The BarknBig Bison Shin Bone ranges in size from 7-10". These BIG bones are delicious treats for aggressive chewers! Our Bison Shin Bones are made from premium-quality, free-range, grass-fed, 100% USA bison. Dogs love to gnaw on the exterior and eat the tasty cooked surfaces on the outside while they work to break down the bone to get to the marrow. BarknBig is proudly produced in Colorado.
