If it comes down to it, you may want to get a second dog... solely for the purpose of nose licking. You'll need to get a good trainer so that the new dog will know its purpose is for licking noses. Make sure you get an ultra slobbery breed for this.
I think they have a certain working breed who are bred just to lick dry dog noses... Sinus Hounds. Yeah, look into getting one of those.
