Yorkies Coat colors have been known to change up to 2 years of age and on occassion even later than that. The Top Male Yorkie in the USA for 2003 had a very dark coat till he turned 2 yrs. old. His offspring are doing the same thing. They aren't turning steel blue till 18 months and older. The gold on the head also gets richer as they get older.
But no matter what her coloring, size, pet or show, she's yours to love for her entire lifetime.
