Pets are a part of the lives of many people in the world today. This study builds on previous research on characteristics of pet owners and the needs satisfied by their pets. We analyzed the motivational dominances of cat and dog owners and their relationship to the needs fulfilled by their pet. Fifty-six participants were recruited to complete the MSP (Apter et al., 1998) and a 45-item needs fulfillment survey constructed by the authors. Although no differences were found in state dominances between dog and cat owners, results revealed that dominances correlated with particular needs met by pet ownership. For instance, the extent to which participants felt their pets satisfied practical needs correlated with levels of arousal avoidance, conformity, alloic mastery, alloic sympathy, optimism, and effort. Social need satisfaction was correlated with telic dominance, arousal avoidance, conformity, autic mastery and sympathy, alloic sympathy, optimism, and arousability. Finally, emotional need satisfaction was correlated with telic dominance, arousal avoidance, conformity, autic mastery and sympathy, alloic mastery and sympathy, optimism, and arousability. These relationships help to form a more complete picture of pet owners, as well as the extent various dominance levels are related to the needs that can be fulfilled by pet ownership.
