Thank you all for good ideas and discussion. I know that some discussion got side tracked, but for me very beneficial.
Just to add few question V had. My dog is 8, years old, she is Shiba Enu, she had one anal gland removed because it had cancer. We feed her Purina One Healthy weight dog food. It was recommended by her Vet. It does have a lot of corn and soy, I bet all GMO.
I found a few good organic meat purveyors in NYC. Also I am increasing Iodine dose to 5 drops and then go to 10.
