The most obvious prenatal signs of golden retrievers are anxiety, shortness of breath, lowered body temperature, spinning in place, dark green mucus flowing out of the lower body, etc. When these symptoms appear, it means that the dog is about to give birth. Generally, dogs will give birth on their own, so the owner does not need to help. He only needs to observe from the side to avoid abnormal situations. It is necessary to supplement nutrition to the dog in time after delivery, and to prevent the dog from catching cold.
