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.

Cut Your Pet Fence Installation Time in HALF & Avoid The Task of Burying Wire. Use Our "Pet Fence Staples" to Install Your Underground Fence - Above Ground! Learn About Above Ground Pet Fence Installation.

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. 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.

  2. This is a great unit and a great buy 5 Star Review

    Posted by on Mar 26th 2012

    "I have two Large Golden Retrievers dogs and they are keep in the yard with this unit. The batteries last about 7 months and to change the all it takes is a 9 volt batteries to replace. And you can set any type of setting to fit you dog.

  3. This is an excellent dog fence at a great price 5 Star Review

    Easy to use Easy to install

  4. 1 Acre Underground Fence 5 Star Review

    Posted by on Feb 3rd 2012

    We have our 1/3 of an acre yard fenced with this. It was easy to intall, easy to move and best of all out dog stays inside the boundary! It took 1 day of training and one shock. So far so good. We live across from a large park with lots of squirrels and dogs going by all day long. In the past he has climbed, dug, jumped etc. We also have a spotdog radio collar for when our dog is off leash; this was also a great product. Good job Sport Dog for making an affordable and workable unit for out escape artist!

  6. Happy Customer 5 Star Review

    Posted by on Jan 23rd 2012

    We've been really happy with our SportDog Fence. We contain two active and large dogs (lab and husky). Installation was well-documented and easy. Our lab caught on within the first day or two. The husky was a slightly bigger challenge, but she had it down after about 10 days and a higher ""correction"" level. This has been great for us since there are a lot of off-property enticements in our rural area. The dogs still chase wildlife, but stay on our property.

    We did the installation in a few hours. Before doing anything, my wife and I walked-off the perimeter with a 100ft rope to gauge use of the 1000ft of wire. We used the staples which also made it easier. Definitely read the instructions before beginning and plan out your area.

  7. it works 4 Star Review

    Posted by on Jan 5th 2012

    To plug the main wire into the side of the unit the cover had to be removed.It felt like the hole in the plastic side of the control panel was not made large enough.

  8. It Works! 4 Star Review

    Posted by on Dec 22nd 2011

    We have 2 Dalmatians and a Black Lab/Pit Bull mix on 10.5 acres , with a pond. I made a circle that is 2500' feet long....this system works very well...my dogs are very active...they swim every day- this does not bother the waterproof collar. They don't just swim with the collars on - they attack (play) each other constantly...in the pond, on land, every day, all day! It only took about 1 week to train them, even with such a large area as I have. They do not challenge the collar, even though it is on it's lowest shock setting. This system is impressive, and my wife and I agree it was money very well spent!

  9. We now have three systems. 5 Star Review

    Posted by on Dec 20th 2011

    I bought my Sport Dog in ground fence about 3 years ago to use with my 1 year old boxer (Astro). It was awesome. It was easy to train and we were so impressed that my dad and my father in law both bought the same system for their property. We have quickly taught all three dogs the boundary at all three houses. Now I am going to buy a extra collar for my son in law's lab.

  10. Second time buyer 5 Star Review

    Posted by on Dec 19th 2011

    My son has the same fencing at his home and when the dogs visit each other they are safe either place
