I also had a small Yorkie which I made his food. This is what I did, in a rice cooker I put a cup of brown rice, a carton of chicken livers, some chopped garlic, grated carrot and flax seed oil. About a cup and a half of water and a chicken boulion. Turn on the cooker and let cook.
I then let it cool and cut the chicken livers down smaller. If you think your dog would like peas or some other veggie better, use it. You can use canned chicken stock instead of the water and boulion cube. I told a vet once I was doing this and he thought it was the best recipe ever that everything in it was superior good for the dog. Since the food is soft, you will have to pay special attention to his teeth, Yorkies are notorious for bad teeth.

I use brown rice, chicken livers, carrots and add garlic and flaxseed oil for my dogs. The vet said it was a great food for them. I always was concerned that maybe the chicken livers might be too much. Anyone know? I like the pressure cooker idea. I had been putting the whole thing in my rice cooker another words, cooking everything together.

do you use dill or sweet pickles?
