Visitors to many local, state, and national parks that include important natural and cultural resources are increasingly being visited by visitors with their companion animals, particularly domestic dogs (Canus familiaris Linnaeus). Visitors and their companion dogs are legitimate and welcome visitors to parks. Like all visitors and all uses of such sites, park managers are charged with minimizing impacts to park resources while also providing opportunities for visitors to enjoy and gain an appreciation for those resources. This paper describes a positive management technique for promoting leashing of companion animal dogs by visitors to a unit of the National Park Service located in the large urban setting of Jacksonville, Florida. Providing a positive and welcoming atmosphere for visitors with companion dogs can facilitate enjoyment and promote diligent care for park resources by this growing group of park visitors while minimizing potential impacts to resources as well as ensuring safety to all visitors, including their animal companions. This positive approach can additionally assist park efforts to create a sense of community among all its visitors.
