No idea. Fine for very small dogs wouldn't recommend for larger dogs. My dog bit the face off within a couple of weeks and he was a puppy then. it was subsequently binned to stop the (presumably barley or wheat) filling coming out all over the place.

I do not feel that I can comment on this because the item was not sewn correctly and the filling was visible, dangerous for a puppy. I tried to mend it but have to observe my puppie's play with it. It has not been washed yet as it has hardly been used.

My new puppy loves his. Warmed in microwave before bed time and he rests his head on it. During the day he loves the noise the wheat inside makes. Worth the purchase.
