The aim of this study was to evaluate the status of missing information in case reports related to dog physical therapy in Japan. [Participants and Methods] Case reports published in Japanese academic journals from 1900 to 2022, which were identified using three electronic databases including Ichushi-Web, were included in this study. Information missing from the case reports was assessed using the CAse REport guidelines.[Results] A total of nine case reports were identified and they had a compliance rate of 100% for the item of type of therapeutic intervention. However, the compliance rate was less than 30% for 10 items in the abstract and main text.[Conclusion] The findings of this study suggest that there may be instances of misleading expression in Japanese case reports related to dog physical therapy.
