When does the Border Collie change its lanugo? When the Border Collie is three months old and its lanugo hair is almost all grown, it will start to change its lanugo. This stage usually lasts until the little Border Collie is six months old. During the moulting period, it should be fed every day. Groom your Border Collie, keep your home environment clean, and pay attention to supplementing your dog's nutrition.

There is very little fetal hair on a newborn Border Collie, but from birth to three months, the fetal hair will grow rapidly. When the fetal hair is almost three months old, the Border Collie will begin to change its fetal hair. This stage usually lasts until the little Border Collie is six months old, but some Border Collies develop more slowly and may still be moulting at eight months of age.

The time to change the fetal hair will be longer than the seasonal hair change in adulthood. If the owner wants the Border Collie to complete this stage faster, he can insist on combing the Border Collie twice a day. Combing can clean the fallen hair at one time, and can also promote blood circulation in the Border Collie's skin, making hair change faster.

In addition, attention should be paid to supplementing nutrients for Border Collie dogs during the hair shedding period. You can give dogs an appropriate amount of hair-beautifying foods such as carrots, cooked egg yolks, and lecithin powder to make the hair that Border Collies grow smoother and more beautiful. You should also pay attention to the cleanliness and hygiene at home, because the immunity of the Border Collie during the shedding period is relatively poor and susceptible to infection by parasites and skin diseases. Therefore, it is best for the owner to keep the home clean to help the Border Collie survive the shedding period safely. .
