Along with the increase in the number of households raising companion animals, ‘Pet-humanization’, which considers companion animals as members of the family, is emerging as a global trend. As the number of people who consider companion animals as companions and accompany leisure activities or travel continues to increase, traveling with companion animals is rapidly emerging as a new travel trend. In this respect, this study tried to find out the important attributes of travel with companion animals, and how these important attributes affect tourism value, satisfaction, and behavioral intention. A survey was conducted on tourists who had experienced traveling with companion animals within a year, and a total of 259 copies of the final valid samples were used for the final analysis. With the valid data collected by online survey, confirmatory factor analysis, and structural equation modeling were conducted. The important attributes that tourists consider when traveling with companion animals consisted of a total of four attributes: tourism service for companion animals, tourism facilities & contents for companion animals, availability of companion animals, and tourism cost. The results reveal that the tourism facilities & contents for companion animals was found to have a significant impact on tourism value. Furthermore, tourism value was again verified to have a significant effect on satisfaction of tourists. The findings of this study provide theoretical implications for academia and practical implications for industry practitioners.
