Lucky has decided he likes to make little dreadlocks on his ears.
It's sort of funny, but actually it does concern me as something boredom-related or possibly obsessive-compulsive. He finds a piece of hair that he can grab with his mouth, then he starts working at it with his saliva, chewing on it and sucking on it until it becomes thicker and thicker. I have already cut off a few of them; the first one was three inches long!
I really want to get him to stop doing this sooner rather than later because I'm afraid he will just develop a habit that will be hard to break.
Has anyone else's dog done this?
