He totally hated what? A bison bone? I don't blame him. Was the bone bare? Those things are much too hard to eat. Check out my web page in my sig. It will get you started in the right direction.So I figured I would try my dog on a Raw Bison bone, just to see how he does, I switched him to evo, so I was debating raw food. He totally hated it. I tried it frozen, and I tried it thawed out and he wouldn't touch it. Any suggestions?
