Mini Schnauzers have wiry coats, and depending on their skin sensitivity and activity level, they should be bathed every 4 to 6 weeks. Over-bathing can dry out their skin, but washing just their paws and beard rather than giving them a full bath can maintain their cleanliness during non-bathing times. This breed will need regular grooming and brushing to prevent matting and keep their beard and legs manageable; we recommend full grooming appointments every six to eight weeks.
