If your yard is larger than 1/3 acre or if you have more than one pet, all you need is more wire and flags and an additional receiver for each additional pet.  See our wire calculator below to see how much wire you need.  This system is capable of enclosing up to 10 acres. Training flags are used to establish a visual boundary for your pet during training. After about 30 days, you will be able to remove the flags.

Use this guide to determine how much wire you need to enclose your yard. These figures are estimates, based on typical layouts. You may need more wire if you're doing interior loops to boundary off gardens, swimming pools or other protected areas. We will provide you wire in 500 foot increments on 500 or 1,000 foot spools.

To Cover This Size Area	You Need This Amount of Wire
1/3 Acre	500 Feet
1/2 Acre	600 Feet
1 Acre	1000 Feet
2 Acres	1300 Feet
3 Acres	1500 Feet
4 Acres	1800 Feet
5 Acres	2000 Feet

For larger areas, use the following formula: Multiply the total acreage by 43,560- i.e. 10 acres x 43,560 = 435,600



Find the square root of the above number - square root of 435,600 = 660 (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 2,640 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.
