The objective of this study was to explore whether companion canine traditional Chinese veterinary medicine (TCVM) Five Element personality type (Wood, Fire, Earth, Metal, Water) could be determined by a questionnaire and in agreement with a TCVM clinician. The study designed an experimental questionnaire which used word association with 25 descriptive personality adjectives (Canine Five Element Personality Questionnaire) to identify a dog‟s Five Element personality type. The questionnaire was given to dog owners or an individual very familiar with the dog to fill out while waiting for a veterinary appointment. Questionnaire accuracy was evaluated and its significance assessed by correlation of its results to a Five Element personality diagnosis given by a TCVM clinician. Results from the study demonstrated that the experimental questionnaire when compared to an experienced TCVM clinician‟s assessment matched 50 out of 89 dogs. This was a 2-fold greater correlation (56.2%, range: 42.9-65% for each Element) than chance association (20%, p=6.14×10^-14). This study concludes a personality questionnaire may be a useful tool to help determine Five Element personality types in companion canines.
