re: Invisible(underground) dog fences-What features should I look for in a good one?

One more thing about he one we bought. There is literally zero hassle to installing it. You just plug in the base at what will be the center of your dog's range and put the collar on the dog. My wife had ours up and running before I even got home from work. As for the dog, he only tested it once that first day and now he will turn back soon as he hears that beep.
