Biewers require a good deal of grooming if you intend to keep them in long coat. Even though the coat is long, it does not carry the type of thick undercoat that a Shih Tzu has, so matting should be minimal. A weekly bath and brushing every other day will keep them in good condition.   Never brush a dry coat, always mist the coat or spray the brush with a finishing product to prevent pulling and/or breakage.  The hair on the head should be tied up out of the dog's  eyes with a small rubber band. A bow is not required, but is part of the fun of owning one of these glamorous little canines. Keep the hair around the feet, tummy and anus trimmed (hygiene clip).  The ears should be trimmed in an inverted V to include one third of the ear. They can be kept in a shorter trim, much like a puppy coat, with or without a top knot.
