lol.. well from my experience Natures variety has changed my pup for the better.. his Poo is better.. doesnt eat it anymore..His coat is BEAUTIFUL and healthy and shiny and he eats everything i put in the bowl. I used tohave to mix his old food with treats so that he would have something in his belly.. but now i just put it down and BAM its gone.. he licks his chops and he is happy

I have him on the rotation diet.. kibble,can and raw.. the pet shop that i went to gave me some samples first before i bought the whole thing.. but i was back the next day buying it up..
he is 5monts and 2 weeks and no tummy problems which wasnice.. the raw food did make it a bit runny but still solid.
and he only poops 2 times a day b4 it was 4 and potty training was harder now i know he has to go #2 inthe morning and wheni get home from work...
So my 2 cents is Natures variety was the choice for me.. im happy and hes happy..good luck in your search!
