Most coats are short and glossy, fine and close, but many young dogs develop a "puppy" coat which is somewhat longer and a bit fuller than the coat would be at maturity.
They tend to keep this slightly rougher coat until a year of age, when it begins to shed and is replaced by a finer, closer coat. A small percentage of Pharaoh Hounds, after shedding the puppy coat, will grow a slightly longer, slightly harsher coat. This is acceptable if the variation is slight. Feathering is a fault.
