If you read this article on Suebee's diet, she uses Solid Gold Holistique Blendz dog food as the staple diet. She uses the grain mix (ingredients listed on site) along with the dog food.

I don't recommend using dog food that is low quality as food for your rats. If you use something like the dog food (with comparible ingredients) Suebee uses, then I think it would be fine.. But you have to feed a high quality grain mix along with it.

When I had rats, this is what they were on.. I used the Solid gold and the grain mix as well.. All of my rats were very healthy.
