At first glance, it may seem that Dogtra GPS Fence is a newer version of Dogtra EF-3500 and fully replaces traditional wired systems. In practice, this is not the case.

Dogtra GPS Fence and Dogtra EF-3500 are two different types of electronic dog fence, designed for different conditions and different tasks. They are not direct competitors. Each technology has its own advantages and works best in specific situations.

The right choice depends not on which system is newer, but on the size of your property, the layout of the area and the zones you need to restrict for your dog.

How electronic dog fences work

Dogtra GPS Fence — wireless GPS dog fence

Dogtra GPS Fence is a wireless GPS electronic dog fence that allows you to create a virtual boundary without laying a cable. The system uses GPS navigation, and all settings are managed through a mobile app.

• no boundary wire required;
• control through a mobile app;
• multiple areas can be saved;
• suitable for large open properties;
• convenient for home, country houses, farms and travel.

Through the app, you can create virtual boundaries, adjust warning and correction zones, save different properties and quickly change the size of the area when needed.

The main advantage of a GPS dog fence is mobility. One system can be used at home, at a summer house, on a farm, at a country property or while travelling. No installation, digging or repeated wire placement is required.

Dogtra EF-3500 — wired electronic dog fence

Dogtra EF-3500 is a wired electronic dog fence that uses a stationary transmitter and a special antenna wire. This system is designed for permanent installation where high boundary accuracy is required.

• high boundary accuracy;
• internal restricted zones can be created;
• suitable for complex property layouts;
• a good option for permanent installation;
• useful for restricting flower beds, gardens, pools or vegetable areas.

The wire is laid around the property and forms a signal boundary. It does not carry electrical current to affect the dog; it works as an antenna. When the dog approaches the wire, the collar first gives a warning signal and then, if necessary, applies correction.

Accuracy of GPS and wired electronic dog fences

The main difference between the two technologies is how the boundary is created. Dogtra GPS Fence creates an outer virtual perimeter using GPS. Its accuracy depends on satellite signal quality, terrain, tree density and nearby buildings.

That is why GPS Fence works best on large open properties, where small coordinate deviations do not interfere with normal system operation. Wider warning zones help the dog understand in advance that it is approaching the boundary and calmly change direction.

Dogtra EF-3500 works differently. The boundary is defined by the position of the antenna wire, so the system provides much higher accuracy. This is especially important on smaller properties or near objects that the dog should not approach.
