Just wanted to update
I decided to go with Natures Variety Grain Free Limited Ingredient Turkey.
He ate a little bit mixed in with his old food yesterday, I am too chicken to do it cold turkey and today it has more of the new food.
I like that Natures Variety doesn't have potatoes or flax seeds in the formulas. If he doesn't have any reaction to the food then I'll move on to the Lamb or Chicken formula.
Eventually I'll try the raw, it is something I need to research a little more and of course just because because I am so envious of all of you with tiny poopers

HA!
