Underground Dog Fence®

Keeps your pet safe in your yard

The Guardian® Underground Dog Fence®  is a smart, affordable way to keep your pet secure in your yard. Set your pet’s boundaries by laying a wire around your yard, bury the wire just below the surface, and attach it to the transmitter. Your pet will wear a special receiver collar that works with the transmitter to keep your pet within the boundary. The collar will deliver a warning tone as your pet approaches the boundary followed by a quick correction if he attempts to leave the area. Train your pet in just 2 weeks!

Questions & Answers:

What is static correction?

Static correction is a mild electrical pulse, similar to the sensation you feel when you walk across carpet and touch a doorknob. It doesn't hurt but it is startling, and is a proven safe and effective behavior deterrent for pets. When first using the product, keep your pet on a leash. When he receives the correction, lead him back into the defined boundary, and reassure him with calm, gentle tones. He will regard the static correction as a deterrent.

Will this work for my yard?

The system includes 500 feet of wire, enough to enclose a square of up to 1/3-acre. You can create nearly any layout that will work best for you and your pet. We recommend you plan your layout and measure the length of wire you need, lay the wire out in your yard and test it with your transmitter. It may help to add 10-15 percent of wire length to your estimate to cover things like turning corners or twisting the wire to cancel the signal. See Operating and Training Guide for more tips.

What if I need more wire?

The Wire and Flags Expansion Kit PGA-500 includes 500 feet of burial grade wire compatible with your system, 50 training flags, and 2 gel-filled Capsules and wire splices. The accessory kit is available from Guardianpet.net

Will the system work if I have more than one dog?

You can use the system with as many dogs as you would like with your system as long as each pet wears a receiver collar. You can purchase an Extra Underground Fence® Receiver (GIG11-12113) for each additional pet.

My dog is wearing the collar. She hears the beep but continues to cross over the boundary line with no static correction. What should I do?

If the collar is too loose on your pet, she may not feel the correction. Adjust the collar so that it fits snugly; you should be able to fit a finger between the contact point and her skin. The contact points must touch the dog's skin.

I have a problem with my system. How do I know if the problem is the receiver, the transmitter, or the wire?

We recommend you perform our Short Loop Test. For more assistance, phone our Customer Care Center at 1-800-732-2677

Important Information

For the comfort and safety of your pet, check the fit of your pet's collar, the receiver collar batteries, and tightness of the contact point connected to the collar frequently. The Guide for this product describes proper collar maintenance. Just as humans can develop bed sores from remaining in one spot for too long, your pet can have a similar experience from prolonged wearing of a receiver collar. Do not allow your pet to wear the collar for more than 12 consecutive hours in a 24-hour period; this is for your pet's comfort. If any skin irritation is observed, discontinue the use of the collar for a few days. If the condition persists beyond 48 hours, see your veterinarian.
