 This study found that adding a supplement to a dog's regular food improved their performance in a field trial. The supplement appeared to reduce inflammation and improve muscle function, which may explain why the dogs performed better than those who did not receive the supplement. Further research is needed to confirm these results and determine if this supplement can be used to improve performance in other types of competitions. This article was authored by Janice L.
