Pregnancy can definitely cause a firm, distended abdomen. Lily's nipples also appear to be bigger than normal, which can indicate she is pregnant or had a litter in the past. There are many other causes of a distended abdomen, so it's best to have a vet check her out; especially if she is showing any other signs of illness. For further information about pregnancy in dogs, I recommend you read the article at the following link: https://vcahospitals.com/know-your-pet/breeding-for-pet-owners-pregnancy-in-dogs I hope that helps and all is well with Lily.

    There are many different causes for a dog's belly to get bigger, including pregnancy, false pregnancy, pyometra (life-threatening infection of the uterus), stomach bloat, free fluid in the abdomen, and cancer, among others. I would recommend that you have Sissy examined by a veterinarian as soon as possible for diagnosis. If she is not pregnant and otherwise healthy, your vet can schedule her for a spay surgery.
