Well, I have fed wellness core, origen, and just about all high end foods. Wellness core was Okbut hard to keep weight on the dogs, taste of the wild was good but you had to feed double amount plus lots of hair loss, orijen a good food but is hard on kidneys, this is because tthey'd drink half thier water bucket daily. Natures Variety instinct grain free duck with freeze dried boost is the best I've ever fed. Super healthy coats, I feed very little of it, they hardly drink any water, and they go nuts over it. The stools are like picking up pieces of Styrofoam. It's as if almost all is digested. Other than the raw that I feed on weekends, I will never under any circumstances feed a different feed. It's that good. My girlfriend noticed a difference after a month and changed her cat food to the cat version.. What a nightmare it's been. The fucking cat is now turning flips all over the house going nuts. Anyway, short answer.. Best kibble out there. My opinion. And this is so eone that keeps a weekly log of weight, water consumption, and how fast the dogs pull me 6 miles on Rollerblades.
