I had my little guy try out Duck/Potato and Spotato/Venison and he barely ate any of it. Whatever he did eat caused weird poops, like little pebbles, not tootsie rolls
. He would always eat some and spit some out and eat enough just to get by....on EVO he eats like a COW. I also always felt it did not have enough meat in it since meat is not the 1st ingredient item on their list. I am no expert though by any means...
