Dogs (like rats) are multitalented but they are also not very smart the way humans are. A recent book, devoted to the intelligence of dogs, is 250+ pages long (Stanley Coren, The Intelligence of Dogs: A Guide to the Thoughts, Emotions, and Inner Lives of Our Canine Companions, 1994). Interestingly, despite careful qualifications by Coren regarding definitions, the ranking of breeds by intelligence literally made newspaper headlines. We are obviously fascinated by the notion that dogs - or at least certain breeds of dog - might, just might, be really, really smart. It all makes as much sense as evaluating humans on our ability to sniff for bombs or echo-locate.
