Animals turn white when they get old, just as people turn white when they get old. The older you get, the worse your physical skills will be, and your ability to synthesize pigments will also decrease. Therefore, the hair will appear white, which is also a signal that the body is beginning to age. However, if your hair turns white at a young age, the reason may not be so simple. The main reasons are as follows:

First, albinism also exists in the animal kingdom, which has a certain relationship with gene mutation. Moreover, if animals have albinism, it is actually very precious, because the number of animals in this species may be very small or even non-existent. There are some white tigers, white monkeys or white deer, which are very rare. Albino animals often appear in dragon racks.

Second, the mental state of animals is not good. In fact, dogs are as emotional as people, and they are also prone to emotional diseases. For example, being abandoned by the former owner or being abused by others will leave deep pain in the dog's heart. In this way, the dog's mood is greatly affected, and it is always listless. General emotional illness will affect the health of the body, so it will eventually lead to problems in the dog's body, which in turn will lead to problems in the dog's metabolism. If melanin cannot be synthesized, white hair will appear early.

Third, the variety problem and the influence of food. Some dogs' fur really fades easily, especially when they have dogs. Generally speaking, dogs will be healthier if they eat professional dog food, but some people will give the food that people eat directly to dogs. Because salt is added to people's food, it will affect the hair growth of dogs, such as golden retriever and teddy. As long as the salt is ingested, the hair will fade, and many brown teddy and black teddy can be seen.
