The graying of Teddy's hair may be due to age and entering old age. At this time, the ability of the dog's body to produce pigment will decrease, and the nutrition of the hair will also decrease, so the color of the dog's hair will gradually become gray. This is a normal physiological phenomenon and the owner does not need to worry.

If the dog is still young and this situation occurs, the owner can appropriately supplement Teddy with some trace elements, vitamins and health care products to maintain the luster of the hair to see if the situation will be relieved.
