Research Abstract	With the aim of early predication of guide dog qualification, I examined temperament traits which had influence on guide dog qualification, and also searched for temperament-associated genes. A questionnaire survey on trainee dogs revealed that "Distraction" and "Docility" were consistently important for qualification. When these temperament scores and data from behavior tests (heart rates and behavioral responses) were employed for multivariate data analysis, guide dog qualification could be stably predicted with high accuracy (over 80%). Additionally, some genetic polymorphisms on neurotransmitter-related genes showed consistent association with "Distraction"and "Docility".
