Every now and again I take the razor comb thing to it and shorten it back up, but other than that, Nothing. I usually do not even brush them, fingers run through only. When you only have a few mane hairs not worth risking loosing them in a brush.
So true AB! I put MTG in daisy's mane cause I would like it to be longer. But I don't brush it. It's not long enough to tangle. Her tail doesnt tangle either for some reason. So I don't mess with that either.
