I used to hate poodles, until my brother adopted one that he found in a park, shaking and covered with mange, and rehabilitated her. She was such a sweet little thing.
I've had two poodles (actually I still have the second). They're very smart, but the current one has some serious ADD. Fortunately I do too, so it kinda works out.
I love all dogs really. Even Chinese Crested and really, those are often hard to love.
If you're talking about Chows-Chows, that's the only breed I outright hate. When I was a kid, a neighbor had a couple of them, and those things where vicious. They'd bite you without a second thought.
