Welcome to YT. Don't worry about your doggy, count your blessings. My Nikko is the noisiest little boy around!! He barks at everything and lately has been barking more than ever. He barks at his toys, he barks to get my attention, he barks when you leave him in another room and he wants you to come over to him. He even barks at the curtains when they move if the window is open. I remember being like you when I first brought him home at 3 months old. He was so quiet, I worried that there was something wrong with him. Oh how I miss those quiet old days!!
