One Quandry Solved and another to solve

Well I've decided that I'll knit the socks at work because they are relatively simple and I can pick up and put down in between interuptions. I'll do the Alice Starmore aran gansey at home with a bit of WRS on the side.

The quandry I am now faced with is Ish. For some reason she seems to spend inordinate amounts of time licking me. Now I have no problem with that per se. I mean I'd rather having her licking than nibbling as I'm kind of attached to my skin and blood but I just wonder if it is something I should be worrying about. Any ideas anyone?
