Kangaroo leg bones are a popular long lasting bone treat. Our Bones of course, like all our treats are not cooked – they are dehydrated at low temperatures to ensure they do not calcify. Its the calcification of bones which occurs during cooking at higher temperatures that cause bone to become brittle and shard into sharp nuggets increasing the risk of causing internal damage or chocking. We have never had a reported injury with our kangaroo Leg Bones and we have sold 10’000 of thousands of them.
