LOL! Want a smart dog, get a German Shephard or a Poodle.
Smartest dogs I've ever had - a GS and a pekepoo. My daughter has a Bichon Frise - too smart!!! Into everything even after a $1500 stint at boot camp! Actually, I think he knows he's Alpha in the household. I wouldn't put up with him for five minutes.
My experience for smarts has been Shelties and Bostons.
