Dogtra E-Fence 3500 (EF-3500) – In-Ground Dog Containment System

Dogtra E-Fence 3500 (EF-3500) – In-Ground Dog Containment System

The Dogtra E-Fence 3500 is an advanced electronic containment system that lets you define custom boundaries around your home and yard — so your dog gets full freedom of movement on the property, and you get the peace of mind that they're safe and won't run off. An ideal solution for private yards, homes without a physical fence, or as a supplement to an existing fence.

How does it work?

A boundary wire is laid around the area you define and connected to the base transmitter, and your dog wears a light, waterproof receiver collar. As the dog approaches the boundary, the collar first triggers a pre-warning (tone/vibration), and only if the dog keeps advancing is a controlled-intensity correction applied. Dogs learn quickly where the boundary runs and stay inside the safe zone.

Key advantages

• Warning before correction – vibration/tone gives your dog the chance to turn back before any stimulation.
• Vibration-only mode – train and operate with no static stimulation at all.
• 8 intensity levels – precise adjustment for every dog, from sensitive breeds to independent ones.
• Low to medium output – moderate, controlled stimulation designed for humane training rather than punishment.
• IPX9K waterproof collar – fully resistant to water, rain and bathing.
• Includes 3,900 ft of wire – suits small yards through very large properties.
• Wire break alert – indicator light and warning tone if the boundary wire is damaged.
• Advanced filtering system – signal stability, preventing interference and false alerts.
• Expandable – add more receiver collars for multiple dogs on the same system.
• Li-Po fast charging – full charge in about 2 hours.
• Suits dogs from 15 lbs – a solution for smaller dogs too.

Correct and responsible use

Consult a professional familiar with the product before starting work. The system is built on pre-warning and gradual learning — not punishment. We recommend a short introductory period in which you teach your dog the boundaries using marker flags alongside positive reinforcement.
