In the early stage of pregnancy, although the female dog's breast tissue and uterus have developed properly, it does not need to increase the dog's energy supply. The last three weeks of the dog's pregnancy are the important period. Overfeeding in the early stage of a dog's pregnancy will inevitably lead to fat deposition of the female dog to prevent difficult delivery.
The most reasonable feeding method for dogs to become pregnant is to increase the weekly feeding volume by 15% from the 5th week of pregnancy, and the feeding volume of female dogs during childbirth is 60% more than when they are mate.
If the dog has a large number of pregnancy, its appetite may decrease in the week before delivery or 7-10 days before delivery due to a larger abdomen and a decrease in exercise. At this time, a small amount of meals is a good idea. The purpose of scientific feeding is to prevent female dogs from being overly obese, maintaining a normal appetite and meeting the needs of mother and son due to nutrition. About 2 days before delivery, the female dog's nipples sag, and a small amount of milk can be squeezed out.
Under normal conditions, the dog's breastfeeding period is 45 days, and under normal circumstances, the weaning period for puppies is also about 40 days. Within 2 weeks after birth, the puppies spend their meals and sleeps, and usually open their eyes around 7-13 days.
