This PetSafe Boundary Kit will expand your in-ground pet fencing system. It includes 1000 feet of dog fence wire and 100 training flags.
Use the chart below to determine exactly how much wire you'll need based on the size of the area you want to secure. Keep in mind that creating interior loops to boundary off areas like gardens, swimming pools or other protected areas will use more wire.
This kit includes 1000 feet of boundary wire and 100 boundary flags.

For larger areas, use the following formula:
Multiply the total acreage by 43,000- i.e.: 10 acres x 43,000 = 430,000
Find the square root of the above number - square root of 430,000 = 656 (this is the length of each side of a 10 acre area that is square in shape. Even if your area is not square, if you multiply this number by four, this is the approximate length of the four sides of a 10 acre area.)
Therefore, one would need approximately 2,625 feet of wire to enclose the perimeter of a 10 acre area. You will need additional wire to run from the transmitter to the perimeter and/or for any interior loops, etc.
