At one of our local trails, we encountered a herd of about 30 cows. We chased the cows down the road for about 2 miles. The dogs had a blast! However, they were a little disappointed to turn around and come back to the truck, leaving the cows behind. Unfortunately, I didn't bring the camera! :( Well, now I know to bring my camera with me all the time because you never know what you'll run into!
