The harsh, straight, short-haired double coat is fairly easy to groom and sheds little to no hair. Simply brush regularly with a stiff bristle brush. Brushing should keep the coat clean, so bathe only when necessary. Trim around the ears and eyes with blunt-nosed scissors. The whole coat should be trimmed about every 2-3 months dependant on style.
Most people have a traditional Westie trim with feathers / furnishing this can be with or without skirt.
