Hole is too large to keep most solid treats contained long enough for this to be much more than a minor delay let alone interactive. I guess it is ok if you plan to use gooey / sticky type things to load within. It holds up ok but my 2 pups have still managed to shred parts off. So I would say durable as they couldn't immediately destroy it like most 'durable' items however it is thin enough to give way and shred. We keep looking for things that will last; we will continue looking.
