<div dir="ltr">I think the idea here is to create a situation where the dog makes a decision based on some form of reasoning, in this case after excluding the first 2 roads the unavoidable conclusion is that the master has followed the 3 roads. This indeed would show some form of high reasoning in the dog. The details are not so important. Neil deGrasse Tyson does a similar experiment in this video, where Chaser the dog finds a stuffed animal that never saw before (Darwin) by excluding all the other possibilities:<div>

<font size="1">In Michio Kaku's book, The Future of the Mind, there is a puzzle (page 303) that makes no sense to me. Plutarch and Pliny have written about it, Montaigne, John Locke, George Berkeley, and Aquinas have opined about it and no one is happy with any solution to whether the dog can think/abstract. Here it is:<br>
<br></font></div><div class="gmail_default" style="font-family:comic sans ms,sans-serif;font-size:large;color:rgb(11,83,148)"><font size="1">There are three roads and the dog's master has gone down one of them. The dog sniffs along two of them, finding no scent of his master, and so, without sniffing (!), takes the third. Did he think?<br>
<br></font></div><div class="gmail_default" style="font-family:comic sans ms,sans-serif;font-size:large;color:rgb(11,83,148)"><font size="1">IMO: flawed puzzle. A dog simply would not do this. Saying 'but if he did' begs the question. A creature of scent, he would sniff the third trail just as he had the first two. To a dog, smell overrides the other senses. Another flaw seems to be this: how did the dog 'know' his master went down any of the roads? But this is not important.<br>
