taste testing... doggie style

i am sort of embarrassed that i actually did this... but it was a suggestion from a professional! i am switching scooter's dog food to an all natural grain free diet and i was given 4 different samples from 2 different brands. so, i set up a taste test. i can't prove there is any science to why, but he did choose one over the others!... until he moved on and ate another, and then another. but oh well, the ranking system worked and we have a winner. core wellness original canine formula. i'm sure everyone was dying to know this piece of information.
