Kathy Coon has taken a clever idea and developed it scientifically. In this 10-step test you can determine your dog's abiolity to remember an object's location, to adapt to new situations, skill at problem solving...no special equipment is needed. Test will take 15 minutes!
Yeah... plays fast and loose with the notion of 'standardised' and some of the tests are culturally irrelevant if a dog hasn't been taught object play. Popular psychology it may be, but a chichi ain't a 2 and a bulldog ain't an 8. Fun, sure, but certainly not scientific.
