Review on Deppet Ultrasonic Frequencies Immune Proof Rechargeable by Satish Simone

My five year old terrier was attacked by an adult Shepherd Mix Collie when he was nine months old. We were at a local park and the other dog was not on a leash. We were able to separate the dogs before any major damage was done, but my dog immediately developed aggressive, defensive behavior when he saw another dog. I have tried stun collars and vibrating collars with no success. The Deppet anti-bark device worked when I first tried it and is still working months later. Pressing the button immediately grabs my dog's attention, followed by a "no" command prompting him to stop the unwanted behavior. It took her about 4-7 days without the device to just respond to the "no" command. Very happy with the purchase of the anti bark device. It is a very fast and efficient learning tool.
