During the ‘70s and ‘80s, electronic dog fencing was controlled by one company until their patent expired in 1989 when the door was flung open for competitors. Most of these new companies copiedexisting technology, but two entrepreneurs named Bob Slattery and Bob Wolfe, the founders of ReachUSA® and ValPak of Cincinnati®, saw a genuine opportunity to make something better, an entirely different kind of pet fencing product. These two men contacted the largest radar detection company in America. Together, they engineered a dog fence that incorporated a variety of dynamic new features. Their methodology was simple. They took a fresh approach to pet containment, and the result was a state-of-the-art system.
