If you have a white one, don't clip them real tight if you can help it. I don't think there is anything different about training Shorthorn hair...although there are a few different types. You can have a super hairy one, but it can just be plain HARD hair. We try to pick the softest haired ones, even if they don't have quite as much when they're young. It's just easier to train, and you can usually grow plenty of it. I guess that's like it is with any breed though. Just brush more than you think is necessary, and then do it some more!
