Durable dog toy
These tall tails natural dog leather toys are great for my dogs. And even the stronger dogs who come to visit can't destroy them as fast as the other toys. The pups all have their favorite whether it is the log, the fox, or the bone.

Great item
I have several of these for my German Shepherd and Hound dog. While the Shepherd can still manage to get this apart it takes a lot longer than other chew toys.

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.

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.
