Would not recommend
I bought this for my bulldog/boxer dog thinking that it was completely made of leather but it’s not. It has an inch of felt type material between two very thin leather pieces which makes it easy for her to chew on, becoming soft very quickly and then falls apart. We took it away from the dog the first day and threw it away because we didn’t want her swallowing felt type material.

Tough chew approved!
Finally a toy my french bulldog cant break! We have a 9 yr old man who loves to chew leather belts and purse straps. Found this leather toy, he got it today for Christmas and he loves it!

The bone lasted a long time.
My border collie is a chewer. I can look at a toy and tell you how long it’s going to last. This bone has lasted months and she still will grab it and chew on it.

⭐️⭐️⭐️⭐️⭐️ 5/5 – Finally, a Dog Toy That Actually Lasts!
We picked up this natural leather bone dog toy hoping it would survive longer than the usual toys our dog destroys in a day—and wow, it exceeded every expectation. The leather is thick, durable, and clearly great quality. Our dog has tried his best to tear it apart (like he does with every toy), but this one has held strong.
It’s been weeks now, and the toy still looks almost new. No frayed seams, no stuffing everywhere, no pieces breaking off. Just a solid, long-lasting toy that keeps our dog entertained without us having to constantly replace it.
If you’re tired of wasting money on toys that only last a few hours, this natural leather bone is absolutely worth it. Tough, safe, and built to last—our dog loves it, and so do we!

Great chew toys
Dogs love! Not rough on teeth. They do tend to pull long strings of thread off the leather and felt, which must be intercepted and cut off lest we have a string linear foreign body. I wish the whole held together a bit better. Fierce corgis can go through these pretty quickly.
