My dog and I have thoroughly enjoyed this toy so far. It keeps her entertained for a good amount of time and provides her not only good physical stimulation but mental as well. Often times with toys that you can hide a treat it, it seems my dog is able to get them out too easily. Since this is larger, she's not able to fit her mouth around it enough to be able to crunch up whatever is hidden inside to get it to fall out. So far I've put in baby carrots, mini milkbones, and even some of her kibble. It's also a great toy to play fetch with and she'll often bring it to me in the backyard to pay. Seems well made and durable, despite all her chewing to get at the treatos inside, she hasn't ripped any of the rubber yet.
