Poor Marshall! It definitely sounds like something isn't right. There are many things that can cause a swollen stomach with weight loss and decreased appetite. Some possibilities would include heart disease, liver problems, cancer, or even internal bleeding. Treatment will depend on what the underlying problem is, so I would recommend taking Marshall to the vet as soon as you are able to. He/she can do blood work and x-rays if needed to help diagnose what is causing these symptoms, and will recommend treatment options depending on what is found.
