Following up a few years later. At this point, I just dig a hole in the garden and bury the bones and guts. Animal remains currently buried include bears, elk, cows, bison, rabbit, and chicken. I usually add about a foot of wood chips on top to soak up the smell and that slows down the dog. I have learned that I can't let the dog watch me digging or he will come back later and re-excavate. We do burn some bones in the wood stove and the add the burned bones to the compost pile.
