Which food is better? Blue Wilderness or the regular Blue Buffalo dry foods?

I am currently feeding Blue Buffalo to my 2 dogs. I was picking up some canned foods for my underweight Shih Tzu (as instructed by the veterinarian) - and I noticed something called "Blue Wilderness". The bag was metallic navy blue with a wolf on the front.



I read the ingredients and I didn't see anything wrong.



What is the difference?

Blue Wilderness is grain free all natural food, and IMHO a better quality food. Blue buffalo is a good quality food with grain in it, but blue wilderness is their top of the line food.
