Silvering is a recessive character that manifests itself by the appearance of many white hairs in the fur, chiefly on the back and sides. At birth the character is not apparent, gray hairs first appearing on the posterior region of the back when an animal is about four months old. The number of gray hairs increases after this age for the next three or four months. In high grade silvers there is a progressive increase in the amount of graying until the animal is about a year old.
