That is exactly like Tia. In fact at puppy classes sitting still is a problem because of the wiggles, I love it and so does everyone she meets. We wiggle out the door, wiggle at everyone she sees even if they are across the street, wiggle at any dog and especially big wiggles at her family. This is one of my fav things about her. I think it shows a really charming, fun personality.
So heres to all you wigglers.
