Perimeter Collar Guide
Searching for a "perimeter collar" returns three unrelated product categories. Identifying which one you actually need takes about a minute.

Quick answer
"Perimeter collar" is a generic term for any collar that enforces a boundary. In practice it refers to one of three things: an in-ground fence receiver that reads a buried wire, a wireless fence receiver that reads a radio field, or a GPS collar that compares satellite position to a mapped boundary. It is also used as a replacement-part search when an existing system's collar has failed.
Identify which perimeter collar you need
Do you already own a system?
Then you need a compatible replacement receiver from the same product family — find the transmitter's model number first.
Is there a wire buried around your yard?
You need an in-ground fence receiver. See our underground dog fence collar guide.
Is there a plug-in transmitter box indoors and no wire?
You need a wireless fence receiver matched to that transmitter.
Is there no hardware at all?
You are choosing a system, not a collar. Start with the fence type comparison.
How the three types compare
| Type | Boundary source | Portable | Recurring cost | Typical use |
|---|---|---|---|---|
| In-ground receiver | Buried wire signal | No | None | Permanent, precisely shaped boundaries |
| Wireless receiver | Radio field from a transmitter | Yes | None | Simple circular yards |
| GPS perimeter collar | Satellite position vs a map | Yes | Often | Large, custom or travelling boundaries |
Buying a replacement collar
- Match the transmitter model, not just the brand — families change across generations.
- Check whether your system's boundary width is set on the collar or the transmitter.
- Verify the battery format before ordering; module types are easy to get wrong.
- Re-run a short boundary refresher with a new collar, even for an experienced dog.
