Not durable at all!
Size: Small
I have a 25 lb terrier that tore this into six pieces in about 8 minutes. They're big ones are durable but this one is horrible. Do not get this if your dog likes to chew on things.

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!
