Whats your opinion on Innova Evo dog food

[bklevar]

I was just wondering what you thought about the Innova Evo dog food. This food is 42 percent protein and 22 percent fat with no grains. I read on another forum that dogs on this diet can become chronically ill. Is that true and why would it be. Sounds like an excellent food to me. I am wondering about feeding it to an older less active Shih Ttzu. I'd like your feedback if you know anything about it. Thanks
