Description

The Dogtra EF-3500 E-Fence expansion kit bundles what you need to extend your fence: a 500 ft spool of wire, 50 training flags and 4 waterproof splices.

If you’re making your fenced area bigger, this saves ordering three separate items. The wire extends the loop, the flags mark the new line for training, and the splices seal the joins where the new wire meets the old.

Will the Dogtra EF-3500 E-Fence Expansion Kit fit?

It’s for the EF-3500 and EF-3500 Gold.

Planning the layout

Walk the boundary with flags first. It’s easier to move a flag than a buried wire.

Splicing and burying

Shallow is fine for most soil. Just keep the wire away from mower blades and edging tools.

Finding a break

Breaks usually happen at old splices or where wire crosses hard surfaces. Check those spots first.

Teaching the boundary

Take the flags down gradually once your dog respects the line. Rushing this step is the most common mistake.

Fence parts we stock

The 500 ft boundary wire extends or repairs a loop. The waterproof splice kit seals joins. The EF-3500 expansion kit bundles wire, flags and splices. The surge protector guards the transmitter, and the BC25V500 powers it.

Protecting the transmitter

Check the transmitter’s loop light now and then. It’s the quickest way to know the fence is working before you let the dogs out. Dogtra’s manuals are on Dogtra’s website.

Ordering tips

If you train most days, buy a spare while you’re here. A second clip, antenna, cap or set of points tucked into the kit bag can save a whole session when something gets lost or broken far from home and the nearest shop that stocks Dogtra parts is a long drive away. Worth it.

Why genuine

It’s the real thing. We only stock genuine Dogtra parts, and if you’re unsure about fit, ask us before you order and we’ll check it against your model.
