I just wanted to respond to the initial statement posted by my lovely fiance... Gappie which is short for Gap Wedge (golf term...look it up). She loves to jump at windows due to passing birds or people or squirrels, pretty much anything that is in eye sight. If she were to ever get free from the house or leash she would run and run and run forever. But I was able to teach her to roll over in about 5 minutes, and I have to say she is the smartest dog I have ever trained.
