I love having smart dogs, but they are a lot of work. We have to keep reminding them about who is the boss!
I've met a few pretty dumb dogs. One was a cocker spaniel who got lost anytime she got outside her front door! She was a neighborhood joke. Another was a Bernese Mountain dog who couldn't do anything except sleep. He didn't know what to do with balls or any of his toys. He was a cute, furry lump of a dog!
