Dobermans of course.........and great danes have always fascinated me as well. I don't know if they would fit my life, but I love their friendly nature and their looks alot.
I would consider alot of different types of athletic looking dogs if they would fit into our life well.
I have posted this before, but I tend to be drawn to short haired well built, toned dogs where you can see and appreciate their physique. I LOVE to see a well built dog running with their muscles rippling........it is a thing of beauty to me
