The original wireless dog fence — covers up to 1/2 acre with no wire to bury
The PetSafe PIF-300 is the fence that started the wireless containment category, and with over 25,000 five-star ratings it’s still one of the most trusted systems on the market. Plug the transmitter into any standard indoor outlet, set the boundary radius, put the collar on your dog, and you have a working fence. No trenches, no wire, no installation tools. If you can plug in a lamp, you can set up the PIF-300.
The transmitter broadcasts a circular radio signal up to 90 feet in every direction — 180 feet across, up to 1/2 acre — through walls, floors, and typical household obstructions. Position it in a garage, closet, or shelf near the area you want to contain. Your dog wears a lightweight waterproof receiver collar that detects the boundary signal. As he approaches the edge, the collar warns him with a beep. If he keeps going, a brief static correction follows. With consistent training over about two weeks, most dogs learn the boundary and stop testing it.
Coverage, boundary, and signal
The boundary is always circular — the transmitter is the center, and the signal radiates outward equally in all directions. You can adjust the radius smaller by turning the range knob, but you cannot change the shape. This makes the PIF-300 ideal for flat, open yards where a circular boundary works with your layout. If your yard is oddly shaped, has significant terrain changes, or you need to follow a property line, an underground fence will give you more flexibility.
The signal transmits reliably through most walls and household obstructions, but dense metal structures, stucco, or heavily wooded areas near the perimeter can affect consistency. Position the transmitter at least 3 feet away from metal objects for best performance. If you need more than 1/2 acre of coverage, a second transmitter can be overlapped with the first to expand the containment area — just ensure the two boundary circles overlap by at least 30 feet.
You can also use the system to block off areas within your yard — gardens, pools, or anywhere else you don’t want your dog to go. The transmitter can be repositioned to create a smaller exclusion zone rather than a full-yard boundary.
Add more dogs with additional collars
The PIF-300 supports an unlimited number of dogs — each wearing their own additional PIF-275 receiver collar. Each collar is set up independently so you can dial in the right correction level for each dog. The collar is small, lightweight, waterproof, and runs on an easy-to-replace 3V battery. Five levels of static correction plus tone-only mode.
Extend your coverage with a second transmitter
Need more than 1/2 acre? Add an extra IF-100 transmitter and overlap the two boundary areas to expand your coverage. You can also use a second transmitter to create a completely separate containment zone in a different area of your property.
Portable containment anywhere you go
Because there’s no buried wire, the PIF-300 packs up and goes with you. RV trips, cabin rentals, family visits — wherever there’s an outlet, you have a fence. Just plug in, re-flag the boundary area with the included training flags so your dog has a visual reminder of the new boundary, and you’re set. Note that metal buildings or vehicle interiors can reduce the maximum boundary size when using the system portably.
PIF-300 vs. Stay & Play — which should you choose?
The PIF-300 and the Stay & Play use the same basic technology but differ in two key ways: the PIF-300 covers 1/2 acre with a disposable battery collar, while the Stay & Play covers 3/4 acre with a rechargeable collar. If you have a larger yard or want to avoid replacing batteries, the Stay & Play is worth the upgrade. If 1/2 acre is plenty and you prefer the simplicity of a disposable battery, the PIF-300 is the right choice.

Customer Reviews
- Checks all of the boxes.By:Frederick Brol
I love this product. I can now let our dog out and she can run all around our property without me hanging onto her, or being hooked to a cable. She gets so much exercise running, when she comes it she's much more relaxed and less hyper. Would recommend any time. (3/8/2023)- Keeps them in the yard.By:David Buck
My wife has been using this wireless fence for the last three years, and we've never had a problem with our 6 dogs getting out of the yard. It all started when our lab, Gracie, kept digging up our neighbor's flowers. The fence was easy to set up and stopped her from wondering off. Now when we get a new dog, we immediately get another collar to go along with them. (5/20/2014)
