Ascites in Dogs: Why Your Dog’s Belly Might Be Swollen
Ascites is a condition where fluid piles up in a dog’s abdomen. It is also called abdominal effusion and can cause a visibly swollen belly, plus a lot of discomfort. While ascites is not a disease in itself, it’s mostly always sign of a more serious underlying issue. The quicker you notice the symptoms and seek veterinary care, the better your chances of making a big difference in your dog’s health.
What Causes Ascites in Dogs?
Several medical conditions can lead to fluid buildup in the abdomen, but the most common are liver disease, heart failure, cancer, kidney disease, and internal bleeding or infection. When the liver isn’t functioning correctly, it can cause blood pressure in the vessels to increase and proteins to leak into the abdominal cavity, which leads to fluid accumulation. Heart failure, especially on the right side of the heart, can also result in fluid backing up into the body instead of being pumped efficiently. This causes swelling in the abdomen and limbs.
Cancers, especially tumors when present in areas like the abdomen or organs like the liver and spleen, can lead to fluid buildup. This is because they press against blood vessels or lymph nodes and prevent proper fluid drainage. Kidney disease can also interfere with the body’s ability to regulate salt and water, leading to swelling and fluid retention. Internal bleeding, an infection like peritonitis or trauma to the abdominal organs may lead to fluid accumulation as your dog’s body tries to respond to inflammation or injury.
Symptoms of Ascites in Dogs
One of the first signs pet owners usually notice is a bloated or swollen abdomen, and the swelling may come on suddenly or after some time, depending on the cause. More symptoms include difficulty breathing due to pressure from the swollen belly, lethargy or reduced energy, loss of appetite, vomiting, coughing or panting, pale gums and weakness or collapse in severe cases.
Noticing one or more of these symptoms is a sign that your dog needs to be examined by a veterinarian as soon as possible. Any delay can let the underlying condition get worse.
How Ascites is Diagnosed
A vet will usually begin with a physical examination of your pet, followed by diagnostic tests like x-rays or ultrasound to confirm fluid in the abdomen, then draw a sample of it to analyze and determine its cause. They might take bloodwork, urine tests, or heart scans as well, depending on the suspected root issue.
Treatment Options for Ascites in Dog
Treatment for Ascites aims at achieving two goals: relieving the built-up fluid and trying to eliminate the underlying cause. To reduce the abdominal swelling, vet doctors may perform a procedure where they drain the excess fluid using a needle, this usually relieves pressure, and the procedure is called abdominocentesis. Also, Diuretics, or water pills, may also be prescribed to help the body release fluid naturally.
The underlying condition must then be treated, and this might involve managing liver or kidney disease, providing medication for heart failure, or starting cancer treatment if there is a tumor. In some cases, your dog may need surgery.
