They get some raw once in a while when I cut up a whole tenderloin or a whole strip loin when I buy them from costco. Once I've cut up the steaks I usually give the guys the pieces that are too small to do anything useful with and they love them. Today I got a huge pack of stew beef at costco and gave them each a bowl of the chunks for their dinner tonight. They wiped it out in no time.
Both are now sleeping their dinner off. I may have to try them with some raw chicken one of these days too.
