How do I know it is a scam? The dog does not do anything. It is a dog. It is not a pill that alters his brain's biochemistry that would calm him like a SSRI or a tranquilizer. The dog also is not a trained psychologist or behavioral therapist. It is a dog. It sits there and drools and perhaps barks. It is not going to talk him down or confront his feelings. In this case it is the same thing that could be accomplished by focusing on any inanimate object. So then it comes down to why have a dog over something like a plushie dog? You can do the same things with a plushie you do with a real dog in his case, and there would be only 2 differences. The first would be the plushie would react in a consistent manner, and the second is that the plushie is not against health codes. So why chose a dog? let us go to the extreme. Why not chose a skunk to do this with? Are we supposed to deal with a skunk because this guy cannot eat breakfast without his pal? No, the method is based upon an object that is not defined. So when you define the object you could put anything in there. So put something you can carry with you so you do not need to deal with this. This makes it a purposeful scam so he can carry his dog with him and skirt the rules. Now whether or not he is conscious of the scam, or he has deluded himself into thinking this is right does not make much difference to me.
