Depending on the level of competition, containers of any type (such as boxes, empty paint cans, luggage, etc.) may be used and may be set in any arrangement. There can be one odor hidden in one container, or multiple odors in multiple containers, as well as distractor-odors (such as food, toys or animal smells).
The search is usually conducted indoors, on-leash.
