I hope you're just saying that to be mean.
Because dogs are smart.
Especially compared to cats.
actually one of my dogs is extremely dull.
and my cat was awesome. she spent the whole day hiding from us in our basement in the rafters when the dog came, and once he chased her around until she pulled a matrix move: jumped up and off of our window, changed direction, did a half flip during the 180, landed on our couch, ran along the couch, jumped off, and bolted for the basement.
and i was like what the stuff how did she do that.
