Addendum: See the informative comment below by John Protevi on the substance of Balko’s column—the fallibility of drug-sniffing dogs (and their trainers), and the resulting miscarriages of justice.
My late cat Mr. H came to be very good at knowing when I was finished playing a piece on the piano. I have recordings in which, a second or two after the piano stops, Mr. H’s characteristic yowl supplies a coda. One might almost think he had a grasp of musical form, but I’m quite sure that his grasp was rather of my habits than of anything to do with music. He had likely picked up something in my posture that correlated with finishing a piece, something distinctive enough that he was rarely deceived by pauses during a piece.
I was reminded of this in reading first a
column by Radley Balko on police dogs and then some extracts from a book cited by Balko, Alexandra Horowitz’s
Inside of a dog (the title alludes to a Groucho Marx
joke, in case you’re wondering). Horowitz describes experiments in which domestic canines, when humans are present, tend to do much worse than their wild cousins.
Tested on their ability to, say, get a bit of food in a well-closed container, wolves keep trying and trying, and if the test is not rigged they eventually succeed through trial and error. Dogs, by contrast, tend to go at the container only until it appears that it won’t easily be opened. Then they look at any person in the room and begin a variety of attention-getting and solicitation behaviors until the person relents and helps them get into the box (180).
Anyone who has a dog or cat will recognize the phenomenon. Are dogs, then, dumber than wolves? Horowitz doesn’t think so.
