The reason I'm so shocked is that I'd swear she has OCD (Obsessive Compulsive Behavior) because she never stops licking.
Herself, the couch, carpet, me, Buddy, floors, you name it, and her tongue’s been on it! And since her tongue is outside of her mouth more than it is inside I thought it was weird that I've had her for almost 6 years and only just now noticing this spot.

I tried taking a closer look at it but didn't have any success. Have you ever tried to grab a hold of your dogs tongue and look at it?? It's not all that easy!
