Product Description

Powerful enough to cover up to 100 Acres! Keeping your dog safe at home is a must for all dog owners. The SportDog Underground Electric Dog Fence can help.

Whether your dog hunts, trials or is a full-time companion, this Underground Dog Fence provides freedom and safety for $1,000's less than conventional fencing. Your dog wears a correction collar that receives a signal from the wire and warns him if he ventures too close to the perimeter. The waterproof collar receiver allows for four adjustable levels of correction plus a tone-only and vibrate-only mode. Safe and effective for dogs over 10 pounds.

The SportDog Underground Electric Dog Fence is easy to install and versatile enough to accommodate just about any yard or area. Installation is a simple as installing the wire around the perimeter and plugging in the transmitter.

Factory Grade Wire

This is the wire included in all self-install kits. Regardless of gauge, this wire is of medium quality, lighter weight and keeps shipping and initial costs down. This wire will work but does not hold up to the elements as well as a professional grade wire. The vinyl wire coating is prone to cracks and over time exposes the copper leaving the wire susceptible to damage. This can cause issues that impact the functionality of your dog fence system. Since finding, digging up, and repairing wire breaks can be a tedious job at best, many people prefer to upgrade to a pro-grade wire from the start.

heavy-duty-wire.jpgHeavy Duty Grade Wire

The initial cost of heavy duty grade wire is a bit more than manufacturer grade wire. However, there are many benefits to choosing heavy duty wire for your dog fence. Heavy Duty grade dog fence wire holds up better to freezing conditions, sunlight exposure, contraction and expansion of the ground, water exposure and general wear and tear. The long term savings in time and replacement if you are planning on staying in your home for at least a year or more, makes the heavier duty wire a much better investment.

  1. Works Great! 5 Star Review

    Posted by on May 24th 2016

    I really like the different options that the SportDog Dog Fence Transmitter offers! lt allows you to match the correction needed for individual dogs!
    The only con I have it the size of the collar. It's great for a large dog but it's to large for a smaller dog. Would be nice if you had an option on the actual collar size!

  2. Well made but lacking some features 4 Star Review

    Posted by on Jan 14th 2016

    I bought this to replace an Innotek fence that the Radio Fence company is no longer supporting, and whose rechargeable collars were only lasting about a year. This unit seems well made, and worked right out of the box. It is POWERFUL. At highest setting the fence projects a long way. The collar is very bulky (in contrast to the Innotek) but solid, and uses a standard 9v battery which is supposed to last 6 - 12 months -- we will see.

    The only issue I have with this system is that there are no available portable transmitters that can be placed at strategic places in the yard and home that we want the dogs to stay out of. The Innotek system had these, but they are not compatible, and we will have to buy different collars to use them, so the dogs would have two collars on. Crazy.

  3. Great Product and Service 5 Star Review

    Posted by on May 19th 2015

    The fence works perfectly along my 3 acres. (200 feet of the perimeter wire is submerged in a lake.) My transmitter has been victim to 2 lightning strikes. One was completely covered under warranty. The next, 5 long years later, was replaced by their Customer support team for under $50. I bought the lightning surge protector this time. I couldn't be happier.

  4. This dog fence covers so much space! 5 Star Review

    Posted by on Jun 16th 2013

    I have to say that this is a really great dog fence. Not only is it effective, but it covers so much space! We have a really big yard, so it was nice that this was able to cover the whole thing plus the front yard! I do not have to worry about my dogs with this. It has paid for itself already just with the peace of mind that comes with it. I am really happy with this fencing.

  5. WORKS GREAT!!!!!!!! 5 Star Review

    Posted by on Apr 15th 2013

    My wife and I installed it around 5 acres. It took about 4 hrs to get a game plan and set up. Once that was done, put collars on and started training. American bulldog set on 3 learned immediatly. The boxer knows its there but cannot grasp the boundry flags yet. But its been only 2 days. Great Product!!!

  6. saftey for my dog 5 Star Review

  7. Problem solved 4 Star Review

    Posted by on Jan 29th 2013

    Nice unit, I like the flexibility in controlling the boundary and static level for each dog. Male golden retriever and female boxer, golden went across 1 time and that was probably my fault. Since that time he's been introduced to the higher static level and now he stops 20 yds shy of the flags and just stares at them......what a beautiful sight! We put in a single 2500 foot loop, twisted section included and feel confident the unit will provide years of service. Overall, very pleased with the fence, it provides peace of mind.

  8. We have a border collie 5 Star Review

    Posted by on Jun 4th 2012

    Maybe just knowing the type of dog make you understand the "problems" you could face. She is a great do, and loves to run and herd anything that moves. I am worried she would run through the fence. She did, and each time we turned it up. Then, she acted like we were beating her and that was not what we wanted, but.... it took about 3 days and now she is great. We have had the fence for about 2 months now and it is working wonderfully. It allows us to leave her outside in the yard when we are away from home. I was having to lock her in a kennel every time we left, so that part we love. She respects the line and is doing great!

  9. it's a great item 4 Star Review

    Posted by on May 1st 2012

    We bought this fence for our 2 short haired German Pointers (now 1 year old), and our 4 1/2 year old lab, who has recently started running away, and worrying us, as there are fields with wildlife, and hunters! surrounding our property. It took only one training session for the lab, as he walked into the zone and got shocked! now he has a very healthy aversion to going anywhere near the flags!
    The pups are still in training, and I think it will take several more sessions, as they are quite headstrong, and will chase anything. Neither has had a 'real' shock yet, only a warning, but the sound, makes them turn away, so I am very hopeful it will work as well for them. It will be great for them to all safely run around the 1 1/2 acre property we have 'fenced' off.

  10. Very Short Training Time 5 Star Review

    Posted by on Apr 14th 2012

    Two 15 minute training sessions with our pit bull Blackjack, and he's VERY well trained to the invisible fence. This is for a dog who has never been restrained in a 20 acre area. Now he's quite happy with one acre and we have peace of mind.
    I have and will continue to recommend your fence to our friends.
