Hidden Fence was founded by Navy veteran Lester Pullen and has been serving homeowners since 1996. Before launching the company, Lester worked with Invisible Fence® systems and saw firsthand the limitations of systems that required service calls for adjustments. That experience led to a better approach, systems designed to give owners more control, with hundreds of adjustable levels that allow each setup to be tailored to the individual dog.

We combine advanced Pet Stop® technology with a gentle, humane training approach to ensure your dog understands their boundaries safely and effectively.

In 2001, Lester Pullen helped develop, and then was the first to introduce a gentle, low-stress, reward-based training approach that set a new standard and changed the industry for how dogs are trained on containment systems. Today we call it the Gentle Steps™ method.
