It looks just like this and I believe it's the Medium size.
There is one problem with it though... Gimli lost it.
A number of months ago, I gave it to Gimli with some carrots in it, while I gave Merida a different treat dispenser. The last I saw of it, he was laying on his side pawing at it in the spare bedroom. When I went to add more treats, I couldn't find it.
We've turned the house upside down, but we cannot find it.
Gimli's not talking, so we're at a loss. I'm sure the next owner of our house will find it one day and wonder what the hell this old, crusty, hair covered thing is.
