The first molting period of a golden retriever as a puppy lasts about 3-4 months. After reaching adulthood at 1 year old, the golden retriever will have a molting period in spring and autumn, each lasting about a month. However, golden retrievers cannot avoid shedding. Even if they are not in the moulting period, a small amount of hair loss will occur. Therefore, owners should groom their golden retrievers frequently and feed them lecithin-rich foods, such as cooked egg yolks, etc. Maintain your dog’s coat.
