The purpose of this study was to explore the influence of pet dog attachment and perceived dog conflict on the acceptance of pet dog management regulations. Visitors' pet dog attachment, perceived dog conflict, and acceptance of dog management regulations were investigated in Da-An Forest Park, Taipei, Taiwan. The influence of pet dog attachment and the owners' perceived dog conflict regarding acceptance of dog management regulations were further tested. The study results indicated that owners' pet dog attachment negatively influenced their acceptance of strict dog management regulations; pet dog attachment negatively influenced perceived dog conflict; and owners' perceived dog conflict positively influenced their acceptance of strict dog management regulations. The study results may help park managers to understand owners' thoughts and to regulate pet dogs in parks.
