You might want to try a breed selector quiz to see what they come up with. I just tried Animal Planet's and while it includes a lot of pretty obscure breeds, their top twenty was a pretty good match to what sort of dog I think would be a good fit for our household (mostly medium-sized herders and terriers/bull breeds and very few hounds).

I adore corgis, although you have to be careful of their backs and I've heard that food aggression/guarding can be an issue with them.
