Japanese Chin Question

The color of a Japanese Chin is either black and white (including those with tan points or "tri-color") or red and white, which includes all shades of lemon and white and sable and white. A Chin may "grey out" on their face at a young age - sometimes before three years of age, but they should retain their black body markings in a true black color. "Blue" or dilute black and white are not allowed and are discourged in the breed. You can look at your dog's nose color to determine if the dog is "blue" or a greying black. In all black and white dogs (even with tan points) the nose must be black in color. If it is grey in color, you have a blue dog. Red and whites can have a "self-colored" nose which can range in color from deep brown to a mottled pink. I hope this helps answer your question.

The gray and white you are referring to is called ticking and disqualifies for showing, but certainly does not affect the personality of a pet Japanese Chin.
