Defining and measuring of attachment bonds: comment on Kurdek (2009).

Kurdek's study of dog owners raises a series of provocative questions about the nature of attachment bonds and whether dogs can serve as attachment figures for their owners. This commentary suggests that it is important to distinguish attachment from other types of affectional bonds that are motivated by caregiving, reproductive or affiliative concerns. It is suggested that preferences for attachment figures are best tested in situations involving danger and in situations in which preferences are not confounded with immediate physical proximity. Using these distinctions as a guide, this commentary concludes that although dog owners undoubtedly form affectional bonds with their pets, these bonds are more likely to meet criteria for caregiving rather than attachment bonds.
