All puppies died in the first 2 days of life
It is difficult to determine the cause of the death of all puppies in the first 2 days of life. It is usually caused by congenital problems. The mortality rate of newborn puppies is extremely high. Most of the causes of death are insufficient blood oxygen, such as premature separation from the placenta or disconnection of the umbilical cord. Underweight puppies at birth can cause a high mortality rate, and lack of nutrition in the mother's uterus is an important reason why puppies are born too small.
