Stone for a dog run
For a dog run, rounded stone such as pea gravel is gentle on paws and drains fast. Lay it about 3 inches deep over fabric and edge the run so the stone stays put.

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.
Getting it delivered
Most quarries and landscape yards deliver by the ton; ask whether there is a minimum and a delivery fee, and where the driver can dump without damaging your lawn. Pea gravel is small and rounded, comfortable underfoot, and needs edging because it rolls. Ask your supplier for their own tons-per-yard number, since stone source and moisture change it.
Tools for the job
For anything bigger than a small path, rent a plate compactor; hand tampers cannot match it. A wheelbarrow, shovels, a hard rake and stakes with string are the rest of the kit. Wet the stone lightly before compacting so it binds.
Common mistakes
People often forget that compaction reduces volume, so they come up short. Others order clean, round stone where a packable crushed stone with fines would have stayed put. Finally, dumping the whole load in one pile far from the work area adds hours of wheelbarrow trips.
