Based on looks alone, (not to mention all the other reasons) A Doberman. To me, there is no dog more handsome than the elegant and utilitarian Doberman Pinscher. There are a lot of handsome dogs though. I love the look of a good GSD, Rhodesian Ridgebacks are handsome as can be, Weims, Vizslas...I love their look too. And a whole lot more, but my #1 pick is a good Doberman.
