Food is a hot topic on this forum.
All I can recommend is to not stress over it because all the advice and commercial kibble can make your head spin.
FYI, dog food ingredients have to be listed in order by weight, so the heaviest ingredient is the first one, so on and so on.
Based off the ingredient list you posted, chicken is the heaviest the ingredient. However, I really doubt it is what actually makes up the majority of the food.
Notice how many different forms of rice are listed in only the first 6 ingredients: brown rice, rice flour, rice bran... this is a prime example of ingredient splitting.
When rice is broken down, it can be divided into many forms (bran, flour, etc) and of course will weigh less individually. If you add all those rice products together, rice would most likely be the main ingredient of that food, not chicken.
Not saying it is bad food or good food, because I've never researched it, but just wanted to give you a little heads up at how the ingredients can be deceiving.
I believe based on the research I have done and the ingredients listed above + how my puppy and dog respond to the food that I have made a fairly educated decisions on what to feed them. For the most part I am aware of how the ingredients work. There is still NO mention of the evil words, "corn gluten meal," in the Nutro brand.
. Some of the other foods recommended have caused problems, so I'll stick with what I feed
. I find here on this forum the people who are not for kibble, or list most of the cons, feed raw and I never will...
