Not only does Pawscout and the virtual leash work when you are at home, but it also serves as a safety net when you are out in public. We took Ruby to a forest preserve to test the tag away from home. One of us walked with Ruby and the other stayed with the phone and again it worked like a charm. If you are dog is off leash at a park or doggie beach, you will get a notification if they are more than 300 feet from you (and your phone). Sometimes we all get distracted.
