We developed our Flexpetz exclusive eXtreme™ Dog Fence Wire to meet our customer's needs for a heavy duty dog fence wire with a superior coating protecting the copper within. No matter how thick your dog fence wire, it's only as good as the jacket that protects the copper from moisture and other damaging factors like rocks, tree roots, and rodents. 

Our eXtreme™Dog Fence Wire has a triple polyethylene coating that is both UV and waterproof and 3 times as thick as our professional-grade heavy duty wire. 

This 500 ft. boundary expansion kit includes everything you'll need to expand your dog fence system by about 1/3 acre. We've pre-bundled just the right number of flags and splices for the 500 ft. of wire so you can conveniently increase the size of your dog fence in one quick click. 

  • 14-Gauge eXtreme™ Wire
  • 60mil Polyethylene Jacket
  • Waterproof & UV Proof
  • Compatible With All Dog Fence Systems


Kit Includes:

  • 500 ft. eXtreme™ 14-Gauge Wire
  • 50 Training Flags
  • 2 Waterproof Wire Splices

New installation kit
Just recently moved and wanted to bring my fencing system along with me. Called the people at FlexPetz to see how hard it was going to be to bring all the equipment and wire with me and they were able to help me find this product.

I decided to leave the old wire and just bring my electronics with me. So I purchased this kit which had everything I needed to install my system at my new place and it even comes with the boundary flags so that my dog is aware of her new boundary. Very happy with the quality of wire in this kit too, my last wire was very cheap in comparison.

After this new wire was laid out and installed, I had my fence working within 30 minutes soon after. Transmitter just gets mounted and plugs back in and I have a fence. Really a D.I.Y. project made easy and saved me hundreds of dollars. Thanks FlexPetz.

Needed a new wire kit for my previous system.
Recently had to move to FL and wanted to bring my fencing system with me. Got a nice 1/4 acre lot and was happy to find this package had everything I needed to get the wire installed. Got my wire and boundary flags for my dog. He loves the weather here and I am glad this was available to use. Now that he has an established boundary he is free to play all day.

Great addition to my system.
So glad I found this product. Needed better wire so that my fence system didn't break all the time and found this. I had lost my dog twice before I found out why my fence wasn't working. After realizing that my wire was junk, I purchased this.

I am extremely pleased with this package. They included everything I needed to change my wire for my old system. It was really easy to do, especially with the help from FlexPetz techs and their videos. I do not see me having to replace this wire anytime soon because it is super durable. Thanks again FlexPetz for this amazing product.

Excellent dog fence wire!!!
After owning an invisible fence for 10 years and constantly looking for wire breaks I finally broke down and purchased this extreme wire. Extreme is the correct name as there is absolutely a noticeable difference from what I pulled out of the ground and this product. My only regret is not measuring well enough as I ended up having to buy another spool and would rather have just used one continuous roll. Review by Dave (Posted on 4/21/2014)
