I found this in various places on the internet. I used the livers from 12 fryer-sized rabbits which I guessed to be about 1.5 lbs. I don't know if rabbit liver is milder than beef or what, but they aren't very smelly. I like more of a playdoh consistency; this is more like a biscuit. My dogs aren't good critics - they'll work for kibble and I'm not sure they even taste treats.
