History of the Dog Fence

Richard Peck, a traveling salesman, invented what we now know as a dog fence in 1971.  Peck was troubled by seeing all the stray dogs that ended up on the roads and looked for ways that owners could keep their dog inside their property without an expensive and visually obtrusive fence.  Working with an electrical engineer, Peck came up with the idea of using boundary wires in conjunction with a receiver collar to keep a dog contained.  Peck patented his invention in U.S. Patent Number 3,753,421, entitled ‘Method and Apparatus for Controlling an Animal.’  Peck called his invention , Stay-Put but the product did not take off until Peck sold it.

In 1976 John Purtell purchased the patent from Peck and changed the name to Invisible Fence*, building the company up until he sold it in 1993.

In the 1990’s as the Peck patent expired, many new companies entered the industry, including Dog Watch*, Dog Stop*, Contain a Pet* and smaller regional independent installers to provide competition to Invisible Fence.  Companies also started to produce DIY kits to provide cheaper Invisible Fence* alternatives.

Invisible Fence was bought and sold several more times and is now owned by Radio Systems Corporation, which dominates the industry.  Invisible Fence’s parent also makes the DIY brands Innotek and PetSafe which you will use in your installation.

What radio frequencies do the electric dog fences work on? I am getting radio interference on the AM radio band (600 kHz) from my neighbor who is using an Innotek wire fence a few hundred yards away. If the dog fence is putting out this much RFI (radio frequency interference) is it defective? Perhaps a lightning hit has changed something?

ADMIN – Hi Barry,

The Innotek systems do indeed work at 600 Khz – but the range is very limited. Generally using a regular AM radio you don’t can’t hear signal once you are ten yards away. It is possible that the neighbor has his system set up with an unusually wide boundary, but even then you should not hear anything at 100 yards. Lightning damage is unlikely to be the culprit – as that will usually make the unit completely stop working. Ask the neighbor to switch off the fence for a few minutes and see if the interference stops.
