Pet Safe Instant Wireless Dog Containment Fence System PIF-300
Product Review (submitted on July 16, 2012):
We bought ours at our local Rural King several years ago and it still does an amazing job. We have a large dog outside and he has plenty of room around the outside of our home to romp. Also have a collar on our inside dog so we can let him go outside to do his business and not worry about him going down to the road or wandering off to a neighbors. We've taken it to my wifes parents so he could run around their place without worrying about him. We love it and would recommend it to anyone.
