SOMETIMES it just means its itchy too 
Licking at their rectums a lot can also be a sign of them trying to express the glands, just as the scooting across the floor is the dogger's attempt to empty the anal sacks. Even frequent tail chasing can be a sign of full glands.

Auggie is almost 10 months old and has never had this done. He never scoots on his butt. Is that the only sign. Please tell me there are chi's that don't need this as we only hear from those who do :roll:
