Review on Ultrasonic Dog Deterrent - Dog Dazer II by Samuel Browning

My neighbor German Shepherd calculated property every time I went out. I told my neighbors that the dog was becoming more aggressive, but they said I was wrong. My only defense was an invisible fence and I'm sorry but watching an adult 80lb dog pounce on me wasn't fun at all. I got a dazer and every time the dog was outside I would point in his direction and push the button. The dog immediately ran to the door and wanted to be let into the house. The neighbors must have noticed that because they built a fence between the courtyards. I'm glad we're still friends.
