Apropos of the discussion Jabari/Liz and I were having about dominance in dogs and how it relates to intelligence, I found this interesting site where you can assess the IQ of your dog. Great fun!
Actually, Penny is part of an ongoing research project - forget which local institution, think it might be RMIT - where humans living with dogs fill in a canine personality assessment a couple of times a year. The researcher is trying to discover whether humans can in fact make a consistenly accurate assessment of this kind. To be in it you have to have two people who live with the dog and then the two fill in the personality assessment without consulting each other - so as not to be influenced by what the other thinks. I'm looking forward to hearing the result of the study a couple of years down the track.
