A more youthful modification of the famed Collier de Chien (CDC), the Hermes Kelly Dog was introduced around 2000.  Made of leather or skin and accented with either gold plated or silver/palladium plated hardware, this bracelet features a similar style to the famed Collier de Chien without the Studs.  The Kelly Dog (sometimes referred as "KD") is one size, but adjustable with three slots and a toggle closure.   The more recently introduced Kelly Dog Extreme is a wider version of the Kelly Dog and features the same closure but with six small studs -- three at top and three at bottom.
