I LOVE dog smell. Almost any dog, not just my dog. I think my favorite dog's smell is Max, one of my parents' GSDs. Second is Gavroche, though he doesn't have a strong odor. He does have one though, and it's very comforting for me.
I was at a friends house a couple weeks ago, and she has two dachshund puppies. I picked her dogs up and carried them up by my shoulders so I could smell them xD
