Mumbies is a Franklin, Wisconsin dog brand built around natural chews. Its Original and Root Chews are 100% coffee tree wood, which resists cracking and splintering and softens into fibers as dogs chew instead of breaking into sharp pieces. The line also includes coconut rope toys for tug and fetch, and Yummies Bison Liver treats for simple rewards. Mumbies began with one rescue dog, and rescues are still at the heart of the brand.
