The web is very disceptive on this as their web sites both claim to have 4 stars and voted 2nd best by DogAdvisory. Bummer,
All those Food Advisory web sites are bull shit. Sorry. They rate ingredients only, not the formula. I would rather have happy healthy beautiful dogs on my 3 star Pro Plan, than dogs with bad coats and diarrhea but gosh darn it, they are eating a 5 star food.
Yes, Yes, Yes! Ask my litter of puppies that had unremitting diarrhea for 3 weeks on Wellness. We ruled out worms, coccidia, giardia. . . everything that could cause this. Finally, I thought, I'm going back to my tried and true ProPlan Puppy even though it's supposed to be a crap dog food. Two days later. .. perfect poopies.
I tried Diamond Dog Foods, in a couple of different varieties, for my adults over the years, because the ingredients look so wonderful. Each time, the stool situation was out of control for a long enough time, that I realized it was the food and not the adjustment time.
My dogs have been on Nature's Domain, Salmon kibble for the past 3.5 yrs. I did try the ND Turkey, one bag but it gave my dogs loose stools so I switched them back to the Salmon. Best dog food I've tried all these years, $33.00 per bag !!!!
