Outline of Final Research Achievements

In order to understand the quality of dogs which human feel comfortable in living with, we have developed a Japanese version of Kubinyi et al. (2009)'s dog personality scale. Since dog demographics and owner attitudes differ in Japan from Europe, some of the results differed, such as the structure of 'calmness', 'boldness' and 'dog sociability'.
Owner's preferences of dogs were those with 'calmness' and' boldness' rather than with 'dog sociability' or 'trainability'. This result is similar to that of Japanese parents' expectations of child being 'iiko' or being well behaved and good over being smart or independent.
Structural analysis of the canine FNBP1L gene revealed the presence of SNP in the 3 'noncoding region. Comparison of polymorphisms of FNBP1L and the dog personality scale and behavior tasks showed some relevances; dogs with A/A had higher trainability and calmness while dogs with G/A had less behavioral issues.
