I sent my husband to the feed store and specifically requested Mrs. Pasture's Horse Cookies. The store was out of them so my husband bought a different brand. He said, "They (the horses) won't know the difference! To prove me wrong, he extended his open palm with the "other brand cookie" to one of our young fillies who happily gobbled it up. Within a couple seconds, she made a sour face and promptly spit out the inferior "cookie". We received a similar response from everyone else in the barn.
