A dog’s hair loss usually lasts about a month.

Dogs are animals that shed seasonally, and they generally shed hair in spring and autumn. When the seasons change from spring to summer, dogs will shed their thick hair to avoid heat stroke due to the hot weather in summer. When the seasons change from autumn to winter, dogs will grow thick hair to protect themselves from the cold in winter. Usually the speed of a dog's hair shedding is related to its physical condition. If the dog's hair loss lasts for more than a month, it may be due to malnutrition or skin disease. In this case, timely nutritional supplements or treatment of skin diseases will prevent hair loss. You can stop.
