Are the hair follicles no longer cycling?

 
Hair loss may also occur because the hair follicles have stopped cycling. So as old hairs are falling out, new hairs fail to be produced to replace them. This results in a gradual and progressive loss of hair which is often symmetrical and involves primarily the trunk and hind legs. There is no inflammation associated with this type of hair loss so the skin does not appear red or crusty. Sometimes the fact that the hair follicles are no longer cycling is first noticed when your dog’s coat fails to regrow after clipping. Along with the hair loss, the skin may become intensely pigmented.
