What are Gastritis?

If your pet is suffering from excessive vomiting, consult your veterinarian. An examination may reveal that the gastric mucosa is inflamed. This may cause complications such as irritation, infection, ulceration, and blockage of gastric function. The secretion of gastric acid will be elevated as well. When the condition is severe, your dog may continue to vomit on a daily basis without relief, thus becoming a chronic condition due to the stomach becoming inflamed. 

An endoscopy will be one of the tests performed during the diagnostic process; the withholding of food and the administration of gastroprotectants may be required in order to cease the gastritis.

Gastritis is an acute or chronic syndrome that causes vomiting  and gastrointestinal inflammation. This may result in gastrointestinal upset that exhibits a wide range of symptoms.

Symptoms of Gastritis in Dogs

Most dogs that suffer from gastritis will experience extensive vomiting. The vomit may contain yellowish, foamy bile. This is especially true if the stomach is empty. Often, blood or food may be seen in the vomitus, particularly if your dog has partaken in consuming inappropriate foodstuffs. You might notice your pet gagging or breathing heavily after eating or drinking and your pet will have some tenderness around the stomach area when being picked up. Your dog will have no energy for movement and possibly a loss of appetite. Your dog may become dehydrated if persistent vomiting lasts more that 24 hours.

  • Vomit with blood, bile, food, or froth
  • Lethargy
  • Painful abdomen
  • Hunching of back in an attempt to ease abdominal discomfort


Gastritis can be classified as acute or chronic. Acute cases are often secondary to inflammation. Chronic gastritis may be seen with conditions such as allergy or parasitic infection.

Causes of Gastritis in Dogs

There are several possible reasons for the vomiting that your pet is experiencing. For that reason, your veterinarian will try to conduct different tests to rule out certain causes and conditions such as:

  • Tumors
  • Foreign bodies
  • Systemic infections
  • Poisoning
  • Pancreatitis
  • Parvovirus
  • Neoplasia
  • Dietary indiscretion

Diagnosis of Gastritis in Dogs

Gastritis has to be diagnosed through exclusion. Your veterinarian will seek to eliminate other conditions that show the same clinical symptoms prior to the final diagnosis. The initial step to determine the signs is to examine your pet’s medical history. From the dog’s medical history and information provided by you, the veterinarian will be able to assess specific things such as:

  • Existing diet such as how your dog is fed and the frequency
  • All the foods that your pet consumed within the last two days
  • All, if any dog treats eaten
  • Exposure to medications, pesticides or household cleaning agents
  • Exposure to a new dog in the household
  • Any serious illness within a period of one month or more
  • Any past episodes of diarrhea and vomiting
  • Any supplements taken within the last month

With the medical history and knowing more about your pet, the veterinarian will conduct a physical exam. Your veterinarian will be looking for any evidence of abdominal tenderness or pain, dehydration, gas, fever, bloating or swelling. Diagnostic tests will be done and these could include:

  • CBC or complete blood count to look for infection and dehydration
  • Urinalysis to detect urinary tract infection, diabetes, or kidney disease
  • Abdominal radiograph to look for anything abnormal in the stomach such as intestinal obstruction
  • Ultrasound or endoscopy to obtain a detailed view of the stomach

Treatment of Gastritis in Dogs

The first choice of treatment for gastritis is restoring the level of blood electrolytes and re-hydrating your pet. IV fluids will be administered in this case. Antibiotics will also be administered if there are severe clinical signs of infection observed. 

Prescribed medication (anti-emetics) will be given to counteract the vomiting. If your dog has a condition such as chronic colitis, the veterinarian may prescribe a motility agent to modify this condition.

Your veterinarian may withhold water and food during the first phase of treatment, after which these will be gradually reintroduced. In the interim, ice chips will be used to start the fluid intake orally. A mild diet fed to your dog in small quantities and frequently may be prescribed.

Recovery of Gastritis in Dogs

Most of the acute cases of gastritis will usually have a good prognosis after your pet has received adequate hydration. If there is no improvement within two days of receiving treatment, the veterinarian may want to reassess the situation. Chronic vomiting will cease with the elimination of the cause. Depending on your pet’s condition at time of evaluation, he may need to remain in the hospital until the veterinarian assesses him as stable enough to return home. Specific instructions will be given as to medications, if needed, and the reintroduction of food.

Famotodine 20mg

My dog has had gastritis in the past, and I had to take her to the vet for a severe episode a few months ago. She got into the garbage a few days ago, and it has triggered another reaction. Now that I know what it is, I fast her for 24 hours and have reintroduced a 1/3 boiled chicken and 2/3 white rice food. This is her second day eating it and she’s a lot more perky today with no vomit. She’s not needing to go the bathroom as frequently either, but I don’t know how much to give her and don’t want to give her too much or too little. How often and how much of the bland food should I give my 30lb Aussie mix?

Generally I recommend feeding a bland diet four times per day, reducing to three times per day after a day or two; after another day or two you can try to wean Lyric over to the regular dog food slowly and monitor for any gastrointestinal upset. Each dog is different and Lyric may require a slower approach. Regards Dr Callum Turner DVM

My dog vomits frequently, specially as soon as he finishes eating. He then eats a lot of grass and then vomits repeatedly. The vomit is chunky- the food hasn't had time to digest. Our vet said it's gastritis gave him some medicine and it worked for a short time, but as soon as the medication ended he started vomiting again. This has been going on for a couple of months now.We're really worried. Any help would be highly appreciated.

Thank you for your email. There can be many reasons for GI upset in dogs, including parasites, dietary indiscretion, food intolerance, or a foreign body. Since the treatment did help, it would be a good idea to follow up with your veterinarian, as they can examine him and determine what he needs a long term change to control these signs. I hope that everything goes well for him.

Vomiting blood

My 50 lb labradoodle ate 400mg of ibuprofen last night. I found out about 1 hour after ingestion, and when I called the Pet ER, the Vet suggested giving her hydrogen peroxide to induce vomiting. We did. After about an hour she vomited about 3 times which was primarily food, then it was more foamy bile. She acted fine after this and slept through the night. She vomited the next morning after eating breakfast. She has vomited a couple more times today but her behavior is normal. Now, her vomitus is bloody. She is drinking okay and behavior remains pretty normal. Is there something we should do to treat her for the ibuprofen ingestion? Is gastritis the worse result we should expect from this? What should we do to treat her gastritis? I read to withhold food for 24-48 hours. Any needed medications? Can dogs take zantac or prilosec or is there a pet version?

If Hollie ingested 400mg of ibuprofen I would recommend fluid therapy to be on the safe side and you can give famotidine at 0.25mg/lb twice per day. The effects of ibuprofen poisoning take a day or so to present with acute renal failure, whilst a 50lb dog should be in a good position size wise I would stay on the side of caution; the vomiting should pass but you should visit your regular Veterinarian for a once over especially if Hollie is vomiting blood.

Thank you for your email. It seems that Sparky's signs are deteriorating and he may be getting worse then when he was originally seen by your veterinarian. It would be a good idea to have a recheck for him, and have him re-evaluated to make sure there isn't more treatment that he needs, or lab work that might need to be done for him. I hope that he is okay.

Did Sparky get better? I'm doing research on different ailments in dogs since 2 vets are not getting him to fell better after 2 months. Still vomiting and feeling crappy. Was wondering how Sparky did on the pepcid??
