Invisible Fence Collars & Replacement Receivers

Lost a collar, adding a new dog, or need a spare? This is every invisible fence collar and replacement receiver we carry, sorted by the fence it works with. A receiver only works with its own brand and system, so match the collar to your transmitter.

Before you order

  • Check the brand and model on your transmitter (the indoor box). For Invisible Fence brand systems, check whether your fence runs at 7K or 10K.
  • Battery collars need fresh batteries every few months. Rechargeable collars need a charge every few weeks.
  • Fit the collar snug enough that both contact points touch skin.

Invisible Fence Collars & Replacement Receivers FAQs

Can I buy a replacement Invisible Fence collar without going through the dealer?

Yes. The Perimeter Technologies replacement collar works with Invisible Fence brand systems that use R21 or R51 collars. Pick 7K or 10K to match your transmitter.

Will a PetSafe collar work with an Invisible Fence or SportDOG fence?

No. Each brand uses its own signal, so a receiver only works with its own brand's transmitter, and often only with specific models. Use the compatibility table above, or call us with your transmitter model and we'll match it.

How do I know if my fence collar is 7K or 10K?

The frequency is usually printed on the transmitter label or in your installer's paperwork. If you're unsure, call 737-215-3211 and we'll help you check before you order.

Why did my fence collar stop working?

The most common cause is a dead battery. Next are loose or worn contact points, and a break in the boundary wire (the transmitter will usually alarm). Replace the battery or charge the collar first. If it still doesn't beep at the boundary, the receiver may need replacing.
