I don't know, but Dusty doesn't give kisses either! Some people think it's so petty, but it really bothers me. At the best he'll like stick his tongue out real quick and make a kissing motion, but it never actually touches me. I think he's kissed me probably 2-3 times. I get so exctied when he does. My husband says that's the right kind of dog because he can't stand dog kisses. lol.
