I agree that most vet's recommend Science Diet becuase they sell it, however our vet did tell us not to bother buying the weight loss from them, but just to buy the Lite from the Pet Store. He said he saw no benefit of one over the over to justify the cost of what they sell.

Basically, my feeling has been that I want to feed my dogs the best I can. But what is best ios going to be different for every dog. Just because a food looks good on paper and has the right ingredients, doesn't mean every dog will thrive on it. And just becuase a dog food has more filler, doesn't mean it is terrible for very dog. I have always felt the right food, is that one that the dog is healthy on...poop and breath that isn't too stinky, healthy coat, and no infections. I guess allI can do is wait and try to talk to the vet tomorrow. Ask them to explain to me what in California Natural they feel causes the infections, why they feel ProPlan is better, and then choose the best food I think fits. Right now, I'm reallying leaning toward going back to Sensible Choice. My mom's dogs do well on it, my sister's dogs have done well on it (they recently switched over from Nutro, which gave them runny poop), and ours did when I fed it to them.

Thanks for all your input.
