Does your dog bark at the window at people or animals passing by your home?
Your dog is under stress. It is suffering from barrier frustration and will become more aggressive in time.
You need to eliminate your dog’s aggression by making it go lay down and play with a chew toy. Begin by training your dog to go lay down on a pillow. Leave a chew toy there as a marker for your dog. Next make your dog go lay down whenever you recognize that it is going to begin barking at the window. You are attempting to train your dog to go lay down whenever it is motivated to bark at the window thereby replacing barking at the window with go lay down. 🙂
