Great dog bones! These are a nice size for my 55-pound Aussie, as well as our 96-pound Alaskan Shepherd. They are big enough to last for a while, and big enough to see so that I don't step on them with my bare feet; part of this is that they stick up off the floor a bit, instead of being a flat bone, all in one plane.

Nice size, the quality is changing. It is softer I believe than it used to be.

Not sure if something has changed in the way this product "Barkbone" is made. I bought this many times before and it lasted. Today, on my dogs first day of use, he had chipped through the material, and already destroying it. he has had it for less than 3 hours.

Great long lasting chew

Flavor Name: Peanut Butter, Size: Large, Flavor Name: Peanut Butter, Size: Large

We really like having these bones on hand to keep our power chewing pitties busy. The large sizes are super convenient and long lasting, and our dogs really seem to enjoy them. We have gone through several orders over the last few years, and I anticipate to keep buying this brand.
