Here's why:
* Coat Color Genetics: Yorkies have a gene that produces a pigment called phaeomelanin, which gives them their characteristic gold or tan coloring. This pigment fades over time, making the coat appear lighter.
* Coat Care: Regular grooming and bathing can also affect the appearance of a Yorkie's coat. Using certain shampoos or conditioners can cause a slight change in color, but this is usually temporary.
* Health: In some cases, a Yorkie's coat may turn gray or silver as a result of a health condition, such as hypothyroidism, which can affect pigment production.
It's important to consult a veterinarian if you notice any significant changes in your Yorkie's coat color or texture. They can help determine the cause and recommend any necessary treatment.
