DogTek Electronic Dog Fence – EF-4000


We all want what is best for our pets, and giving them freedom to be outdoors off leash is something they all enjoy.  It is not always easy with above-ground, unsightly containment fence, as many of us live in communities where fence is not permitted or we just don’t have the time and money for construction.  DogTek has introduced the EF-4000 Electronic Dog Fence which is an affordable alternative to containment fence and other invisible fence systems.

The EF-4000 from DogTek is an invisible dog fence which enables you to keep one or more dogs safe in complete freedom within a perimeter that you define without the need of an ugly containment fence. You will be able to rest assured that an unlimited number of receiver collars can be used within one perimeter to contain as many dogs as you wish safely in the same area.  The EF-4000 comes with one receiver collar, and additional receiver collars are sold separately so that you can add more dogs.

The advanced technology in the EF-4000 DogTek Electronic Dog Fence System makes it adaptable to any type of terrain: open, wooded, hilly, fenced, unfenced, hot or cold!  If you have existing boundary fence, you can install the EF-4000 on the existing fence, or it can be easily placed under the ground.  Installation is relatively easy compared to typical fence systems.

How the DogTek EF-4000 Electronic Dog Fence System Works

A discrete, state-of-the-art perimeter wire (up to 450 yards) is easily placed under the ground or raised on an existing fence. This wire carries a signal from the small, mountable transmitting device. Your dog wears the adjustable, high tech receiving collar that communicates with the perimeter wire. When your dog first approaches the wire he will enter a buffer area called the “warning zone” (which is set by you on the control panel). If the dog gets too close to the perimeter wire, he will get alerted by a beep from the collar. As your dog gets closer to the wire within the warning zone, he will enter a correction zone. Once entering this zone, he will be corrected by a small, safe, and humane electronic stimulus. As your dog leaves the designated correction zone, the impulses from the collar stop.

DogTek Transmitter for EF-4000 Electronic Dog Fence

You have full control over every aspect of the DogTek EF-4000 electronic dog fence. You can set one of 8 levels of intensity on the dog collar. This will ensure the impulses won’t be insufficient for the larger breeds. Exclusively with the DogTek EF-4000, you now can independently adjust each of the boundary lines separately via a state-of-the-art control panel. Adjust the sizes of the warning and correction zones!

Top of the line collars, waterproof constructed receiving collars from DogTek produce a clear and recognizable tone that has been tested and proven effective in reinforcing the electric stimulus. The EF-4000 collar automatically increases the pulsating rate of the tone in the warning zone as your dog approaches the correction zone. This will expedite the training process so that your dog will learn exactly where the invisible boundaries are, wherever you decide to set them.
