'Rocco is approx. 4 years old and he constantly licks -- the air, the bed linens, clothing, me, my fiance...
Last year when I first signed on with MO, I posted about this, wondering if it could possibly be post traumatic stress syndrome, but never got any responses. I should have known then that they were behaving in an elitist fashion. *SIGH*
Anyway, back to subject at hand, I've recently read that Maltese will (sometimes) lick out of boredom. This may not be the answer in your case, but maybe if you try distracting Maxi from licking, you'll be able to nip the problem in the bud. Good luck!
