The Chesapeake have a three layer coat the top coat has a oily way with it, similar to the old fishermans jumpers that had oil impregnated wool that kept the waterproof. Our chessie had the run of the house and on and of chairs no oily marks on anything,You can stoke them you will feel a oily way but nothing in your hand. the only thing I would say is not to many soapy baths or you will wash the oil away. they need it to be waterproof up to a point.
