Dig a 12-inch trench along the perimeter where you want your fence using a shovel.
Dig fence post holes 24 inches apart using a post hole digger. Dig them 18 inches deep.
Install 4-inch fence posts in the fence post holes.
Fill the fence post holes with dirt using the shovel, packing the dirt tight with the shovel while also ensuring each fence post remains vertically straight using a water-bubble level.
Clamp fence slats horizontally onto the fence posts using wood clamps. Position the top slat 1/2 inch from the top of the fence post and the bottom slat 4 inches above the ground. Space the slats every 4 or 6 inches while ensuring the slats remain level using the bubble level.
Drill 1/4-inch bolt holes through the slats and fence posts using a power drill fitted with a 1/4-inch drill bit.
Secure the fence slats to the fence posts using the 1/4-inch bolts, nuts and washers, and tighten them with a 1/4-inch ratchet. Make sure each bolt and nut receives one washer between the nut.
Wrap a sheet of chicken wire around 1/2-inch pipe, so the pipe lays in the bottom of the wire like a person resting in a hammock. Ensure both sides of the wire remain equal.
Lay the pipe along the bottom of the 12-inch trench between the fence posts.
Staple the chicken wire to the lowest fence plank using the staple gun with the pipe resting in the bottom of the 12-inch trench.
Fill in the trench with dirt, cover the pipe and fill it in around both sides of the chicken wire. This chicken wire will serve as a barrier in case your dog wants to dig, and the pipe buried at the bottom of the trench will provide resistance to keep the dog from digging the wire out of the ground.
