Review on 🐶 Zigzagmars Ultrasonic Dog Bark Deterrent - LCD Display- Up to 50 FT Range by Ashley Andrews

So I have a 13 year old poodle. When he's in the backyard, he barks at every living thing that moves all the time. He loves protecting his house from people walking the path behind my house. He also never got used to the fact that I left him alone and barked inconsolably for an average of 60 to 120 seconds after I closed the door. When I saw this barking device I thought it might be worth a try. I had small hopes that this would make a difference, but I'm surprised and happy to honestly say it couldn't have worked much better! The results came very quickly. Within the first day of turning it on, the barking almost completely stopped. Now he more or less just grunts at the sound and when I leave he doesn't bark heartbroken anymore! I'm really surprised how well it worked! I can't say this works on all dogs, I can only say it works well on mine. Happy with the purchase ❤️!
