Intrinsic to the development of modern zoo designs are the interwoven concerns of naturalism and animal welfare. Animal welfare, in particular, has become the paramount responsibility for professionally run zoological institutions as they seek to become centers of conservation and education without compromising animal wellbeing. Animal welfare and naturalism (understood as a design feature in zoo exhibits) are typically harmonious objectives, but these goals have occasionally clashed in implementation. While animal welfare and naturalism are defined in various (and not always consistent) ways in the literature, in-depth interviews of leading professionals and scholars in the zoo community and multi-dimensional case studies of exemplary, accredited institutions (including the Phoenix Zoo, the San Diego Zoo, Woodland Park Zoo and Arizona-Sonora Desert Museum) provide unique insight into the shifting meaning of these terms and how welfare and naturalism have and continue to shape the
development of modern zoo enclosures. This study concludes by suggesting a possible
future trajectory for innovative and alternative zoo designs that incorporate both animal welfare and naturalism without sacrificing either goal.
Four suggestions from the findings of this dissertation that will likely better the lives of dogs living in animal shelters are: 1) Shelter dog breed heritage is complex and visually identifying multiple breeds in a mixed breed dog is difficult at best. Shelters should instead focus on communicating the morphology and behavior of the dogs in their care to best support adopters. 2) While encouraging walking did not influence owner behavior, adopters who reported higher obligation and self-efficacy in dog walking were more active with their dogs. Thus, post-adoption interventions that can effectively target owner perceptions of obligation and self-efficacy may be more successful in changing behavior. 3) Temporary fostering is an impactful intervention that reduces stress for dogs awaiting adoption; however addressing stressors present at shelters that are likely contributing to higher stress responding is also needed. 4) It is possible to predict the internal stress responding of shelter dogs by observing their overt, in-kennel behavior, and this study is a first step in assessing and improving the welfare of dogs living in animal shelters.
Many Americans are sentimental about horses and believe that American horses deserve special treatment under the law for their important roles in American culture and history. In 2006, the House of Representatives passed a bill, known as H.R. 503, to end horse slaughter for human consumption in the U.S., and the following year in 2007, the horse slaughter ban began in the U.S. In this paper, the ineffectiveness of the horse slaughter ban to protect unwanted horses in the U.S. is demonstrated. More horses have been transported to less-humane slaughterhouses in Mexico and Canada, and more horses have been abandoned, abused, and neglected in the U.S. since the horse slaughter ban began. It is important to consider how American sentiments about horses contributed to H.R. 503 to better understand the ineffectiveness of the horse slaughter ban. People who were in favor of H.R. 503 relied on animal rights arguments, which tend to be more emotional than animal welfare arguments, by appealing to American sentiments about horses. The public increasingly believes that animals have rights. If animal rights activists do not find ways to protect unwanted animals, their ideas can infringe on animal welfare.
