Cats. They don't need alot of attention, they don't stick their noses by your ass to smell it, they don't jump on you when you come home and get all up in your business, and they're more fun to watch.
Of course my cat is spoiled rotten so he needs his attention, but other than that we have a good understanding of one another. Not that I don't like dogs mind you, I mean obedient ones are cool.
