Question
How safe is it to feed a Golden Retriever pork rib bones?

Answer
Please don't.  They start out with sharp ends and small enough to gulp down and choke.  A full grown Golden could also easily crush them into sharp shards.  Your golden will do just fine without any real bones at all.  Same with rawhide and other such products.  Stick to safe stuff such as Nylabones and Kongs.
