I'm doing raw with Harper but using beef. It comes frozen in rolls like hamburger meat. Once I thaw one out, I was told to use it within 3 days (and throw away what I don't use) and never refreeze it. I also mix in chopped veggies with his food. My 14 year old dog started eating the raw meat too - they both love it, and just sit patiently while I fix their bowls in the evening.
