You should do this with any breed you are thinking of owning and many of these cautions apply to many other breeds as well. Beardies need lots of grooming. And this is no joke. 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.
