Check out the thread "Do they ever stop following you?" Posted by Blabbyb... I've copied her question below and the short answer is - No they don't stop following you, this is common behavior regardless of whether they are a puppy or an adult... but there are lot's of good answers to Blabbyb's question on that thread. Enjoy your "shadow who loves you so much she does not want you out of her sight!!

Pita (15 weeks) follows my every move. As much as I love her, I wish she didn't follow me everywhere. She will even get up to follow me if she is sleeping and then I leave the room. This makes me feel guilty for disturbing her sleep! Do any of your yorkies do this and is there an age that they stop?
