One of mine couldn't eat the RC YT...gave them an upset stomach and runny stools.
Mine actually get a mixture of 4 different commerical brands, home cooked food and supplements. But each dog is different and what works for one won't necessarily work for the next.
While dogfoodanalysis.com has alot of useful information, it is based completely on the opinions of the site editors, not long term, professional research. So don't let researching for a good food stop and end there. Another site to try is:
Dog Food Review Ratings
It gives links to various sites that examine commerical foods, raw feeding, home cooking, etc.
