We got our dog two nylabones and this benebone and he really prefers this one. Like the nylabones he barely even looked at, but he loves this one so much it's starting to splinter off a little. Apparently it can just be sanded down again but I'll probably end up getting more of these so that we can switch them out. I noticed that the shape also helps him be able to handle it with his paws.

Initially showed little interest, then decided she loved it

The product itself looks great and is clearly very well made but my dog had zero interest initially in this which I find odd because many other similar toys she has attacked. Update —- several weeks later all of a sudden my dog decided she liked this and started chewing on it and has been her favorite - go figure Update 2 — it’s become her favorite chew and she’s obsessed with it! My older dog started chewing on it, and it broke one of her old teeth!
