Review on 🐶 ZelenDecor Anti Barking Device: Powerful Ultrasonic Dog Barking Deterrent, Rechargeable and Effective Control for Dogs (Black) by Lori Brock

I use mine for training. We have an Antollian Sheepdog/Great Pyrenees. she was small At almost 3 years old, she shows no behavioral improvement. I've tried everything! The tranquilizer collars didn't stop them, and neither did the voice commands. After just a few weeks, she hears much better and is almost completely exhausted from the car chase. We have a new Aussie puppy. After a week I just have to take it out of my pocket and it stops. I only use a short nudge for her but often have to use a longer nudge for a 3 year old. Hell, it even works on Tom's battle cats! As the instructions say, I name the pet I use it on. Although it affects all animals, they quickly find out which one is in trouble because I called their names.
