It's not normal that Luna's belly is swollen a week after breeding, and i would be concerned that the swelling could be due to a medical illness such as a pyometra (infection of the uterus). She could also be suffering from intestinal worms, bloat, or have a build up of fluid in the abdomen from a disease process. I would have Luna seen by a vet immediately for this, as there can be some very serious causes behind a suddenly swollen belly. The vet can do a physical exam, blood tests, urinalysis, and x-rays to diagnose what is causing her swollen belly. Once the cause is found, the vet can discuss treatment with you. Please take her into a vet now.
