How long does it take for a Border Collie to moult? Border Collie puppies begin to moult about 3 months after they are born, and this stage will last for 3-6 months. Adult Border Collies will undergo physiological moult twice a year, respectively. It is around March-May in spring and September-November in autumn. The duration of moulting is about one month.

Border Collie dogs usually start to change their fetal hair when they grow to about 3 months old. The duration of this molt may vary from 3 months of age to 8 months of age. Some Border Collies grow quickly and shed their hair quickly, while others grow slower. This has a certain relationship with the dog's own physique and growth environment.

Adult Border Collies will undergo two hair sheddings each year, around March to May in spring and September to November in autumn. This hair shedding time is relatively short, about one or two months. In spring, the Border Collie will shed its dense hair and grow sparse summer hair to welcome the hot summer; in autumn, it will shed its sparse summer hair and grow thick winter hair to adapt to the cold winter, so this is A physiological molt that occurs in response to climate change.
