While this game works as a memory test, it isn't necessarily a test of intelligence. For example, Coile's dogs, who are Salukis, learned a long time ago that if they decide to, they don't have to search at all; they can just stand there and look tired, pitiful, and confused. If they do that, Coile will show them where the cookies are hidden. "The truth is that they've trained me." Now that's intelligence!
