One of my dogs, Orion, has always been more interested in bones than his sister Bear. I gave them each one of the ostrich bones, and Bear zipped through the wing bone, and Orion put a big dent in the cane. Then Bear stole the cane, and I opened up the big hip bone and gave that to Orion. She stole that too. I finally separated them and the both chewed on whatever was left for over an hour. They're both SOUND asleep now, and seems like both the cane and the hip bone have enough life left in them ...
