I'm going to have to join the 'cheaters' and say mutts. Even looking at my two current dogs, they couldn't be more different and I couldn't be happier about that.
Even if you ignore temperament/behaviour and just look at aesthetics, I can't say for certain that I have a 'type' that I prefer. I mean, there's a pretty significant difference between a sleek doberman and a burly mastiff, but both are breeds that I'm head-over-heels enamored with.
There's a small handful of breeds I'm certain I want to live with at some point in my life and so many more that I would like to research more for consideration.
