Major Credit cards
Dog with Hyper collar

The eXtreme Dog Fence Pro System includes everything you need to setup your inground dog fence, train your dog, and ensure that your dog stays safely contained in the perimeter you set.

The transmitter is feature rich. It can accommodate up to 25 full acres, and gives you the option to change the radio frequency the system functions on (to avoid interference with any neighboring electric dog fence).

This Hyper fence kit provides stronger correction levels than does the “Active” (AVERAGE DOG) system. This system is packaged with value and longevity in mind for your large / bull headed dog(s).

The collar is not only waterproof, but submersible to 10 feet.

eXtreme Dog Fence Transmitter

Digital Transmitter

Dimensions: 4.5″ high x 5.5″ wide x 1″ deep

The fence transmitter is the brain of your eXtreme Dog Fence. You not only set your signal field width here (which is the distance from the wire that the collar will activate), but you also program your collar’s correction level here.

You can also change AM radio frequencies here, if you have a neighboring fence system that is causing interference with your fence.

The transmitter should be mounted indoors, so as to avoid any moisture getting into the electronics, and at least 3′ away from any large metal objects.

Hyper Collar

Waterproof “Hyper” Collar

Receiver Dimensions: 1.4″ high x 1.5″ wide x 2″long

Strap Dimensions: 3/4″ wide (fits necks from 10″ to 30″)

Contact Probe Dimensions: small = 5/8″, large = 7/8″

The “Hyper” collar is waterproof and submersible to 10 feet, with no impact on the receiver’s performance.

It includes a long set of contact probes for dogs with long neck hair, and a short set for dogs with shorter hair. A set of metal infused rubber comfort covers are included to help keep the contact probes comfortable on your dog’s neck.

The receiver weighs a mere 1.4 ounce and runs on a proprietary 7.5v battery, which lasts an average of 4 months (after the battery used during the training period).

The collar receiver has 7 correction levels (1-7) and a beep only level (0), to accommodate a wide range of dog sizes, breeds, personalities and temperaments.

Dog Fence Boundary Wire

Specs: Heavy Duty Dog Fence Wire

The boundary wire included in the eXtreme Dog Fence is a thick solid heavy duty wire. It’s generously coated in a light but rugged polyethylene jacket, which is direct ground burial rated, UV resistant, and designed to perform for years and years out in the elements.

The standard D.I.Y. electric dog fence is typically packaged with a thin 20 gauge wire, from the manufacturer. The coating is an inferior PVC jacket, which provides minimal protection and tends to degrade prematurely. This creates frustration when the customer has to try and dig up this degraded wire to repair or replace.

With eXtreme Dog Fence Pro-Grade, you can be assured that your boundary wire will last and perform for the life of your beloved dog, keeping him or her safely contained in the perimeter you set.

How to program your correction level


Temp Check

Temp Check™

Keeps the fence field stable and in the same location when outside temperatures change. Boundaries that randomly and unexpectedly move are frustrating and dangerous for your pet.

Frequency Encoding

Frequency Encoding

Eliminates stray signal interference from neighboring dog fence systems and other signal generating devices. Nearby dog fence systems and other devices that generate similar signals can interfere with your electric dog fence causing signal interruption or unreliability.

Wire Check

Wire Check™

Automatically compensates for wire problems and adjusts the amount of signal power to ensure the fence boundary remains in a constant location.

Battery Check

12x Battery Check™

Monitors the status of the training collar battery every two hours, eliminating false low battery indications saving you both time and money.

Questions & Answers

Question: I have 1 acre of land. How much wire do I need?

Answer: You would need to order 1,000 feet of wire with your kit, since the wire comes in 500 ft. increments. Regarding a more specific number you will end up using, you would need to take into consideration the shape of the boundary. For example, if the boundary is shaped in a square, you would need approximately 836 feet total.

Question: What batteries does the collar use?

Answer: The active collar (red strap and blue receiver) runs on Perimeter 6-volt batteries. Our stubborn dog collar (solid blue) runs on 7.5 volt collar batteries.

Question: Does it alert you if your dog gets out?

Answer: No, there is no alarm or notification at the transmitter if the dog gets out of the boundary.

Question: Can additional collars be added in the future for other dogs?

Answer: Absolutely! An unlimited number of dogs can be contained on this system.

Question: Do I need to be an electrician to install this fence?

Answer: No you don’t need to be an electrician. Hooking up your dog fence is quite simple, and doesn’t require any special skills to complete. All you need to be able to do is hook up 2 wires to 2 screws on the transmitter.

Question: Will the entire dog fence work if there is a break anywhere in the wire?

Answer: No it won’t. If there is even the smallest break in your dog fence wire, your entire fence is compromised, and an alarm will sound at the transmitter. This alarm means that if your dog is out in your yard, he is not protected and can get out of the fence. This is why choosing the right dog fence wire in the first place is so important.

Question: Can I run the wire above the ground, along a fence for example?

Answer: Yes, you absolutely can. However, it is highly recommended if doing this that you go with a Pro Grade or Max Grade kit that comes with a thick and sturdy cable to protect it from a potential wire break.

Question: Will a yard that has a lot of trees disrupt the dog fence signal?

Answer: Absolutely not. No amount of trees will interfere with the signal coming off of our eXtreme Dog Fence Wire.

Question: How many collars come with the kit and can I order extras?

Answer: One collar comes with your kit. You can add as many collars as you need by using the dropdown menu to do so.

Question: Do you have a remote trainer that works with your dog fence?

Answer: Yes, we sell a remote trainer, but it doesn’t use the same collar as your dog fence does. However, what you can do is remove the receiver from the remote trainer collar and slide it onto your dog fence collar, so that both receivers are on the one collar.

Question: Is there a vibration feature as well as a tone and a shock?

Answer: No, there is no vibrate feature on the eXtreme Dog Fence.

Question: Can I just wait until the spring to bury the wire? Will the wire be okay if there is snow on top of it?

Answer: Our Prograde and Max grade wire definitely sturdy enough to weather the elements. You can certainly wait until the spring to bury your dog fence wire.

Question: Does the transmitter need to be mounted in a temperature-controlled environment?

Answer: No it doesn’t. High or low temperatures are not an issue; however your dog fence transmitter can absolutely NOT get wet.

Question: How old does my dog need to be to use the eXtreme Dog Fence?

Answer: As young as 6 months old is fine. The important thing is that the dog needs to be able to understand basic commands.

Question: Can the transmitter be plugged into an outdoor porch?

Answer: Yes it can. However since it must be protected from moisture, it should be kept in a waterproof box, such as a sprinkler box.

Question: What is the twisted wire used for?

Answer: Twisted wire is used to connect the boundary loop to the transmitter. When used in this way, twisted wire is neutral and won’t correct your dog for crossing over it. However, twisted wire can never be used as part of your boundary loop itself.

Question: Does the dog fence wire need to be ran in one continuous loop? Can it just be ran on one side of the property?

Answer: Yes, as with any dog fence, your dog fence wire must be ran in one continuous loop. Yes it can be ran just on one side of the property, but a double loop must be created there, with 4 feet separating its parallel sides.

Question: Will the collars still shock with the rubber contact points covering the tips?

Answer: Yes, they will. The rubber contact points are metal-infused, so they are still able to deliver the static correction through them.

Question: How deep should I bury the dog fence wire?

Answer: 3-6 inches is recommended.

Question: In a double loop installation, can I put both loops together in the same trench?

Answer: No you can’t. The parallel wires must be separated by 4 feet, which means they must be buried in 2 separate trenches.
