Its all very confusing,- feeding raw.
When i can my dogs get complete rabbit, or half a chicken, or any game bird. I have decided to try and go onto only feeding the BARF. I have just ordered the book Work Wonders, which states that meaty bones are the main part of any dogs feed, and that a dog would be perfectly healthy if only fed half a chicken , as the meat and bones provide all that is needed. Then once every two weeks a meal of liver only.
I was going to feed kidney in the morning for vitamins, then the chicken, rabbit etc later for the main meal, but reading what you are all writing
