I have read about a radio collar used with dogs. It sends out a radio signal. As long as the collar is within range of the signal, nothing happens. If the collar is taken out of range, it sends a shock. The minimal range though was a radius of 30 ft or so. Has anyone seen a collar that works like this to maintain a close range, such as a 10 ft radius around me? I have found a vibrating device that stops vibrating at about 20 ft, but I want the opposite, no response within the radius, and it goes off outside the radius.
