You are absolutely right. Genetics determines when he breaks color, what kind of coat he'll have, and the end result of his coat color. The only way I could think of that you could ruin your baby's coat is if you chemically process it, or you style it with heat. Yorkies have hair, much like a human does. You should be brushing your baby often, min of once a day. For now use something like a baby brush just to get him use to a nightly brushing ritual.
