Pets have become an integral part of people’s lives in today’s modern world. With the growing trend of pet ownership, pet lovers have become more attached to their pets (World Travel Market, 2007). Owners tended to include their pets while holidaying. This study examined the personality of dog owners and whether this influenced their pet attachment levels. In addition, this study also investigated what influences dog owners to bring their dogs when travelling and to what extent pet attachment influences their travel behaviour. A total of 151 questionnaires were completed via face-to-face, online forums, and Facebook groups. Multiple linear regression analysis was used in this study to assess the relationship between pet attachment, travel behaviour, and personality. The results supported the hypothesised model: that pet attachment has a positive effect on travel behaviour; and that proposed moderating effect of personality in the relationship between pet attachment and travel behaviour. It is expected that the results of this study will provide a useful reference for academics and hotel and tourism managers. Moreover, this study can provide the hospitality industry with valuable information for developing the pet travel market.
