Review on 🐶 VOSOV Ultrasonic Dog Barking Control Device: Stop Barking with a Lightweight Dog Whistle" by Christine Rogers

I have a 50 lb, 9 year old smooth collie that barks very loudly like Lassie. Last year she started barking more and more. She barks at people when I take her for a walk, barks when she sees other dogs, sometimes barks at cars going by, people coming through the door, etc. She is very friendly and just says hello, but the barking has gotten worse and really annoying. I bought this device after trying 2 different non-shock collars I bought from Revain and returned because they just didn't work. This device worked in less than a day. She doesn't like the sound I can't hear. She met two of her canine friends on a walk this morning and barked madly when she greeted them. Two other dogs barked loudly at her. Not a single bark in response! Both dog walkers asked me where I bought the device after seeing the results so they could buy it. One aimed at his dog, which immediately stopped barking. I highly recommend this ultrasound machine.
