I like dogs, but I connect better with cats.
Inlaws had an unpredictable boxer that ran close to 200 lbs, it used to always want to lick my neck.
Never did that to anyone else, although it did bite a couple of relatives, whether they were deserving or not I don't know.
Never quite sure if it was licking out of affection or hunger, but I have to say knowing the nature of the dog... that used to freak me out quite a bit.
