Just to clear things up a little. There is a big difference in the quality of Pro Plan versus Hi Pro. This is my opinion but the quantity of stool between Pro Plan and Hi Pro is fairly substantial. I feed my Draht and Britt Pro Plan performance 5 months out of the year. I use the Pro Plan Adult lamb and rice formula the remainder. I have tried Diamond Performance in the past but my dogs had terrible gas even after a month with adequate transition into the dog food. There are plenty of folks out there that use Diamond it just dosen't work for me. A friend of mine uses Hi Pro with his Draht and is happy with it. I know he spends a lot more time behind the pooper scooper than I do with my two dogs. If you want to save money I suggest using Purina ONE. This is what I used up until 20 months ago when I switched to Pro Plan. A little more stool but a good food. My dogs seem to control their weight a little better with Pro Plan but I am probably more worried than I need to be.
