Symptoms of canine gastritis

The main symptoms of gastritis in dogs include vomiting and abdominal pain, but other signs of the disease may also appear. The most common symptoms of this disease in dogs are:

  • Severe and persistent vomiting in chronic gastritis . They may have bile (yellow), fresh (dark red) blood, or digested blood (dark grains such as coffee beans).
  • Sudden and frequent vomiting of acute gastritis . They may also have bile, fresh blood or digested blood.
  • Vomiting with white foam – when the animal no longer has anything in the stomach
  • Abdominal pain that can range from mild to severe.
  • Loss of appetite.
  • Weight loss.
  • Diarrhea.
  • Dehydration.
  • Weakness.
  • Lethargy.
  • Presence of blood in the stool.
  • Pallid mucous membranes due to blood loss.
  • Yellow mucous membranes due to ingestion of toxins.
  • Baba.

Causes and risk factors

The acute gastritis is almost always associated with the ingestion of harmful substances to the dog. It can happen because the dog eats food in a state of decomposition, ingests toxic substances ( poisons , medicines for humans, etc.), eats too much food, eats other animal feces or eats nondigestible substances (plastics, fabrics, toys, etc.). It also happens by internal parasites, bacterial or viral infection or by diseases of other organs such as the kidneys and liver.

If not treated properly, the acute form of the disease may develop for chronic gastritis . The latter is caused by the long-term damage of the gastric mucosa and the bacterial flora of the digestive tract. Some things ingested by the dog that are not digestible can remain in the stomach without traversing the entire digestive tract, causing irritation and inflammation. This is the case of plastics, pieces of carpets, paper, rubber toys and other elements that are frequently ingested by dogs.

Other causes of chronic canine gastritis are diseases. Bacterial infections, viral infections, distemper , parvovirus , cancer, kidney problems, liver diseases and food allergies can trigger gastritis in dogs. Persistent chemicals in the environment, such as fertilizers and pesticides, can also cause this form of the disease.

Gastritis affects dogs regardless of race or gender, but there is a risk factor in dog behavior and the irresponsible tendency of some owners. Dogs that eat from garbage, which roam freely through the streets and often eat the feces of other animals, are more likely to suffer from gastritis. Dogs that eat grass frequently are also prone, mainly by the presence of fertilizers and pesticides.


The initial diagnosis is made based on the clinical history and the symptoms that the dog presents. In addition, the veterinarian will want to know the animal’s eating habits, if he takes food from the litter, bites furniture and clothes, has access to places where poisons or medicines are stored, such as his normal diet and other diseases. treated. He will also examine the dog physically , observing inside the mouth and touching the neck, chest, belly and flanks.

To diagnose canine gastritis a blood test may be necessary to see if there are toxic or pathological conditions that have not been considered. In addition, x-rays and ultrasounds may be needed to see if there is any foreign body inside the stomach. When a chronic gastritis is suspected, the veterinarian may order a biopsy of the gastric mucosa.

Treatment for canine gastritis

The treatment of canine gastritis usually begins by withdrawing the animal from the foodfor a certain period of time, which can go from 12 to 48 hours. In some cases the veterinarian may also recommend limiting the amount of water without taking it off completely. In addition, the veterinarian will recommend a proper diet that usually has to be given in small and frequent rations until the gastritis has healed.

When necessary, your veterinarian will prescribe antibiotics, corticosteroids, antiemetics (to prevent vomiting) or other medications you deem appropriate for each case. If gastritis is caused by a foreign object in the stomach, the only solution is usually surgery.

Most cases of gastritis in dogs have a good prognosis after treatment. However, gastrites caused by cancer and other systemic diseases may have a less favorable prognosis.

Prevention of gastritis in dogs

As with most conditions, the best treatment is always prevention. And to prevent canine gastritis , in YourCatCareguide we recommend that you take into account the following advice:

  • Prevent the dog from stealing food from the bin.
  • Do not let the dog go out alone and wander around the neighborhood.
  • Prevent the dog from having access to toxic substances and medications.
  • Do not overeat.
  • Do not feed him leftovers (especially at parties), in addition to his normal food.
