In conjunction with the Canine Carnival, this premier event is something to bark about.  This 5K will extend along the Great Miami Recreation Trail, beginning and ending in Riverfront Park.  There is a limit of one dog per owner, and all dogs must be on a leash no more than six feet long.  No retractable leashes, please.  Water stations will be available throughout the courses to keep both dogs and their owners hydrated.  Packets can be picked up on race day at Riverfront Park beginning at 9:00 a.m.
