Dogtra e-fence wire and repair parts

The 500 ft Dogtra boundary wire is what you'll need if you're expanding an existing loop or replacing a damaged section. The EF-3500 E-Fence expansion kit bundles extra parts for adding to an E-Fence 3500 layout.

Every join in the loop should be sealed. The waterproof splice kit comes as a 4 pack, so you've got spares for future repairs.

Protecting the transmitter

The fence transmitter is plugged in all year, which makes it vulnerable to power spikes from storms. The Dogtra surge protector is made for the EF-3000, EF-3000 Gold and E-Fence 3500. If you've lost the power supply, the BC25V500 charger fits the E-Fence series transmitter.

Finding a break in the wire

If the transmitter's loop light or alarm says the circuit is broken, walk the boundary and look for fresh digging, mower damage or anywhere the wire crosses a driveway. Most breaks are in the first few inches of soil. Once you've found it, strip both ends, join them and seal the joint with a waterproof splice. Re-test before you let the dogs out.

Planning a bigger area

Longer loops need more wire and sometimes a higher field setting on the transmitter. Twist the lead-in wire from the transmitter to the boundary so that section doesn't trigger the collar. The E-Fence manuals on Dogtra's own site cover layouts and settings in detail.

How much wire do I need?

Walk the boundary with a measuring wheel, or measure it on a satellite map, then add the run from the transmitter out to the loop. A single 500 ft roll makes a loop of roughly 125 by 125 feet, which is about a third of an acre. For bigger properties, order extra rolls and a couple of spare splices. It's better to have a little wire left over than to come up 20 feet short halfway round.
