 The results of this study suggest that dietary fat may influence canine or faction. Specifically, dogs fed a diet rich in polyunsaturated fats were more likely to detect a target odor than those fed a high-fat diet. Additionally, dogs exercised prior to performing the test were more successful at finding the target odor than those who did not exercise. These results indicate that dietary fat and physical activity may both have an impact on canine or faction. Further research is needed to determine the exact mechanisms behind these effects.
