I've pasted the ingredients for Iams Chunks below. It reads like a nightmare. The first ingredient is chicken, raw chicken. It's heaviest by weight before they cook it but then it's, in reality, the 6th or 7th ingredient by weight after it looses all the water. So, you are feeding a corn based food. You have 2 grain sources as your main protein before you get to the chicken BY-PRODUCT meal. That means all the crap that isn't meat is added to the food. So, now you have no meat based protein in the first 6 ingredients. Add to that the NATURAL chicken flavor, I shudder to think what THAT could be. Beet pulp for nice dry, hard stools, followed by 27 additives. Notice the DL-Methionine.....they NEED that in there to keep your dogs ph low enough to prevent struvite crystals, or try to anyway.
It's a crap food that will cost you a hell of a lot more in the long run than forking out a few more bucks for higher quality foods.
