Invisible Fence® System Independent Service

While Pet Stop of Maryland is not associated in any way with Invisible Fence® company or the Invisible Fencing® brand, we do provide independent service on Invisible Fence® systems. As your local MD pet fencing experts, we can also provide service on most other dog fence systems, including PetSafe®, DogWatch®, etc. This is just one more example of how dedicated Pet Stop of Maryland is to keeping our local dogs and cats safe, happy and healthy.

If you're a current Invisible Fence® (or any other dog fence system) owner and you're looking to upgrade to the best pet fence in the industry, we have fantastic trade-in specials. We can also provide you with Invisible Fence® compatible batteries and dog collar receivers.

Invisible Fence® Compatible Products

Invisible Fence® Replacement Batteries

These are Invisible Fence® Power Cap® compatible batteries for the R-21® and R-51® computer collar. Designed to work flawlessly with your Invisible Fence® system, these batteries not only meet or exceed the IF® brand OEM specifications, but are also less expensive. Once again, these batteries are for the R-21® and R-51® computer collar. They WILL NOT work with the R22®.

Invisible Fence® Compatible Receiver Collars

Made to work with all Invisible Fence® brand transmitters (except the 800 series), this dog collar receiver is not only IF® compatible, but also has extra features not present on the IF® R-21 collar. Like all Pet Stop® products, this Invisible Fence® compatible receiver collar is made in the USA, and comes loaded with patented features, like:

  • Comfort Contacts® : used to cushion your dog’s neck in soft rubber

  • Ultra-Small and Light Weight : Only 1.1 ounces

Pet Stop® Products are
Invisible Fence® Compatible!

Did you know that most Pet Stop® dog fencing products are designed to be cross-compatible with Invisible Fence® systems? 

This is because Pet Stop® is made by pet fence industry leaders, including many former Invisible Fence® employees. In fact, Pet Stop's president, John Purtell is the FOUNDER of the original Invisible Fence® company, and Pet Stop's lead engineer, Scott Touchton, held the same title at Invisible Fence®.

With all of these experts, Pet Stop®'s brain trust has more experience in the pet containment field than any other electronic dog fencing brand!
