It started out that we got them each a bone.
Now since Topeka has passed, Cairo and Phoenix had not really established who was the alpha dog, when Topeka was alive there really was never any question - she was Queen and everyone new it. She could make Cairo lay on his back in submission if she thought he was getting too wild, and with just a look Phoenix would get out of her way.
So after much debate and discussion - Cairo won as the one in charge. And although they each had their own bones, they would wrestle and tease each other with one and totally ignore the second bone. Because you know, what someone else has is ALWAYS better!
