it daily since I gave it to him. It's good value for money, pretty hard, lasted about a month & a half. Good size bone for a medium sized dog

Long lasting bone for aggressive chewers!
My dog loves to chew on this bone. She is a corgi, very aggressive chewer. This bone will last forever.
