Dogtra E-FENCE 3500 In-Ground Dog Fence | Wired Underground Containment System, 500 ft Wire Included, Covers Up to 40 Acres, 8 Correction Levels

A physical fence can be jumped, dug under, or chewed through — and it changes how your whole property looks. The Dogtra E-FENCE 3500 in-ground dog fence gives your dog the run of your yard inside a boundary you design yourself. This wired underground containment system is a rechargeable, effective, hardwired pet fence built for mild to stubborn dispositioned dogs: bury the wire where YOU want the line — around the whole property, across the driveway, away from the garden and the pool — and your dog learns exactly where he can roam safely.

The E-FENCE 3500 kit arrives ready to install with 500 feet of 20-gauge underground fence wire and 50 boundary training flags, and with additional wire it expands to cover up to 40 acres — one of the largest coverage areas of any in-ground dog fence. The water-resistant wall-mount transmitter puts control in your hands: a Field Width adjustment knob widens or narrows the signal field so you set how far from the wire the receiver first activates, and two correction modes let you choose High Performance Pager vibration warning before stimulation or a pager vibration-only program. If a mower or a shovel ever nicks the wire, the Boundary Wire Continuity Light goes out and the transmitter sounds a warning beep — no silent failures. On the dog, the fully waterproof, ultra-compact receiver collar delivers 8 levels of adjustable correction matched to each dog's personality, with a battery life indicator and 2-hour rapid charge lithium-polymer batteries.

The In-Ground Fence for Big Properties and Determined Dogs

Wireless signals bounce off metal and shrink around buildings; a buried wire draws the exact same line every day, in any weather, around any shape of land. That consistency is what teaches a dog the boundary fastest — and it's why wired containment remains the professional choice for acreage, farms, and multi-zone layouts. Run the loop around 40 acres of pasture, carve out the flower beds, keep the dog off the septic field, or fence the front yard only — the E-FENCE 3500 follows your plan, not a preset circle. Add an EF-3500 Additional Receiver for each extra dog and every dog in the house works on the same boundary, each with its own correction level.

Frequently Asked Questions

How much land does the E-FENCE 3500 cover?
Up to 40 acres. The kit includes 500 feet of 20-gauge wire, and additional wire (sold separately) expands the loop up to the 40-acre maximum.

What happens if the buried wire gets cut?
The transmitter's Boundary Wire Continuity Light turns off and the transmitter makes a warning beep, so a disconnected wire never goes unnoticed.

Is the receiver collar waterproof?
Yes — the receiver/collar is fully waterproof and rechargeable, with a 2-hour rapid charge and a battery life indicator.

Can I run more than one dog on it?
Yes — add an EF-3500 Additional Receiver for each extra dog. Each receiver's correction level is set individually, so a mild dog and a stubborn dog can share one boundary.

What size dog is it for?
Dogs 15 lbs and up, from mild to stubborn dispositions, with 8 correction levels to match the individual dog.
