I've read that border collies and poodles are the smartest dogs. I've had chihuahuas for years and I think that they are pretty smart. I and my brother were once outsmarted by a chihuahua, we were chasing her around a coffee table, I was at one end and my brother at the other. We thought we had her trapped but then she made her getaway from behind the couch. I just stood there stunned because making a getaway from behind the couch would never have occurred to me.
