My dog and I both love this. and we'll definitely get another. She has gotten this filled with treats nearly every day since we have gotten it. It gives her a solid challenge and she looks forward to it everyday, I do as well as it keeps her busy for a WHILE which is nice!

There is only one con, and this is that there are treats that are stuck in here that she wasn't able to get out and I haven't been able to get them out myself. Making the x another couple of millimeters larger or even letting this size be a medium and making a large would be absolutely awesome!
