Dog Run tips
Pea gravel is a common dog run surface because it drains and is easy on paws; some dogs dig in it, so edging and a deeper layer help. Rinse the run regularly, and pick stone without sharp edges.

Before the stone goes in
Clear vegetation, rake the soil level and compact it. Lay fabric overlapped at the seams and set edging before spreading the stone.
Buying the stone
If you haul it yourself, a typical half-ton pickup should carry only about half a cubic yard of stone, well under what the bed looks like it can hold. Gravel is a broad label, so confirm whether the yard means crushed or rounded stone and whether it carries fines. Round up by about 10 percent for compaction and uneven ground.
Planning the cost
Quarries and landscape suppliers set their own prices, and they change by region and season. Get the price per ton, the delivery fee and the minimum order. If two products will both work, compare cost per square foot at your depth rather than cost per ton.
Measuring the area
Use a long tape and measure each side twice. If the ground slopes, measure depth at the high and low ends and average them. Irregular outlines can be broken into simple rectangles, triangles and circles; add the pieces for the total square footage before converting to tons.
