Either you will have to learn to groom like a professional, have them groomed by a professional, or clip all that beautiful hair. Under 2 years is the worst time. Grooming can be once or twice a week. Later this can be every two or even three weeks. You need really good combs, brushes, mat rakes and so on.
Good grooming keeps the extra hair from ending up on the carpet.
Not that Beardies shed more than other dogs - in fact short hair dogs tend to shed a lot more. But the long hair will wrap itself up in the rollers of the vacuum cleaner. You want it to end up on your brush instead. With their long hair, Beardies can track in mud, leaves, all sorts of unusual materials stuck in their coat. For that matter, they may just rub it off on you.
