I looked at your website and saw a picture of Piper's brother (littermate), Rudy.  I can't believe how much they look alike, and it sounds like they have the same personality.  She lives to chase squirrels and lizards and likes to keep watch for armadillos at night time.  She also grumbles at all the commercials on TV with dogs and other animals, while Bailey and Molly don't pay any attention to them.  She is pure entertainment - life would be so dull without her.  Hope all is well with you and your Westies - their pictures at Christmas time were gorgeous.  Your groomer did a great job!  - Jeannie & Dick
