Golden retrievers will lose teeth when they are 4 to 6 months old. If the puppies show poor eating and no appetite, they can mix some soft food (canned food for dogs). You can also buy some dog-specific chews to feed it. Golden Retrievers aged 7 to 9 months mainly grow their own fur. You must ensure that the fur is groomed for no less than 30 minutes a day. You can also feed Golden Retrievers hair beauty products (hair beauty oil, hair beauty powder).
