Hi, I can well believe that Afghans should not be brushed between baths. The same applies to my breed the American Cocker Spaniel.
The thing is, dirty hair gets pulled out in the brush. Wet hair is much stronger than dry hair, wet hair has a bit of stretch so doesn't break as easily. So all in all, a weekly bath and blow dry and a thorough grooming at the same time. After exercise, pick out any and all debris the coat has collected, and stress about the weather every morning
