This sounds like she has intestinal parasites. Young puppies usually have roundworms and often hookworms and can have a swollen stomach as a result. Left untreated they can cause anemia, diarrhea and poor health in a puppy. You can purchase pyrantel dewormer at PetCo. Follow the label directions. I do also recommend a veterinary exam with fecal check and to start her vaccinations. Thanks for using Petco Pet Education Center, formerly Petcoach to help you care for Bella.
