Simple SummaryHow people choose to acquire dogs and the characteristics they seek may provide insight into perceptions of ethical and socially responsible dog ownership, as acquiring a dog is the first step in dog ownership. Even if one does not intend to acquire a dog, perceptions of acquisition methods may impact views of pet industries and/or voting behaviors related to animal welfare regulation. This analysis (1) investigates the relationships between U.S. resident demographics and their level of agreement regarding statements related to dog acquisition and welfare considerations, (2) analyzes the relationships between U.S. resident demographics and their views on dog characteristics, and (3) analyzes U.S. residents’ relative ranking (in terms of most ethical) ways to acquire a dog. The findings of the current study affirm that appearance, compatibility with owner lifestyles, previous experience, and cost inform people’s decisions about dog acquisition. The relative importance of these criteria varied across respondents; as has been previously observed, women favored rescue/adoption more than men. Our results collectively indicate the growing appeal of adopting dogs from shelters and rescue organizations for many respondent segments. Different segments of the companion animal industry and those with different dog interests may want to consider tailoring their education and/or marketing communications to these groups accordingly. People’s preferences for where they acquire dogs and the characteristics they focus on may provide insight into their perceptions of socially responsible pet ownership, as acquiring a dog is the first step in dog ownership. An online survey of 1523 U.S. residents was used to aid understanding of public perceptions of dog acquisition. Likert-scale questions allowed respondents to assign a level of agreement, within the given scale, to ten statements related to dog acquisition. A significantly higher percentage of women (39.6%) than men (31.7%) agreed that the only responsible way to acquire a dog is through a shelter/rescue. More women (71.3%) than men (66.4%), as well as those with a higher household income (71%), identified source as important. Best-worst methodology was used to elicit perceptions regarding the most/least ethical ways to acquire a dog. Three subgroups were identified, one of which had an overwhelmingly large preference share (96%) for adoption. The second group had more evenly distributed preference shares amongst the various dog acquisition methods, while the third indicated a preference for “homeless” pets. Additional investigation of the values/beliefs underlying the preferences of these groups is necessary to design appropriately tailored companion animal-focused communication strategies for these different groups.
