Australian Shepherds have a double coat, with a thick, insulating undercoat and a weather-resistant topcoat that protects against the elements. This breed requires regular brushing to prevent matting and manage its significant shedding, especially during seasonal changes, when its coat adjusts to stay cool in the summer and warm in the winter. For Australian Shepherds, Lillian Ruff provides a de-shedding dog shampoo to help with maintenance.
