Designer David McCandless made this neat matrix mapping dog breeds according to factors like popularity, intelligence, longevity, or cost. Poor bulldog.
I can't agree that Westie's are dumb as noted on this cart. They are really good at getting what they want, either form their human or on their own. They are also pretty easy to train, but can be incredibly stubborn at times. A delightful combination of personality and energy, and a fantastic companion.
