1. The period from birth to weaning of a puppy is about 45 days. The main things to pay attention to during this period are: keeping warm, preventing pressure, and eating enough colostrum. (Newborn puppies cannot produce antibodies in their bodies, so they should try to eat enough colostrum.)

Two. Pay attention to development. It is best to weigh yourself regularly. Generally, within 5 days after a puppy is born, the daily weight gain will be about 50 grams on average. From 6 to 10 days, the daily weight gain will be about 70 grams. From 11 days onwards, if the mother's milk is insufficient, the puppy's weight will decrease. The growth rate may decrease. Regular weighing can help you understand the mother's lactation ability from the changes in weight, so as to decide whether to artificially supplement milk. Milk supplement: Mainly fresh milk or goat milk. After boiling and sterilizing, the baby should be fed with a bottle at a temperature of 20-30 degrees Celsius. Amount of milk supplement: Within 15 days, 50 ml of milk per animal. 100 ml of supplementary milk should be given on the 15th to 20th day. After 20 days, add 200 ml of milk. 3-4 times a day. (If fresh milk is not available, milk powder can be substituted with water.)

3. After the puppy is born: In the first 4 days after birth, check frequently to be careful of the mother dog crushing the puppy. After 5 days, when the weather is windy and warm, take the puppy outdoors to bask in the sun with its mother, usually twice a day, for about half an hour each time. Let it breathe fresh air, use ultraviolet rays in the sun to kill bacteria on the body, promote bone development, and avoid getting sick. When you can walk, you can go for a walk outdoors. The time should be short at first and can be gradually lengthened later. The puppy can only open its eyes around 13 days after birth. At this time, strong light stimulation should be avoided to avoid damaging the puppy's eyes. After the eyes begin to open on 9-12 days, the milk can be poured into the food plate for licking. (Although some puppies have opened their eyes, they still can't lick themselves.) Around 20 days, a small amount of rice soup and porridge can be added to the milk. After 20 days, when the weather is fine, let the mother dog take the puppies to the yard (provided you have a yard) for activities. The time is not limited, and they will return to the room in the evening or on rainy days. If the puppy gets wet in the rain, dry it immediately with a dry towel. Pay attention to keeping warm to prevent colds. The puppy's toenails can be trimmed once every 20 days to prevent the puppy from scratching the mother's breasts while feeding. After 25 days, some broth or vegetable soup can be added, and the amount can be gradually increased to about 200 ml. After 30 days, minced cooked meat can be added, 15-20 grams each time. After 35 days, the amount can be increased. On the 30th day, deworm the puppy with anthelmintics, and then deworm it once a month. Generally, weaning takes 1 and a half months to 2 months.

Note: Supplementary food can be mixed with milk, eggs, minced meat and pasta or rice to form semi-solid food. At the same time, appropriate amounts of cod liver oil and bone meal can be added. 4-5 times a day.

Note: Puppies tend to get dirty things on their bodies. At first, the mother will lick them off at any time, but when they get older, they will ignore them. Someone needs to wipe and bathe them frequently, once every 2-3 days.
