Review on Ultrasonic Dog Bark Deterrent Rechargeable by Dee Duran

Our 4-year-old Yorkie drives himself crazy every time a courier arrives at our house, or when a person or car drives by our house, or when a deer runs around our yard, or, God forbid an ant is crawling up to our mailbox 2 acres away. Do you understand. No kidding, this thing WORKS! From the very first time I pressed the button, it stopped and never made a sound again! I cannot praise it enough. That's great! We had just bought a fifth wheel and I was afraid to take it on a hike for fear it would disturb other campers. No longer! Works great. Update: Unfortunately, this started to lose its effect after about 2 weeks. She largely ignores the high-pitched tone and sometimes responds somehow to my "don't bark" command. I REALLY wanted this to work! 😂😂😂
