Corgis, both the Pembroke Welsh and the Cardigan Welsh, are double-coated dogs with a dense undercoat and a weather-resistant topcoat. Their soft undercoat provides insulation against cold and heat, while the topcoat repels water, dirt, and debris. These dogs require regular brushing to manage their heavy, year-round shedding, but their double coat provides essential protection and temperature regulation. At Lillian Ruff, we offer a de-shedding dog shampoo to help with Corgi coat maintenance.
