I love the strong and powerful look of breeds such as Belgian Malinois and Dutch shepherd, you can see those muscles rippling under their short fur and it's such a turn on. I like sharp, wolf like features like upright ears and pointed nose, but I think dobies and rotties are hot as hell too.
Love the short fur where you can see their big fat sheath and balls. Same goes for stallions; muscular black furred and with their fat sheath on full display. Yum.
