In this 2017 longitudinal study, E. Cohen examined how early maternal behavior, young adult temperament, and cognitive skills interact to influence long-term outcomes in prospective guide dogs. Data were collected from birth through adolescence, enabling researchers to track developmental patterns and their relationship to training success.
Maternal style was observed in 21 mother dogs and quantified through behavioral assessments. Findings showed that maternal behavior could be summarized in a stable principal component, which varied between individuals and was linked to cortisol levels and experimental indicators of maternal stress and engagement.
An important finding was that dogs from less-involved mothers were more likely to succeed in guide dog programs. These dogs later demonstrated strong problem-solving skills, lower perseveration, and reduced anxious vocal behavior as adolescents. This suggests that moderate maternal involvement may promote independence, resilience, and adaptive learning in working dogs.
Young adult temperament and cognition were also found to be significant predictors of program outcome. Successful guide dogs showed better cognitive flexibility and emotional regulation, emphasizing the role of balanced temperament and efficient problem-solving ability in working roles.
In the final phase, Cohen evaluated whether cognitive and temperament traits could be clearly separated. The study revealed that such distinctions are not rigid; rather, cognition and temperament interact in complex, overlapping ways that influence how dogs respond to training and environmental challenges.
The research concludes that both early-life maternal experiences and adolescent behavioral traits contribute to future working success. The interplay between resilience, cognition, and emotional regulation may provide better predictors of guide dog suitability than traditional single-domain assessments.
