The preferred method of grooming involves starting from the base of the hairs to keep the thick undercoat hair mat- and tangle-free. The brushing should be started at a very young age to get the dog used to it. A hairband may be used to keep a dog's fur out of its eyes. Many people trim their dogs' coats to a more manageable length. A professional quality electric shear reduces time spent trimming. However, dogs that are being shown in conformation must retain their natural coat.
