I would have to honestly say Chihuahuas (sp). My sisters is so annoying. All she does is whine. But I am not a small dog person at all. I prefer giant dogs.
I have avoided answering this cause I know there are a few owners of the breed here! Mine would have to be poodles small large any size really. I just don't like them, I think they are the "prissy" breed! Everyone i've met has had the biggest attitude. Maybe I haven't met the right one yet but at all the shows I have been to they have all acted like that.
No offense taken! In defense though, I will say my 2 have very much surprised many people who had pre-conceived ideas of the breed. Their favorite activities are retrieving, swimming, and just plain romping around raising holy heck! I always laugh when someone says something along the lines of "Wow, they really are regular dogs!". My brother who is about 6'4" and 250+ lbs is now seriously considering getting a standard poodle & he was one of those who said, "What do you mean you're getting a poodle! They are such foo-foo, prissy prima donnas!".
I'm sure they are good dogs but i'm going by my experiance of them and what i've seen of them. 99% of the ones i've been around were all show dogs spoiled rotten, that may be the reason. I know not all poodles are like that, just something about them that just doesn't tickle my fancy.
That is what is so great about the canine world - there is a vast enough variety that there is the "right" breed(s) for everyone who loves furry, 4 legged companions with a cold nose and large heart!
