Arwen has the "I gotta bark at EVERYTHING" I can see from the windows (or even think I see) behavior down. And she's even happier, if she can wake up Misty and get her involved. *rolling eyes* She has to tell me everything going on outside of the house. She also has a certain tattle bark, on perceived misdeeds of Apollo and Aurora.
Misty's eyesight and hearing are diminishing. So unless Arwen gets her going, her days of nonstop watch dog are over.
Love All Life, Thank You For Posting! :)
