When a dog is pregnant after breeding, her abdomen will begin to bulge, her nipples will become larger, and her vagina will be swollen and more fluid may flow out, just like in estrus. In addition, the bitch may experience slight vomiting and her appetite may be worse than usual due to the pressure of the fetus on her stomach. Generally for puppies, the pregnancy cycle is usually about 2 months, because individual puppies are different, some puppies will give birth in less than 2 months, while some puppies may also be 2 to 3 days later to give birth. In the first 30 days of a puppy’s pregnancy, its body changes are not too significant. But after this stage, the puppy’s abdomen will begin to bulge, especially after 45 days of pregnancy, its abdomen will bulge more.
