There are many causes of bloating in dogs and many are serious, so it is important to see a veterinary professional right away.
Bloat (Gastric Dilation Volvulus)
Bloat is considered by most experts to be the most emergent situation for a canine. This is a condition that happens when a dog eats too much or swallows too much air and the swollen stomach rotates and traps the gas inside the stomach. The other symptoms include circling, vocalizing, trying to vomit, depression, and anxiety. This condition is more common in older dogs and large dog breeds with deep chests such as:
- Standard Poodle
- Gordon Setter
- Akita
- Basset Hound
- Irish Setter
- German Shepherd
- Doberman Pinscher
- Boxer
- Weimaraner
- St. Bernard
- Great Dane
Intestinal Cancer or Other Tumors
Some types of cancer are more common in dogs, but the most common include:
- Intestinal (Adenocarcinoma)
- Liver (Hepatocellular Carcinoma)
- Adrenal Gland Cancer (Pheochromocytoma)
Heart Problems
Heart failure and some cardiac infections can cause a buildup of peritoneal in the abdominal area. Other signs of heart disease in your dog are coughing and breathlessness.
Internal Bleeding
This is usually caused by a trauma to the abdominal or chest area. Blood will build up and cause the stomach to swell.
Infection
An infection of the womb (pyometra) and other infections, can cause abdominal bloating as well. Some of the other symptoms you will see may include:
- Bloody vaginal discharge
- Excess thirst
- Loss of appetite
- Diarrhea
- Vomiting
- Parasites
Roundworms can cause the stomach to swell. This is a common condition in puppies but can affect a dog of any age and breed.
Poisoning
There are numerous things that can cause poisoning in dogs, and that includes everyday items that we use every day such as seasonings and vitamins. Other items that can cause bloat are chocolate, some plants, medications, and even some bugs.
