I did Tanner's first trial when he was 11 months old. The first day he was a rock star and the second day he fell apart. In retrospect, he would have been better served if I had just entered the first day and then waited a few weeks to enter another trial. He was so strong on sheep, despite his age, it was too easy to forget that he was still a fairly green dog.
If you do decide to focus on something other than herding for the next little while, make sure that you won't have to spend time undoing anything once you go back to herding. The kind of obedience you need for herding isn't the same kind you need in other sports. A dog who is spending all their time staring at you and needing "quality eye contact" might need to wean off that attribute in herding. I learned that the hard way when I made the switch from obedience training to herding when Tanner was about 7-8 months old.
I backed Tanner off working sheep for several weeks after his crash and burn that second trial day. During that time I had him out on a long line, doing a lot of long distance downs and working on his ability to listen when I told him to "wait". That was very helpful. And I also just had fun with him, without having some specific training goal in mind. We took a lot of "stop and smell the flowers" walks then. Well, we still do a lot of that now! Okay, that is mostly what we do now!
