Bones are only safe to feed when RAW. Raw bones are soft and pliable. Bones that have been heat treated in any way – e.g. boiled, baked, fried or braai’d – become brittle and are likely to cause splintering and choking. If undigested, they can pierce or clog the intestine.
We highly recommend giving your dogs and cats RAW meaty bones as part of their RAW diet. (You can even feed raw fish bones, provided you pop it in the food processor first.)
