Enzo has always been a licker but starting last night he seems to be licking excessively, on me, himself, the couch. None of this is by itself unusual. It is just the amount and frequency of licking. He is a 1 year old spoo. I looked at his mouth and his teeth seem fine. He does chew up his toys and I wonder if he got some fuzz in his throat. I can't see any problems and I checked his muzzle, ears, mouth. He doesn't seem to be hurting. I gave him a dentastick, and he is drinking water and eating ok. It just seems odd. Or may-be I am just being paranoid. Any ideas?
