I am constantly seeing reference made to a persons dog/pet responding to a BF vocalization or smell or encounter. Is this really significant? It seems that it is mentioned, most of the time, as proof that something happened and, of course, we can't question the dog to find what he reacted to.
I play a harmonica. If a dog is around when I play, they will always respond. Usually with a howl and sometimes with a whimper. Cats will usually leave the room, blinking their eyes. I have always assumed that there were sounds I couldn't hear that the dog could. I also play a guitar and sing badly. I never get a response from the guitar or my voice.
So the point is, why are we always stating how our dog acted when they hear a vocalization. Maybe just another example of us trying to personify or intelligencize an animal.
