Underground Dog Fence Kit for Reliable Dog Containment

Give your dog a defined outdoor boundary with this underground dog fence kit, a wired pet containment system designed for homeowners who want to create a customizable boundary around their yard without installing a traditional physical fence. The system combines a wall-mounted transmitter, receiver collars, boundary wire, training flags and installation accessories to create an invisible perimeter for your dog.

With adjustable boundary control, support for multiple collars and a coverage area of up to approximately 1.2 acres, this underground dog fence kit is designed for a variety of residential yards and outdoor spaces.

Why Choose This Underground Dog Fence Kit?

Traditional fencing can be expensive, time-consuming to install and visually intrusive. An in-ground dog fence provides another way to define where your dog should remain while keeping the boundary discreet.

This underground dog fence kit uses a buried boundary wire connected to the transmitter. When the receiver collar approaches the configured boundary, it provides an audible warning followed by adjustable stimulation according to the selected setting.

The boundary width can be adjusted using the transmitter, allowing you to customize the containment area to suit your property.

Major pet-containment brands such as PetSafe, Dogtra and SportDOG also use the same basic wired containment concept: a transmitter sends a signal through an underground boundary wire, while a receiver collar detects the boundary and provides warning and correction cues.

Customizable Underground Dog Fence System

One of the biggest advantages of an underground system is the ability to create a boundary that follows the shape of your property.

Unlike a wireless circular fence, the boundary wire can be arranged around the areas where you want your dog to stay. This makes an underground dog fence kit suitable for many different yard layouts.

The included system supports an adjustable control range of up to approximately 5,000 square meters / 53,189 square feet / 1.2 acres, depending on installation conditions and boundary configuration.

The system also includes a wire-break warning feature to help identify a broken or disconnected boundary wire.

2 Receiver Collars for Multiple Dogs

This package includes two adjustable receiver collars, making it a practical option for households with two dogs.

The collars are designed for dogs weighing approximately 4 lb and above, with adjustable neck sizing from approximately 7.5 to 17.92 inches.

The transmitter can support up to three receiver collars according to the supplied product specifications, while this package includes two collars.

Each dog can therefore have its own receiver while sharing the same configured boundary.

300m Boundary Wire for Flexible Installation

The system is available with a long boundary-wire configuration designed for larger outdoor areas.

The 300m dog fence wire option provides approximately 984 feet of boundary cable, giving you flexibility when planning the perimeter around your property.

The wire can be installed underground according to the recommended installation method. The supplied training flags help you create visible boundary markers while your dog learns where the containment area begins.

For best results, carefully plan the complete wire loop before installation and make sure the boundary wire is properly connected to the transmitter.

How the Underground Dog Fence Kit Works

The system operates through three main components:

1. Wall-Mounted Transmitter

The transmitter acts as the central controller. The boundary wire must form a complete loop connected to the transmitter so the system can generate the containment signal.

2. Receiver Collar

Your dog wears the receiver collar around the neck. As the collar approaches the boundary, it provides an audible warning and, depending on the configured setting, stimulation if the dog continues toward the boundary.

3. Boundary Wire

The wire defines the containment area. It can be installed around the perimeter of the yard to create an invisible boundary without constructing a conventional fence.

DIY Installation

This underground dog fence kit is designed as a DIY installation project.

Before installation, determine the area you want your dog to access and calculate the amount of boundary wire required.

The general installation process is:

• Design your containment area.
• Calculate the required wire length.
• Install the wall-mounted transmitter.
• Lay the boundary wire around the planned perimeter.
• Connect the wire loop to the transmitter.
• Check that the transmitter is functioning correctly.
• Configure the receiver collars.
• Test the containment system.
• Adjust the boundary width.
• Install the training flags.
• Fit the collars correctly.
• Begin gradual boundary training.

The supplied instructions should always be followed before operating the system.

Adjustable Boundary Control

Different properties require different boundary widths. This electric dog fence system allows you to adjust the signal range using the transmitter control.

The receiver can detect the boundary signal at a distance from the wire depending on the selected field-width setting. The supplied specifications indicate an approximate detection range of around 1 meter at the minimum setting and around 2 meters at the maximum setting.

For smaller dogs or smaller yards, use an appropriate lower field-width setting and test the system before beginning training.

Dog Fence Collar for Small, Medium and Large Dogs

The receiver collars are designed for dogs weighing 4 lb or more and feature adjustable straps.

Short contact probes are recommended for short-haired dogs, while longer contact points can be used for dogs with longer coats.

Always ensure the collar is correctly fitted and follow the manufacturer’s instructions before beginning use.

The receiver uses a 4LR44 6V battery. The supplied specifications indicate an expected runtime of approximately 10 days per battery, depending on use.

What Is Included?

The package includes the main components required to create your containment system:

• 1 × indoor wall-mounted transmitter
• 2 × adjustable receiver collars with straps
• Power adapter and charging cable
• Receiver batteries according to the supplied configuration
• Boundary wire
• 20 × training flags
• 2 × test bulbs
• Extra metal contact points
• Screws and installation accessories
• User manual

The exact wire option should be selected according to your property’s layout and the available product variation.

Important Training & Usage Information

An electronic containment system should be introduced gradually. Allow your dog to become familiar with the collar before starting boundary training.

Training flags are useful during the initial learning period because they provide a visible reference for the invisible boundary.

Always supervise your dog during training and monitor how your dog responds to the system. Do not leave the receiver collar on your dog for more than the recommended daily duration. The supplied product instructions specifically recommend not keeping the collar on for more than 12 hours per day.

This product is intended for dogs only. Keep the transmitter and accessories away from children and carefully read the user instructions before installation and use.

Is an Underground Dog Fence Better Than a Wireless Dog Fence?

It depends on your property.

A wired system is useful when you want to create a customized boundary that follows the shape of your yard. Wireless systems generally create a circular boundary around a transmitter and can be faster to install.

PetSafe explains that wired systems offer customizable boundaries, while wireless systems are easier to install and portable.

If you need a defined perimeter around a house, garden or irregular outdoor area, an underground dog fence kit can provide more flexibility than a simple circular wireless system.
