So Taste of the Wild is manufactured by Diamond and is on Whole Dog Journals approved list of food. They only listed the Wild Sierra Mountain as an example which contained 25% protein 12% fat and is lamb based food.

So I did not get very far with WDJ for you Most of the sample foods listed for each manufacturer averaged about 24% protein and 12% fat, even the Blue Buffalo Basic Turkey and Potato was 22% protein and 12% fat. I'm not sure how low in fat you need to go.

But what is crazy to me is the Canidae Salmon and potato has 40% protein and 20% fat
