I'v wondered, would those noise fence devices that work for dogs also work on vermin like raccoons or skunks?
Doesn't that only work on dogs wearing a special collar?
Those shock the animal. I know nothing of these noise fences.
Noise fences are often used in conjunction with shock collars. The idea is to get the dog to associate the beeping collar with getting shocked if it keeps going towards the line. I used a shocker on my dog for a little while with an audible "beep" sound that would go off a second before the shock happens. Now, all it takes is the sound of my voice to stop him from running off after some wild creature. He associates "stop!!" with the beep and remembers what happens if he disregards the beep. Fucker has been within inches of getting his ass flattened by cars more than a few times when running after a chipmunk or cat, so for me it was a good trade off for looking like a statist prick using shock treatment on him.
