Super Bowl 2012 commercials: Smartest dog

“Man’s Best Friend” (Doritos, 0:30, second quarter):

Sometimes people give dogs treats so they’ll behave. Well, that cuts both ways. The household cat, Fluffy, has gone missing, and the master of the house suspects that his dog is involved, as he catches his pooch burying the feline’s collar in a flower bed. To keep the man quiet, the dog gives him a steady supply of Doritos…and the cat is never found.
