As far as a treat dispensing toy, this is a great product. My dog loves it. However he loved it so much he has chewed through it. The product was advertised for aggressive chewers but my Spoodle managed to chew through the handles within a few days. I would only use to to dispense treats when leaving your dog alone for short periods then I would remove it.
