"Back in the '80s we had Dog Guard Out of Sight Fencing come out and install the invisible fence around our one-acre yard. We are now on our third dog using the invisible fence and it still works like a charm. If we encountered an issue (rarely!), a quick phone call to Dog Guard took care of it. They are exceptionally responsive to making sure pets are kept safe. If they can't resolve the issue over the phone, they'll make a house call. No bothersome and unsightly chain link fencing! We have never regretted opting to go with Dog Guard Out of Sight Fencing. Totally worth every penny!"
Dink Suddaby

"Personal and professional from the first call to inquire. We are very pleased with our decision to try underground fencing for Sam. We were not sure how he would adjust to it since he had always been inside a chain link fence at our previous home. It has been a little over a month now and he is enjoying having more freedom, but surely respects his boundaries. I would highly recommend Dog Guard."
Tammy Syverson

"We rescued Malcolm about 2.5 years ago from an abusive situation. He's half Border Collie & Boxer. He runs like the wind chasing everything from leaves & squirrels to cars & skateboards. We had doubts whether this kind of product would work for dear Malcolm. Wow!! We're absolutely stunned, Malcolm is perfectly content to remain on the front porch! Dog Guard's training, service and responsiveness is what a customer desires. 5 stars... hands down!"

Frequently Asked Questions
Everything you need to know about Dog Guard
Dog Guard Out of Sight Fencing is an electric dog fence system that is installed underground by burying a single wire as a complete loop along the entire perimeter of your property. This underground boundary can also include certain portions of your yard, such as a pool or garden. Your dog is safely contained within your yard with the boundaries you are comfortable with.
First, a transmitter is installed in a convenient location, such as the garage or basement. Then, the wire loop is placed underground. The transmitter sends a harmless radio signal through the wire, which is picked up by the small receiver on the dog's collar. When the dog nears the wire, the receiver in the pet's collar picks up the signal and gives off the owner's choice of an audible warning or mild correction.
The correction has been thoroughly tested and proven to be harmless. It is a mild static pulsation, similar to a shock from a doorknob, yet unpleasant enough that the dog will quickly learn to avoid it. The whole purpose of a good pet containment system is to contain your pet without correcting him all the time. The Dog Guard system along with the training your pet receives ensures that your pet learns the boundary and stays away from it. Most pets will never sustain more than two or three corrections. Remember the level of correction must be greater than the level of distraction.
The boundary is marked off with flags, creating a visible boundary line for the pet. For two weeks, the dog owner should spend fifteen minutes, twice daily, exercising the dog around the flag boundary. If the dog moves toward the flags, he should be told "NO!" The dog should then be moved away from the flags and given lots of praise. By using this technique, the dog will quickly learn where the boundary is located. Later, once the dog becomes familiar with the visible boundary, the flags can be removed. Remember, praise and repetition are the keys to success!
Yes! Once your dog has completed training, he can be taken outside of the yard, BUT the Dog Guard receiver collar must be taken off before putting the leash on.
Our transmitter has three colored indicator lights. The red and green light should be on all the time, while the yellow light will only come on in the event of an electrical surge or lightning damage.
The Dog Guard brand dog fence system comes with a 30-day money-back guarantee. The transmitter offers a limited lifetime warranty against power surges and lightning strikes. The receiver is water resistant with a limited lifetime warranty. The DG 9 XT receiver is the most powerful receiver on the market, and our DG Micro Receiver is perfect for dogs 10 lb. and under, as well as cats! The transmitter is capable of enclosing up to 40 acres of property and is user friendly with indicator lights and range adjustment at your fingertips.
Everyone at Dog Guard, from the manufacturer to the dealers, has your pet's safety in mind. From the moment you purchase a Dog Guard pet containment system, you can rest assured that your dog is in good hands with our knowledgeable dealers and trainers and our skilled technicians. From equipment support when you have questions about your system, to moral support when you just don't know what to do with your pet, we will be with you every step of the way. If you love your dog and want to keep them safe and happy, Dog Guard is for you.
Dog Guard offers a complete package and not a do it yourself kit. We come to your house and install the system and help train you to train your pet. We offer a much more extensive warranty on the equipment than you will find at most retail stores. The wire we use in the installation of your system is "underground rated" and made to last when buried underground. Our equipment is flexible enough to contain the smallest and largest of pets without harming them. Our signals are "smart" so that pets are not corrected unnecessarily in areas of stray signals.
You want a system that is backed by a manufacturer that can be contacted whenever there is a problem. Some pets train quicker than others and some pets cannot be trained at all. In general, the amount of correction must be greater than the level of distraction. The correction is not harmful, but it must be effective enough so your pet learns to respect its boundaries.
We have a customer who has more than twenty-eight dogs on the system at one time, and they are contained in a three-acre area. The Dog Guard System is flexible enough to handle just about any number of pets in an area as large as 50 acres.
You have the option to purchase a battery backup similar to what a home computer might use. This product will give your system hours of additional time until the power is restored.
Dog Guard costs much less than traditional fencing, such as a vinyl fence, aluminum fence or chain link fence. More importantly, a Dog Guard pet containment system has none of the maintenance and aesthetic problems. The final cost can vary, depending on the size of the property and the number of dogs on the system. However, we work directly with the manufacturer, so there are no middleman costs, and the cost of your Dog Guard system may be lower than you think.
Dog Guard systems can cover up to 40 acres so it is great for farms and those living in rural areas.
Our interior wireless transmitter units that work with the same collar as outside fence are perfect for keeping pets away from areas inside of your house like doorways, staircases, and countertops.
Puppies are ready to be trained at approximately 14-16 weeks old, depending upon the breed. When the dog knows simple commands like "no" and can walk fairly well on a leash then the dog is mature enough to begin training on a Dog Guard system.
