I am very sorry to hear about your dog. She definitely needs to go see a veterinarian as soon as possible. Swelling of the abdomen as you describe can be from many causes including fluid buildup in the abdomen (due to things such as heart disease, liver disease, low protein levels due to kidney loss or intestinal loss or severe intestinal parasitism), tumors in the abdomen as well as tumors that are bleeding or oozing into the abdomen. The vet will palpate your dog's belly and may recommend testing including a fecal test to check for parasites and bacteria, an x-ray to look for fluid and tumors, and bloodwork to check protein and red and white blood cell levels.

    If he is retching like he wants to vomit but cannot, take him to the vet IMMEDIATELY, as this could be a sign of a possible GDV (twisted stomach bloat) which is a surgical emergency. Likewise, if he is very weak, if his gums appear pale, or his cannot rise on his own, take him IMMEDIATELY, as this would concern me for a possible hemoabdomen (bleeding into the abdomen, often caused by a ruptured tumor on the spleen; this too is life threatening and time sensitive. Fluid buildup in the abdomen is possible as well and can occur for a number of reasons. The following are some possible causes: -liver failure -low proteins -cancer -heart failure -fluid around the heart -heartworm disease Other possible causes for a distended abdomen that occur more gradully can include: enlarged liver weight gain cancer Regardless of the cause of the appearance of his abdomen, you do need to have him seen by a vet very soon. Please refer back to the first 2 paragraphs and take him to a vet ER if he falls into either of those categories. Thanks for using Petco Pet Education Center, formerly Petcoach!

    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.

    Swelling or fluid accumulation in the legs and abdomen typically indicates a serious problem. Your dog may have heart disease or organ failure -kidney or liver-. This can also be seen with certain types of malignant cancers. Your dog should be seen right away for an exam and diagnostics which may include general bloodwork, a heartworm test, abdominal and chest X-rays and they may even recommend an ultrasound. Please have Hustler seen as soon as possible to determine what needs to be done.
