Thats interesting I have used it in the back yard to retrain an escape dog..... She hit that once and I could her her yelp from the other side of the house... she tested it in another area.... that did it. I never had to switch it on again. yep the city.

I used a remote collar which worked very well and didnt require any fencing or posts just a small unit in the center of the dog yard (a circular area) and a collar for the dog. There is a similar one that uses a burried wire in the ground as a barier which can be made any shape or size. Unfortunately neither of these will keep anything out.......
