Dogtra E-Fence 3500 (EF-3500) - Electronic Dog Containment Fence System

Dogtra E-Fence 3500 (EF-3500) - Electronic Containment Fence

An advanced electronic fence system that lets you set custom boundaries around your home and yard - so your dog enjoys full freedom in the space while you enjoy the peace of mind of knowing it can't escape. An ideal solution for private yards, homes without a physical fence, or as a complement to an existing fence.

How It Works

A boundary wire is laid around the area you define and connected to the base transmitter, and the dog wears a light, waterproof receiver collar. As the dog approaches the boundary, the collar first issues a pre-warning (tone/vibration), and only if the dog keeps advancing does it deliver a controlled-intensity stimulation. This way the dog quickly learns where the boundary is and stays in the safe zone.

Key Benefits

• Warning before stimulation - a pre-alert (vibration/tone) that gives the dog a chance to turn back before any stimulation.
• Vibration-only mode - an option to operate and train with no electrical stimulation at all.
• 8 intensity levels - precise tuning for every dog, from sensitive to independent.
• Low-to-medium output - mild, controlled stimulation, designed for humane training, not punishment.
• IPX9K waterproof collar - fully water-resistant to rain and bathing.
• Includes 1200 m of wire - suitable for small yards up to very large areas.
• Wire-break alert - indicator light and warning tone if the boundary wire is damaged.
• Advanced filtering system - signal stability and prevention of interference and false alerts.
• Expandable - add more receiver collars for several dogs on the same system.
• Fast-charging Li-Po batteries - full charge in about 2 hours.
• Suitable for dogs from 7 kg - a solution for small dogs too.

Who Is It For?

Owners who want to give their dog freedom in the yard safely, homes without a fence or with an inadequate fence, and trainers looking for a reliable, durable, precise containment tool. Suitable for a range of sizes and breeds.

Responsible Use

The system is based on pre-warning and gradual learning - not punishment. We recommend a short introduction period in which the dog learns the boundaries with flag markers and positive reinforcement. For level tuning and professional guidance, we're happy to help.
