Ultrasonic Dog Repeller,
Verified Purchase(What is this?)
This review is from: Mammoth XT Ultrasonic Dog & Fox Repeller / Silencer / Deterrent / Bark Stopper (Misc.)
i bought this product to try to stop my dog barking everytime she saw another dog ,even in the distance. It did work initially then she developed the ability to ignore it completely. I found if I used it occasionally it proved to be more effective. It causes a distraction for a few seconds.
