It’s empty in here!
I found it a really good toy except for the noise which I hadn't realized it made (I'm sure the dog loves it). How annoying that mine didn't break whereas other customers who wanted it said it did.
My 15 month Akita loved it but it's not strong enough and the squeak stopped working after about 3 days. He still played with it and then chewed most of the handle for the next a couple of days:(.
