I attached 3/4 of the original wire to my wire fence, and the rest went in the ground. Within a month, the part attached to the wire had failed, something keeps biting through it, don't know if it's the smell or the color, yellow or orange, but something likes it. I splice and tape it together. Not my dog she would get zapped. I ordered this and it is a very sturdy black, wire. When the original underground part fails, which I'm sure it will, I will replace it with the Extreme Dog Fence Wire. ## Features - 500 Feet of eXtreme Dog Fence High Performance 16 Gauge Electric Dog Fence Wire - Polyethylene Coated - Stronger and Longer Lasting than Any 20 or 18 Gauge Underground Dog FenceWire - Boundary Wire Protected by a Rugged Polyethylene Jacket to Protect from UV Rays, eXtreme Temperatures, and Water - Compatible with All Dog Fence Systems / All Brands (See List Below) / Universal - Manufactured in the United States using Imported Parts - See our desertcart store for more pet fence accessories and related items ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07D2JPD5P | | ASIN | B07D2JPD5P | | Best Sellers Rank | #101,457 in Pet Supplies ( See Top 100 in Pet Supplies ) #256 in Dog Wireless Fences | | Brand Name | Extreme Dog Fence | | Customer Reviews | 4.6 4.6 out of 5 stars (59) | | Date First Available | May 14, 2018 | | Date First Available | May 14, 2018 | | Is Discontinued By Manufacturer | No | | Item Package Dimensions L x W x H | 6.85 x 6.77 x 6.14 inches | | Item Weight | 0.01 Ounces | | Manufacturer | Extreme Dog Fence | | Manufacturer | Extreme Dog Fence | | Material | Polyvinyl Chloride | | Package Dimensions | 6.85 x 6.77 x 6.14 inches; 0.01 ounces | | Size | 16 Gauge - High Performance | | Target Audience Keyword | dogs | ## Images ![16 Gauge Electric Dog Fence Wire, 500 ft, Underground Boundary Wire | 500-ft continuous spool; polyethylene jacket, UV-resistant, direct-burial; fits Extreme Dog Fence, PetSafe & all in-ground - Image 1](https://m.media-amazon.com/images/I/51e2gx54Q5L.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works like advertised *by S***T on December 13, 2025* Came as described ### ⭐⭐⭐⭐⭐ Does The Job *by J***N on August 28, 2023* Sooo much heavier a wire than what came with the underground system.
