This is quite worrisome in an older dog. She could have an abdominal mass or fluid causing the enlarged stomach. I recommend a veterinary exam and X-ray, and blood panel to see if there are any abnormalities. Once they find the reason for the weight gain then they can discuss treatment options. PleSe take her in soon to find the cause. Thanks for using Petco Pet Education Center, formerly Petcoach to help you care for your dog.
