In order to investigate genetic background of temperamental individuality in dogs, we analyzed polymorphisms of temperament-related genes in relation to the temperamental or behavioral scores evaluated by the trainers in guide dogs for the blinds and in detector dogs (both Labrador Retriever). As a result, "distraction", an important temperament for guide dogs and "obsession with rolled towel" for detector dogs, had tendencies related to a SNP on 5-hydroxytryptamine receptor 1B gene.
