We feed raw to both our Danes. We do our own thing - nothing pre-packaged, no special equipment.
Livia has only been on it for about 6 weeks, but Loki is closer to 2 years
We feed chicken quarters, beef trim, pork/beef heart, lamb and pork as staples. Kidney and liver for organs. Loki gets 3-4 lbs per day; Livia is closer to 2 lbs.
