Compulsive licking

Tyler has many compulsive behaviors. One of these is licking. He licks the kitchen floor (half of his shed hairs are in his belly for this reason). He licks the carpet. He licks my boyfriend's head in a rhythmic, meticulous pattern and will not stop until he has "washed" every nook and cranny behind the ears, around the eyebrows, etc. He licks my legs when I emerge from the shower. He also eats just about anything he finds that will fit in his mouth. His favorite thing is tissue paper he finds in the trash and I’ve gotten really paranoid about that since I started using this nasal spray which contains a steroid (for allergies). So… those tissues go in the tall trash can! Cause I don’t know what happens to a pug on steroids, but would rather not find out for his sake and for ours.
