Great for my Cane Corso - a Power Chewer!
These are great for my large Cane Corso. He is 130+ lbs and loves to chew bones of any kind. These last a couple months for him and keep him occupied.

DO NOT BUY- HAZARD TO ANY PUP
This is the worse chew toy I’ve ever purchased. Should’ve had read more than the first couple of reviews and I wouldn’t have wasted my money.
My 18 month old Lab chewed it up in just a couple of hours..she swallowed some pieces and a lot of pieces were left all over my floor.
Took it away from her and threw it out immediately..definitely NOT good for chewing, please don’t waste your money.
Wish I could’ve give. 0 stars but you have to place at least 1 to leave a review 😡

Not bad
I think my dog has special chewing Powers because he pretty much started chipping away at that bone on the first day with particles of the bone fragmenting so I had to take it away because I wasn't sure if he ingested any of that. It's definitely chewable. But I think he's next level. But for a regular tour or mild chewe I think this would be perfect

TOO REAL
Sometimes I can't tell if this is a real stick or a fake stick. I think my dog can tell, but I cannot. But what really defines a stick? It's length, it's shape, it's wood? Are any of us a real stick? I hope this review brings some comfort to the lost and lonely.

Chew stick
Bone is heavy and smells good. For heavy chewers like my pups, it lasts 3 weeks but, she loves it.
