How much dog fence wire do I need?



We call it 'Overkill Wire' for a reason. This 12-gauge wire is the thickest dog fence wire available. Recommended for those who like to 'over do' it and also for installations where lawn care equipment is in heavy use. 

Use the chart on the left to determine how much dog fence wire you need based on your installation size, rounding up rather than down to account for twisted segments and possible mistakes or splicing. Then add as many boundary extension kits as needed for your planned installation. 

Our boundary wire kits are the most convenient way to expand your dog fence because we've already calculated and included the proper number of training flags and splices based on the linear feet of wire. 

Kit Includes:

  • 500 ft. 12-Gauge Wire
  • 50 Boundary Flags
  • 2 Waterproof Wire Splices
  1. Excellent Review by Fors

    We bought this 3 years ago after moving to our new house. My girlfriend had 2 labs and we needed wire for the invisible fence brand unit and didn't want the expensive Invisible Fence Brand wire. This is VERY sturdy and was VERY EASY to work with. I don't know why someone said it was "harder to work with" but it's not at all!! My girlfriend and I both ran the lines and buried it about 4" deep. She kept saying it would be easy, but I had never worked with anything like this before. She was right! It was very easy! Took us less than an hour to run and hook up the 1000 foot perimeter. She said the price was very reasonable for the gauge compared to the invisible fence brand. (Posted on 2/5/2017)

  2. Perfect for my needs Review by Overkill Style

    Like the description said it is harder to work with but I wanted to be once and done. Definitely worth the extra effort. (Posted on 4/9/2013)
