Dog Fence Calculator Questions
How much boundary wire do I need for a dog fence?
Add your boundary loop, double the transmitter run (both twisted strands count), double each driveway crossing, then add about 10% for splices and repairs. The wire calculator does this and rounds up to 500 ft rolls.
How much does a DIY underground dog fence cost?
Most DIY installs run a few hundred dollars: the transmitter-and-collar kit plus wire, flags, staples, and splices. Professional installation uses separate installed-package pricing based on the project details.
What changes the cost of an underground dog fence?
Wire footage, the number of receiver collars, equipment tier, driveway crossings, surge protection, and whether you install it yourself or hire a professional all affect the total.
How much extra wire should I buy?
About 10% over your measured length. Splices, layout changes, and future repairs all consume wire, and running short mid-install forces a splice you did not need.
