When the dog is pregnant, don't give the dog fruits with high sugar, such as melons and cantaloupes, which may cause diarrhea. Moreover, it will cause obesity in dogs, which is very unfavorable to the production of dogs. Dogs can be supplemented with appropriate amounts of calcium and vitamins, because a lot of calcium will be lost in dogs during pregnancy, and postpartum hypocalcemia, such as convulsions, is likely to occur after pregnancy.
