I found the ingredient list I had clipped out of the 'Wellness' brand I originally fed my dog. First 4 ingrediants:
Deboned chicken, salmon meal, fish meal, oatmeal.
It's a very good premium brand (I jump after anything that includes fish in it), but I'm still looking for a reasonably cheap source. What I feed my dog now isn't quite as nice (still a decent quality though, Kirklands from Costco) but it's atleast 1/3 the price.
