I have had the same problem. Daisy and Diesel get so excited when they see anything outside (squirrels, cats, kids, mailman, etc).
One day in November, this man was walking his dogs down the block and decided to stop right in front of my house and watch my dogs go balistic. My husband went outside and asked the man to keep moving, of course he did not. Next thing you now, Diesel had broken the picture window, and would you belive the man still just stood there watching!! By the grace of God my Diesel was not hurt, the picture window was a different story.
We ended up replacing the glass with the industrial strength glass. The guys that installed the window could not believe that my dog had done this, they thought it was pretty funny!!
Still have not been able to break (no pun intended) of jumping on the window.
