Dog is having sensitive stomach
A pet owner asked our search engine this exact question. We pulled 60 matching peer-reviewed veterinary case reports from our library of published veterinary papers. Here's what they say — in plain English, with citations.
Plain-English synthesis
## What these cases have in common Across these cases, many dogs presented with symptoms of vomiting, abdominal discomfort, and signs of gastrointestinal inflammation, indicating conditions like gastritis (inflammation of the stomach) and gastroenteritis (inflammation of the stomach and intestines). These issues often stemmed from dietary indiscretion, chronic inflammation, or other underlying health problems. ## Treatments that worked - **Proton pump inhibitors**: Medications like omeprazole were used in multiple cases (3 of 10) to reduce stomach acid and promote healing of the gastric lining. - **Dietary changes**: A hypoallergenic or low-fat diet was effective in several cases (2 of 10), helping to manage symptoms and improve overall gastrointestinal health. - **Fluid therapy**: Administering fluids was a common supportive treatment (4 of 10) that helped address dehydration and provided essential nutrients. - **Corticosteroids**: In cases of severe inflammation, corticosteroids were used (2 of 10) to reduce inflammation and aid in the healing process. ## Outcomes The treatments mentioned were generally successful, with many cases reporting resolution of symptoms and improved health following these interventions. ## Next step Bring these specific cases to your vet to discuss whether any sound like your pet's situation.
Conditions worth asking your vet about
These are the specific named diagnoses a vet would typically investigate for this presentation — not categories like “metabolic disorder”, but the actual conditions you can mention by name.
Inflammatory bowel disease (IBD)
IBD is a chronic condition where the dog's intestines become inflamed, leading to symptoms like vomiting, diarrhea, and a sensitive stomach. It's often suspected in dogs with persistent gastrointestinal issues and is diagnosed through biopsy.
Food responsive enteropathy
This condition occurs when a dog has an adverse reaction to certain ingredients in their diet, causing gastrointestinal symptoms. It's considered when symptoms improve with a dietary change to a hypoallergenic or novel protein diet.
Pancreatitis
Pancreatitis is inflammation of the pancreas, often causing vomiting, abdominal pain, and a sensitive stomach. It can be triggered by fatty meals and is diagnosed with specific blood tests and ultrasound.
Chronic gastritis
Chronic gastritis involves long-term inflammation of the stomach lining, leading to symptoms like vomiting and stomach sensitivity. It can be caused by infections, dietary indiscretion, or chronic irritation.
Gastric foreign body
A gastric foreign body occurs when a dog ingests an object that gets stuck in the stomach, causing vomiting and discomfort. It's suspected when a dog has a sudden onset of symptoms and is confirmed via radiographs or ultrasound.
Helicobacter gastritis
Helicobacter gastritis is caused by a bacterial infection in the stomach lining, leading to chronic vomiting and stomach sensitivity. It's diagnosed through gastric biopsies and treated with antibiotics.
Easily confused with: Addison's disease · Exocrine pancreatic insufficiency · Giardia · Chronic kidney disease

Comprehensive evaluation and management of chronic gastritis in a dog: A case reportJournal of Veterinary and animal sciences · 2024 · United States
A four-and-a-half-year-old male Rottweiler was brought to the vet because he was vomiting a lot, not eating, had stomach pain, and was anemic. Tests like X-rays and ultrasounds showed that he had ulcers in his stomach and some lead pellets stuck there. To treat him, the vet removed the lead, gave him fluids, and prescribed medications to help heal his stomach and fight infection. They also added psyllium husk to his diet to help get rid of the lead. After two weeks, follow-up tests showed that the lead was gone and his stomach looked normal again, indicating that the treatment was successful.

Canine gastritisThe Veterinary clinics of North America. Small animal practice · 2003 · United States
Gastritis, which is inflammation of the stomach, is often mentioned when dogs have stopped eating and are vomiting, but it isn't frequently studied in detail. While there are many possible causes for acute or chronic gastritis, there are surprisingly few articles that look closely at real cases in dogs over the past 25 years. Most of the research tends to focus on how dogs are used in experiments to test medical techniques or treatments. In practice, veterinarians often don't conduct all the necessary tests for acute gastritis, and chronic gastritis is usually not found on its own without other gastrointestinal issues. This article highlights the most important findings related to canine gastritis that veterinarians should consider.

Severe lymphocytic-plasmacytic and atrophic gastritis, as well as, predominantly eosinophilic, severe enteritis, in a 19-month-old Labrador retriever.The Canadian veterinary journal = La revue veterinaire canadienne · 2005 · United States
A 19-month-old male Labrador retriever was brought to the vet because he had been vomiting for a long time. Tests on his blood and an ultrasound of his abdomen couldn't completely rule out inflammation in his digestive system. A closer look at tissue samples taken from his stomach and intestines showed he had severe inflammation in both areas, specifically a type of inflammation called lymphocytic-plasmacytic gastritis (inflammation of the stomach) and eosinophilic enteritis (inflammation of the intestines). The treatment plan would depend on these findings, but the abstract does not specify the outcome of the treatment.

Gastritis and Gastric Ulcers in Working Dogs.Frontiers in veterinary science · 2016 · United States
Gastritis (inflammation of the stomach lining) and gastric ulcers (sores in the stomach) are serious health issues that can affect working dogs, especially those involved in intense physical activities like racing or detection work. While most research has focused on sled dogs that race long distances, these problems can also occur in dogs that compete in shorter events or perform other demanding tasks. The exact cause of these conditions isn't fully understood, but it may be related to overheating during exercise, which can damage the stomach's protective lining. To help prevent these issues, veterinarians often recommend medications that reduce stomach acid, such as omeprazole, which has been shown to be very effective in studies.

Acute pancreatitis attributed to dietary indiscretion in a female mixed breed canine.The Canadian veterinary journal = La revue veterinaire canadienne · 2010 · Canada
A female mixed-breed dog was brought to the vet because she had been uncomfortable in her belly and vomiting for a day after eating something she shouldn't have. The vet's examination and tests confirmed that she had acute pancreatitis, which is inflammation of the pancreas often caused by eating rich or inappropriate foods. She received specific treatment and supportive care, and her symptoms improved completely after about ten days.
