Dobby (Doberman) and us love the bumi products. We had problems finding a toy that he couldn't destroy in short order. Some of the bumi toys are over a month old with countless hours of rough play time and they don't show any wear, they look like the day we bought them. We have recommended these to our Vet, Dog Boarder, and Friends. Two specific toys he loves are the Hurley and the ZOGOflex.
