Pet Stop Pet Fencing.

Outdoor Solutions

Pennmar Pet Stop® provides Maryland with the highest quality invisible pet fencing systems. When installing your new hidden fence, we will bury a wire around the perimeter of your property with training flags to indicate where the new invisible boundary is. This wire begins and ends at a transmitter that is located at an indoor outlet for power, typically in a garage. Your pet will begin to wear a small customized receiver that is programmed for their individual size and temperament. Using our low-stress GentleSteps™ Training method, your pet is introduced to the boundary and is free to roam your property without worry of leaving in roughly 1-2 weeks.

Indoor Solutions

A common misconception about pet-containment systems is that they are only for use outdoors. Pet Stop brings the benefits of boundary setting indoors, too. We can help you end troublesome behavior on the expensive furniture, or unwanted eating habits in the kitchen. Our indoor boundaries can either be a wireless zone or custom wired with the line discreetly hidden. Our indoor system is accurate enough to create zones as small as only a few feet. The RoomWizard™ is offered in both wired and battery-operated versions.

GentleSteps Dog Fence Training.

We appropriately call our Pet Stop dog-training method GentleSteps. That’s exactly what it is: a series of gentle steps to effectively and humanely condition your dog to understand the new boundaries.

Custom-Designed Yard Layouts.

Full Perimeter Loop

Our most common layout installation is a Full Perimeter loop. This layout gives your pet free range to roam your yard but not leave it.

Figure 8 or “Pinch in”

Also common is the Figure 8 layout. It’s like the Full Perimeter loop, but with a pinch in the middle. This allows you to contain your dog in either the front yard or the back yard, it’s up to you.

Double loop or Banana Loop

The double Loop layout is used to contain only the front or back yard. It’s generally only used when your property’s geography won’t allow for installation around the whole property.


Small yards are no problem at all for Pet Stop technology. Our boundary fences offer settings to create a one-sided signal zone around the perimeter wire in order to maximize the amount of yard your pet can enjoy.

Current Owner Support.

Although we’re not affiliated with these companies, we do provide independent support and service for Invisible Fence® systems, as well as other pet containment systems such as DogWatch®, Innotek®, and Dog Guard®. If you’re an owner of an Invisible Fence® system, we can provide help with wire break repairs, general maintenance, and troubleshooting – just give us a call!
