Safety and security for your pet are now as close as your own back yard! Smart Dog® in-ground pet fencing systems set the standard for results you can trust. Not a rocket scientist? Don’t sweat it--installation is a snap in only three basic steps. Smart Dog systems consist of a buried yard wire connected to an indoor radio transmitter. When the dog approaches the wire, a special collar worn around his neck delivers a brief, totally harmless correction that discourages him from crossing the boundary. Patented run-through prevention is a standard feature on all Smart Dog systems. Corrections typically become less frequent as the dog learns his new limits. Dog training questions?

If your coverage area is larger than 1/3 acre, see chart below to calculate the amount of additional wire you would require.

Your "Underground Fence" does Not have to be installed underground! Save all the digging and cut your installation time in half! All you need is one box of Fence Staples (SS-100) for every 500 feet of wire you order for above ground installation.

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.

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.
