Such a greatly distended abdomen should be addressed by your veterinarian as soon as possible. It may be an aggressive tumor or fluid accumulation. Either can be quite serious given the size you describe. A physical exam, abdominal xrays and blood work should all be a part of the diagnostic process.

    On a young dog like BooJo, this swelling could be a cyst or an abscess considering it's been getting larger in a shoot period of time. It's unlikely to be a malignant tumor in such a young dog. I would have him seen by a vet first thing in the morning. The vet can diagnose what is causing this swelling and how best to treat it.
