Jan 07,2025 | puaintapets
If you’ve noticed that your dog’s belly appears swollen or bloated, you may be understandably concerned. Abdominal swelling in dogs can be caused by a range of issues, from minor gastrointestinal problems to more serious, life-threatening conditions. In this article, we’ll explore the various causes of belly swelling in dogs, the symptoms to watch out for, and what you can do to help your dog.
What are Causes of Swollen Tummies in Dogs?
I. Dietary factors
- Overfeeding
Dogs that consume too much food at one time, especially high fiber, high starch or easy to produce gas food (such as beans, potatoes), the stomach and intestines can not be digested in a timely manner, the food will be piled up in the stomach and intestines, resulting in a swollen stomach.
- Swallowing foreign objects
Dogs may accidentally ingest foreign objects such as toy fragments, bones, fabrics, etc. when playing or exploring. These foreign objects accumulate in the gastrointestinal tract, which not only take up space leading to a swollen tummy, but may also cause intestinal obstruction, with severe abdominal pain, vomiting, and stopping of bowel movement, among other symptoms.
- Inadequate water intake
Long-term insufficient water consumption will affect the dog's digestive function, so that the food in the intestinal tract to lengthen the retention time, indirectly increase the risk of tummy swelling.
II. Digestive System Diseases
- Gastroenteritis
When the dog suffers from gastroenteritis, the gastrointestinal mucosa is damaged, the digestion and absorption function is weakened, and the food is retained in the gastrointestinal tract and fermented, producing a large amount of gas, which causes a swollen stomach. At the same time, it may be accompanied by vomiting, diarrhea and other symptoms.
- Intestinal obstruction
Foreign bodies, tumors, intussusception and other causes can lead to intestinal obstruction, so that the intestinal contents can not pass through normally, accumulating above the obstruction area, causing the stomach to swell. Intestinal obstruction is an emergency and requires immediate medical attention.
- Parasitic infections
Certain parasites (e.g. roundworms, hookworms) are parasitic in the dog's intestinal tract, and when they multiply in large quantities, they will occupy the intestinal space, affecting the normal digestion and absorption of food, resulting in a swollen tummy. In addition, parasites may also cause diarrhea, anemia and other symptoms.
III. Other Factors
- Liver disease
The liver is an important metabolic organ in the dog's body, responsible for producing bile to help digest fat. When the liver is damaged, bile secretion is insufficient, fat digestion is poor, easy to accumulate in the intestines to produce gas, causing stomach swelling. Also, liver disease may be accompanied by symptoms such as jaundice and loss of appetite.
- Heart disease
When the heart is not functioning properly, the dog's circulation is stagnant and the venous return in the abdominal cavity is obstructed, resulting in the accumulation of fluid in the abdominal cavity (ascites), which is manifested as a distended abdomen. Heart disease is usually accompanied by symptoms such as difficulty breathing, coughing, and exercise intolerance.
- Peritonitis
Peritonitis is a disease caused by inflammation of the organs in the abdominal cavity spreading to the peritoneum. The inflammation causes the peritoneum to become congested and edematous, oozing large amounts of fluid and forming ascites, which causes the stomach to swell. Peritonitis is often accompanied by severe abdominal pain, fever, and loss of appetite.
- Pregnancy
In female dogs that are not spayed and have been in heat, a swollen belly can be caused by pregnancy. The development of the fetus in the uterus during pregnancy causes the abdomen to gradually increase in size.
How to Treat a Swollen Belly in Dogs?
The treatment for a swollen stomach in dogs depends on the cause of the swelling. Here are some common treatments.
I. Dietary adjustments
-
Reduce the amount of food
If your dog's tummy is swollen due to over-eating, reducing the amount of food is the first measure. You can divide the daily amount of food into multiple feedings to avoid consuming too much food at once.
-
Adjust food type
Avoid feeding gas-forming foods such as beans and potatoes. You can choose easy-to-digest dog food or prescription food specifically for dogs with sensitive stomachs.
II. Medication
When the dog's stomach is swollen due to indigestion, probiotics can be used to regulate the intestinal flora and promote digestion. Probiotics can improve the intestinal micro-ecological environment, enhance gastrointestinal peristalsis, help digest food, and reduce the fermentation of food in the intestinal tract to produce gas.
-
Dewormer
If you suspect that your dog's swollen stomach is caused by a parasitic infection, you need to treat it with deworming medication. Different parasites require different deworming medications, for example, roundworm infections are commonly treated with medications such as albendazole, and hookworm infections are commonly treated with medications such as mebendazole. When using deworming medication, the dosage needs to be calculated accurately according to the weight of the dog to ensure the deworming effect and avoid adverse drug reactions.
-
Tachycardia tablets or tachycardia injection
When your dog's stomach is swollen due to ascites or other causes of fluid retention, you can use a fast-acting diuretic or a fast-acting urinary injection to promote urine drainage and reduce swelling. Tachycardia is a potent diuretic that increases the excretion of water and electrolytes by the kidneys, thus reducing the amount of fluid in the body.
III. Surgery
-
Surgery for gastric torsion
If your dog develops gastric torsion, it is an emergency situation that requires immediate surgical treatment. The purpose of surgery is to restore the twisted stomach to its normal position and immobilize it to prevent it from twisting again. Gastric torsion will cause the gas and liquid in the stomach to not drain properly, causing the stomach to become severely distended. If surgery is not performed in a timely manner, the dog may die due to ischemia and necrosis of the organs.
-
Drainage of ascites
When a dog has ascites, ascites drainage surgery may be necessary. Ascites is removed from the abdominal cavity through a puncture to reduce pressure in the abdomen and relieve swelling. It is also necessary to treat the cause of the ascites, such as liver disease and heart disease.
IV. Other Treatments
-
Massage
For tummy swelling caused by indigestion or mild flatulence, try gently massaging your dog's abdomen. The direction of massage should follow the direction of intestinal peristalsis, gently massaging from the stomach to the anus, which helps to promote intestinal peristalsis and help gas discharge.
-
Hot compresses
Hot compresses can promote local blood circulation, relieve abdominal muscle tension and reduce discomfort. You can use a towel soaked in warm water or a special hot compress bag to gently apply it to your dog's abdomen, but be careful not to use too high a temperature so as not to burn your dog's skin.
