During the feeding process of the mother dog, timely weaning should be achieved. When the puppies are 42 days old, the mother dog basically stops lactating. At this time, the mother dog and the puppies can be managed separately, which is called "weaning" or "weaning". When the puppies are weaned, they must be checked and analyzed by animal B-ultrasound machine. In cold seasons, it can be postponed for about half a month. Experience has shown that timely weaning of puppies can protect them from bacteria and viruses carried by the mother and reduce the incidence rate. According to observation, most mother dogs have no milk at 40 days old and no longer let the puppies suck. The breeder can separate the puppies from the mother dog during the day and put them together at night. After 4-5 days of adaptation, the puppies can be managed separately from the mother dog. In this process, the animal B-ultrasound machine should be used to check their gastrointestinal conditions. In the first few days after weaning, the puppies are not used to it, and you should pay attention to observe the changes in the puppies to avoid accidents.

Management of puppies: Within one week after birth, puppies have poor mobility. The focus of care is to prevent the mother dog from stepping on or crushing the puppies, preventing the puppies from starving or freezing, and preventing the mother dog from biting (eating) the puppies. Therefore, it is important to use an animal ultrasound machine to observe the breast condition of the mother dog. The body of a puppy is easily soiled by dirt. The mother dog can lick it clean in time in the early stage. As the puppies grow, the caregiver should wipe the body of the puppies with a hot towel every day, which can not only keep the dog's body clean, but also stimulate the skin to promote blood circulation, enhance metabolism, and benefit the health of the puppies and promote growth and development. After 20 days, the puppies' toenails grow very sharp, which can easily scratch the mother dog's breasts, causing pain on the breast epidermis. The mother dog will no longer be willing to breastfeed the puppies. The caregiver should trim the puppies' toenails and use an animal ultrasound machine to check the breast condition of the puppies and the mother dog.
