    case name

extension Dog: ExtensionProperty {}

// Declare setter and getter to property

extension Animal where Self: ExtensionProperty {

    var name: String {

        get {

            return getProperty(key: AnimalPropertyKeys.name, defaultValue: "")

        }

        set {

            setProperty(key: AnimalPropertyKeys.name, newValue: newValue)

        }
