I have used Purina products over the years. I used dog chow for years, but always had lots of shedding, to much poop and hot spots. Over the last 3 years I had used natura products, wellness, eagle pack, canidae, natures variety and others of the top healthy dog foods with mixed results but some were always the same. I always had stool eating and dogs who were always hungry. If I tried to feed more the result was very loose stools. I have used Pro Plan and Pro Plan Selects for awhile now and my dogs have nice shiney coats, very small stools and they are not hungry all the time. So even though alot of people say this food is crap, I say go with what works for your dog and for me Pro Plan works. This review is for the original Pro Plan and the Pro Plan Selects, not the new stuff with the shreds.

Update: Had to change back to Diamond Naturals, my Yorkies were getting hot spots and scratching all the time. My Boston was doing great on the pro plan, but changed her also.
