• hair remains on the snout, around the legs, tail, and on the belly and the vibrissae are normal
• in the adult the coat appears unkempt and becomes progressively thinner with age, and more hair loss occurs in aging females than males
• guard hairs are thin and few in number
• very few zigzag hairs are found and those that are found have no medulla
• at 11 days of age the hair begins to thin around the eyes, top of the head, and nape of neck and by 21-25 days of age the dorsum becomes bald except for very fine stubble, yet hair remains on the snout, around the legs and tail and on the belly
• at 28 days of age the hair begins to re-grow on the dorsum and during successive hair cycles the dorsum is never devoid of hair
