The reason for the gray Tibetan mastiff's fur turning black

1. Genetic factors

The fur color of a dog is influenced by genes. For example, when a gray Tibetan mastiff and a black Tibetan mastiff are crossed, the resulting puppies are more likely to have black fur. This genetic expression of fur color is unchangeable, but it generally does not affect the dog's health, so owners don't need to be too worried.

2. Skin infection

A dog's fur may turn black due to a skin infection. When a dog contracts a skin disease, its fur may darken. To resolve this, it's essential to identify the cause and treat it with appropriate medication.

Additionally, feeding a Tibetan mastiff with a single or low-quality diet can lead to malnutrition and cause their gray fur to turn black. Therefore, owners should pay attention to the dog's nutritional balance and feed them high-quality dog food. Occasionally, feeding the dog with high-protein foods such as chicken and beef can meet their protein requirements.同时, you can also feed the dog with vegetables and fruits rich in vitamins.

Note: Due to the uniqueness of gray Tibetan mastiffs, it is recommended that owners pay attention to not only nutritional supplementation but also hair care. Regularly bathing and trimming the dog's fur can prevent it from getting dirty or knotted. It is advised to bath the gray Tibetan mastiff every 7-15 days and use pet-specific shampoo.
