I was wanting some opinions on these three foods. I plan on switching to one of them. Thanks in Advance...

I'm assuming this is for an adult dog, and no special requirements?

I didn't vote, because all of them are good foods. I've fed Innova and I've fed Diamond products (who makes Kirkland) and am satisfied with both. I don't like Natural Balance because of its low protein levels, but that's strictly for my dog. It's not a bad food, it's just not a good food for Jes.

Is there a reason you chose these 3. Are these the one available to you easiest? I am unsure of natural balance. I am not a huge fan of Diamond. I know Innova is good, but is too expensive(at least where I live) for me. But if I had to choose from these 3 I would say Innova.

Dakota has been on both Diamond Naturals and Innova. She did wonderful on both brands. What I liked most about Diamond was that Dakota grew at a slow/even rate.. What I liked about Innova was that Dakota only went #2 twice a day vs the 3 times a day she did when she was on Diamond.. lol.. I never notice a difference with her coat when I switched her to Innova. She's never had ear or skin problems, hardly sheds, and she never has the stinky doggie smell.. I guess it's because she eats good food.. :)

Very happy with Kirkland C&R here. Never tried NB; Zoe didn't do well on Innova.
