Though Cane Corsos have a short coat, they are a double-coated breed with a light undercoat that thickens in winter to provide insulation. This breed sheds heavily, especially during seasonal changes, helping protect their skin against extreme heat and cold. It is important to brush Cane Corsos weekly to remove any hair that may be trapped in the undercoat, which will vary in density depending on the climate. Lillian Ruff formulates de-shedding dog shampoo for Cane Corsos and other double-coated dogs.
