I'll take it down if it wears out prematurely, but I try to leave it in as long as possible just because the more it comes down and goes back up, the harder it is on the tail and the hair. I try to mess with his tail as little as possible. Of course, when I take it down and it's long, soft, healthy, clean, and I can run my fingers through it, that's when I get my reward for my patience. With shows it'll come down more often, but I have a wedding to pay for this year, so it's likely there won't be any more shows this year. We went to one in February and he won his halter classes and his tail was only 2-3" on the ground at the time. Al of his hair grows so fast!
The wind of heaven is that which blows between a horse's ears. ~Arabian Proverb
