The correct double coat consists of a downy undercoat with an outer layer of longer, coarse guard hairs. Light rain does not penetrate the guard hairs easily and mud tends to dry and fall out of the double coat. This coat doesn’t need extensive care, but a weekly brushing keeps shedding manageable. Regardless, the coat does shed in spring and fall. Plush coats are slightly longer, and, as the name implies, are plusher in look and feel. Longhaired coats may have an undercoat and tend to be very soft. The silky, longhaired coats require more care to prevent tangling. The longhaired coat can be quite beautiful.
Despite its exotic look, this coat is not rare or worth more money. German shepherd puppies have a fuzzy coat that will shed and be replaced by an adult coat around the age of four months. Additionally, you can expect that the adult shepherd will shed heavily twice a year, in the spring and again in the fall, although the exact time depends upon your climate and the German shepherd’s living conditions. During seasons when shedding is low, shepherds with a double coat will require only a weekly brushing to maintain a clean, smooth coat. Longhaired German Shepherds should be brushed on a daily basis.
