Suzi is excatly the same way
especially if we have been gone a little while. She likes to kiss me behind the ears. LOL. She's a fast little kisser too. But, after a while of sloppy kissess we tell her no more, and she will stop. Suzi has always been a super kisser , we love her so much for her great temperment and love she brings to out family.
I read somewhere that when a dog gives kisses it give them a endorphine realse, making them feel really good
