Extra dog fence wire is easy to shop for because you don't have to purchase a specific brand. Any brand of underground dog fence wire (including generic brands) will work with any brand of in-ground dog fence you own.
We carry a broad selection dog fence boundary wire for you to choose from including 20-gauge, 18-gauge and Ultra Wire by High Tech Pet. Ultra Wire is 40% thicker and about three times stronger than the thinner 20-gauge dog fence wire that comes standard with many dog fence systems.
We carry generic dog fence wire as well as boundary wire supplied by pet fence brands such as PetSafe, Innotek, High Tech Pet, Dogtra, DogTek, and SportDOG.
