Territorial Paranoia

It’s driving me crazy. 10 month Akita with strong innate guarding instincts.

We live at a very popular intersection in our neighborhood that will constantly have dogs/people walking by. Even occasionally at night.

2-3 months ago, she was fine watching everything go by at the window. Now she aggressively barks at any dog/person that walks by the house. If you close the blinds and block the gaps with chairs, she barks at the sound of anyone outside. She even recognizes the sound of a car stopping outside the house and will bark. This is all worse at night, especially for us. If she’s outside on leash, it’s when worse reactivity if someone were to come by.

My family cannot get sleep. It’s impacting my work and I am losing patience with her and hate that it’s getting to that point. She doesn’t respond to leash pressure, food, play, or anything when she’s in a guard mode.

I’ve tried positive reinforcement but it’s hard because she very consistently gets triggered regardless of any distraction. She doesn’t listen in the slightest post-trigger. She’s not food or play motivated at this point either. I try to pretend to look out the window to make her seem I’m in charge and handling it but I can’t always stand by the front window. I’ve tried prong use to correct her but I feel like I can’t figure out how to direct her to acceptable behavior.

Any advice?
