Top shelf lines. These products, including Science Diet and Iams, feature higher-quality ingredients but still have artificial preservatives and other chemical additives. I place some "natural" products in this category because they are made with inferior ingredients such as "wheat flour" (a euphemism for white flour). If the product is made with whole grain, it will say "ground whole wheat" or "whole-wheat flour." There are, unfortunately a number of low-quality products that come with high-sounding names.[/QUOTE]
 
Brooke, thank you for sharing all of this informative information. Very impressive. I have been using Royal Canin for about 2 years now and am becoming rather suspicious that the high fat count is causing some repeated digestive problems that I am having here with 3 of my babies.
I would like to try switching foods but not sure which to switch too. 
May I  ask what food you are feeding your little guy ? I do not like all of these chemical preservatives either. In the days before all of these many brands of dog food there was basically on Purina for dry foods. I cookeda fresh beef hamburgerfor my Yorkie every single day for the 17 1/2 years that he was with usand he never had a single illness until the very end when he passed away. My dogs here are all young, the oldest is 6 years and they always seem to be having one problem or another. Diareaha, throwing up, and then HGE. Vet recommends switching to Purina One, but I am not sure Iwant to do that. Thanks again
