Why is My Dog’s Stomach Swollen on One Side?

Why is My Dog’s Stomach Swollen on One Side?, Your dog’s stomach may be swelling on only one side due to a few reasons. It could be due to an infection, blockage, or a few other issues. In most cases, it’s best to take your dog to the vet to make sure everything is okay. However, if you observe the swelling and it’s not severe, you can try some of the following tips to help heal the problem on your own:

1) Give your dog plenty of fluids. Dogs naturally drink water, so it’s important to keep them hydrated. Thoroughly cleaning their dishes will help too.

2) Monitor your dog’s temperature. Overheating can contribute to fluid retention, so make sure they are kept cool and comfortable.

3) Give your dog comfortable bedding. This will help encourage them to relax and will help with their overall comfort.

4) Add foods that are high in fiber. This will help to bulk up your dog’s intestinal tract and help them to move things along more quickly.

5) Bathe your dog regularly. This will help to clean them and remove any potential dirt, oil, or bacteria which might cause an infection.

What can cause one side of stomach to swell?

It can be due to common gastrointestinal disorders like heartburn, constipation, or irritable bowel syndrome or disease, and these conditions typically bring discomfort and pain. More serious causes of abdominal swelling include intestinal blockage, fluid in the abdomen, or cancer.

Most dogs will occasionally show signs of being bloated. This could be caused by a number of things, and is not always a clear indicator of a health issue. However, if your dog’s stomach is swollen and on one side, there may be a health issue involved. Here are some reasons why a dog’s stomach could be swollen on one side:


The most common reason for a dog to become bloated is when they eat something that is too large for them, like a ham sandwich. The stomach expands, and if the dog doesn’t get relief from straining, they will die from asphyxiation.

Bloat is an emergency, and if you see any of these signs in your dog, get them to a vet immediately: extreme distension of the abdomen, gasping for air, rapid heart rate, whining or crying, lack of appetite, foaming at the mouth.

Pelvic Distress:

Sometimes a dog will get pelvic distress, which is a condition in which their abdomen suddenly inflates and makes them uncomfortable. This can be caused by a number of things, but the most common culprit is another animal, such as a cat, that the dog is protecting.

If you notice any of these signs in your dog, take them to a vet: whining, refusing to eat, a change in bowel or urinary habits, abdominal pain, pressure or discomfort when trying to walk.

Internal Tract Infection:

Another common cause of a dog’s stomach becoming swollen and on one side is an internal tract infection. This can be caused by bacteria getting into the dog’s intestines and then making their stomach swell. Signs of an internal tract infection include vomiting, diarrhea, poor appetite, weakness, and fever.

If you see any of these signs in your dog, take them to a vet: brown watery diarrhea, discharge from the nose or eyes, severe abdominal pain, fever, vomiting, lack of energy, unwillingness to eat.
