my dog is 16-17 we don't really know and he is rather blind!but he can still smell his way to our toes!and lick them!vut he doesn't seem to like clean feet,he won't lick if you just got out of the shower.his name is boots.I would show u a piccy of him but i dont know how.
oh and by the way my freinds rabbit will kiss her hand when she says kiss and stop when she sas stop!isnt that adorable and she won't do it to anyone else she'll just bit them.
