Review on Treat Dispensing Dog Toys: Interactive Puzzle Toys for Smart Dogs, Puppy Boredom Relief, Slow Feeder & Digestion Aid (Yellow) by Brandon Mix

We have had this toy for a long time and our Jack Macy loves it! There's nothing worse than a bored dog when you're trying to work. We fill it with pellets and she spends quite a bit of time rolling it around the house and spreading pellets around. When it's empty, she makes us fill it up (although most of the time we don't). It will be hidden until the next day. The toy is strong and holds up well. Not sure how well it would do with a large breed dog but for our 15 pound pup it's perfect. Highly recommended.
