The purpose of this study is to extend and replicate previously published results from a random probability sample of university faculty. The sample assessed reasons given for companion-animal guardianship and for belief in the beneficial health effects of owning pets. In this replication and extension design, these two non-random samples responded to the same questionnaire items as those addressed to university faculty. Results indicated that avoidance of loneliness was the most frequent reason for owning pets among both students and middle-aged (...) community members. This result is consistent with the view that animals provide social support and companionship to humans at various stages of the life cycle. Suggesting an emergent feature of the human-nonhuman animal bond, both groups selected, “the pet helps keep me active” as the second-most common reason. Older women reported a greater belief in the health-giving benefits of pet ownership than did younger persons or men. This belief may contribute to human benefits of pet ownership and requires further research. (shrink)

This article explores the origin and evolutionary implications of anthropomorphism in the context of our relationships with animal companions. On the human side, anthropomorphic thinking enables animal companions' social behavior to be construed in human terms, thereby allowing these nonhuman animals to function for their human owners or guardians as providers of nonhuman social support. Absence of social support is known to be detrimental to human health and well being. Therefore, anthropomorphism and its corollary, pet keeping, have obvious biological fitness (...) implications. On the animal side, anthropomorphism constitutes a unique evolutionary selection pressure, analogous to sexual selection, which has molded the appearance, anatomy, and behavior of companion animal species so as to adapt them to their unusual ecological niche as social support providers. Although such species undoubtedly have benefited numerically from the effects of this process, the consequences of anthropomorphism are less benign when viewed from the perspective of individual animals. Indeed, anthropomorphic selection probably is responsible for some of the more severe welfare problems currently found in companion animals. (shrink)
