One of our yorkies was silky very early at age, and the other was black for a few years then BOOM she sure grew silver fast. They are both from the same bloodlines so def was hereditary.
I look at a picture of the one who was black for a few years to what she looks like now and she is a totally different dog, lol. Her coat now is so silky if you drop a hair in the sun shining in your window it will actually float through the air without dropping.
