I did not gradually introduce raw ingredients to my dogs: I switched cold-turkey (pun intended). The first week I did feed them a mix of ingredients which included cooked rice. The next weekend I took some time reading through the archives of http://pets.groups.yahoo.com/group/rawfeeding and I became convinced that dogs do not need cereal.
The dogs are fed by weight, and I measure each portion with a small kitchen scale. They are getting around 2-3% of their body weight each per day. I feed one large meal in the evening, just as I did before. But now the dogs are more satisfied.
I have quickly become a true believer in feeding carnivores like the meat-eaters they are. The difference in their attitudes about food and meal time is amazing to behold. New coats are coming in shiny, teeth are sparkling white. We have had no incidences of dogs passing bacteria to us through licking or through their waste in spite of annecdotes I had heard or read. And speaking of waste, that has been dramatically reduced in both volume and smell.
I detailed my early progress via blog entries, and will continue with updates from time-to-time.
Update September 2008: 15 months in. I am now feeding almost exclusively chicken for the meat protein, with addition of vegetables and cottage cheese.
