The best, most advanced dog fence on the market today.

Keeping your dog safe at home is a must for all dog owners. SportDOG Brand can help. Whether your dog hunts, trails or is a full-time companion, our containment system provides freedom and safety for $1,000's less than conventional fencing. Our in-ground fencing is easy to install and versatile enough to accommodate just about any yard or area. More than one dog to contain? No problem, simply purchase additional collars. Like all SportDOG products, our containment system and components are backed by a Lifetime Limited Warranty.

Safe and effective for all dogs over 10 pounds, the SportDOG Brand In-Ground Fence System can cover up to 100 acres. (This system is for 1 acre) Installation is a simple as installing the wire around the perimeter and plugging in the transmitter with the included adapter. Your dog wears a collar that receives a signal from the wire if he ventures too close to the perimeter. Follow the included training instructions to get your dog used to his new boundaries and your dog will be staying safe at home in no time.

You can contain an unlimited number of dogs on your fence as long as each of them has a receiver.

How The SportDOG Fence Works

The Transmitter plugs into a standard outlet and emits a radio signal that travels along an underground wire. You can adjust the signal to up to 15 feet from the wire. In most cases, a 4-6 foot signal field will be the best for optimal training. The lightweight receiver worn on your pet's collar picks up the radio signal and alerts him as he nears the underground boundary that you have customized for your yard. When he approaches the boundary, he receives a warning beep. If your dog does not return, he receives a static correction which is startling but not harmful. Our maintenance free design and ease of installation offers tremendous savings compared to conventional fencing and other systems of this type.

SportDOG makes it easy to train your pet. By spending just 15 minutes a day working with your pet, he can be fully trained in a few days. You can train as many dogs as you want on the same system, as long as they are each wearing a receiver collar. Additional receivers are available if your have more than one dog.

SportDOG offers the flexibility you need to solve your installation needs. Bury the boundary wire underground approximately 1-2 inches deep. Using your own design, you can protect your flower and seedbeds, shrubs, trees and even swimming pools.


 Exclusive Features

  • Ideal for any size yard, even up to 100 acres
  • 100% Waterproof Collar-receiver provides four adjustable correction levels plus beep and vibrate-only modes.
  • One collar-receiver included. System expands to include any number of dogs with purchase of additional collar-receivers (Model SDF-R).
  • Low-battery indicator.
  • Receiver uses a common 9 volt battery with an average life of 6-9 months.
  • Built-in lightning protection.
  • 1,000 feet of wire and 100 boundary flags.
  • Wire-break alarm on transmitter.
  •  "Anti-linger" feature on collar keeps dog from constantly testing boundary.  

 This system is for ONE dog and for yards up to 1 acre. (Add additional collars at time of purchase)

Initial system set up and pet training will create more drain on the batteries than normal. Typically the batteries included with the receiver will need to be replaced after 30-60 days. Battery life under normal usage averages 6-9 months. The SportDOG Receiver uses a common 9-volt battery.
