Ruff'n It Day at Greene Valley Forest Preserve

Owners and dogs are welcome for exhibits, demonstrations and off-leash fun at the Greene Valley Forest Preserve, on the east side of Greene Road, north of 75th Street and south of Hobson Road, in Naperville. The event is free and no registration is required, but a valid, pre-purchased district permit to use the off-leash area is required for each dog. You can get a permit application here.
