My dog has been showing signs that might involve vomiting diarrhea gastrointestinal. What conditions should I research?
A pet owner asked our search engine this exact question. We pulled 20 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 The cases primarily involve gastrointestinal issues in dogs, particularly conditions like gastritis (stomach inflammation), pancreatitis (inflammation of the pancreas), and acute hemorrhagic diarrhea syndrome. Symptoms commonly include vomiting, diarrhea, abdominal pain, and dehydration. ## Treatments that worked - **Supportive care**: This included fluid therapy and nutritional support, which was effective in 5 of 8 cases with gastrointestinal issues. - **Surgery**: Surgical intervention was necessary in cases involving foreign bodies or severe complications, showing success in 3 of 4 cases where surgery was performed. - **Antibiotics**: Used in cases of infections like Giardia, antibiotics helped improve symptoms in 4 of 6 relevant cases. ## Outcomes The treatments mentioned above had varying success rates, with supportive care being the most consistently effective approach across multiple cases, while surgical interventions were critical in specific severe cases. ## 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.
Pancreatitis
Pancreatitis is inflammation of the pancreas, often causing vomiting, diarrhea, and abdominal pain in dogs. It can be triggered by a high-fat diet or certain medications. Diagnosis typically involves blood tests and abdominal ultrasound.
Inflammatory bowel disease (IBD)
IBD is a chronic condition where the intestines become inflamed, leading to symptoms like vomiting and diarrhea. It's often diagnosed through a combination of blood tests, imaging, and sometimes intestinal biopsies.
Gastric foreign body
A gastric foreign body occurs when a dog ingests an object that cannot pass through the gastrointestinal tract, causing vomiting and sometimes diarrhea. X-rays or ultrasound are typically used to diagnose this condition.
Dietary indiscretion
Dietary indiscretion refers to a dog eating something unusual or inappropriate, leading to gastrointestinal upset like vomiting and diarrhea. This is often diagnosed based on history and clinical signs.
Addison's disease (hypoadrenocorticism)
Addison's disease is a hormonal disorder where the adrenal glands do not produce enough hormones, leading to symptoms like vomiting, diarrhea, and lethargy. Blood tests, including an ACTH stimulation test, are used for diagnosis.
Parvovirus
Parvovirus is a highly contagious viral infection that causes severe vomiting and diarrhea, especially in puppies. Diagnosis is typically confirmed with a fecal test for the virus.
Easily confused with: Gastric ulcer · Exocrine pancreatic insufficiency · Intestinal parasites · Hemorrhagic gastroenteritis

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.

Duodenogastric intussusception with concurrent gastric foreign body in a dog: a case report and literature review.Journal of the American Animal Hospital Association · 2013 · United States
A 3-year-old spayed female boxer, weighing about 50 pounds, was brought to the vet because she was vomiting a lot and seemed to be straining to have a bowel movement. During the examination, the vet noticed her heart was racing, she was breathing fast, she was dehydrated, and her belly was painful. X-rays revealed a golf ball stuck in her stomach and a large mass in the area where the stomach connects to the intestine. Attempts to remove the golf ball using a camera were unsuccessful, and surgery was needed to properly diagnose and treat the condition, which involved parts of her stomach and intestine folding into each other. After surgery, where the foreign object was removed and steps were taken to prevent future issues, she was able to go home about a day and a half later and was doing well at her follow-up a year later.

Acute hemorrhagic diarrhea syndrome associated with contaminated foreign bodies (used feminine hygiene products) in a Golden Retriever dog.The Journal of veterinary medical science · 2018 · South Korea
A one-year-old male Golden Retriever was brought to the vet after suddenly starting to vomit and having bloody diarrhea for two days. He seemed very tired and was in pain, showing signs of dehydration and a fast heartbeat. X-rays showed that his entire digestive system was swollen and filled with fluid, and a foreign object was found in his stomach area, but it wasn't blocking anything. After some initial treatment, he started to get better, but by the fourth day, he stopped eating and began vomiting again. Further imaging showed a serious complication in his intestines, and surgery revealed that the foreign object was actually two used feminine hygiene products, which likely caused his initial illness and later complications.

Small animal reviewCompanion Animal · 2023 · United States
Pancreatitis is a serious and common illness in dogs that affects the pancreas, which helps with digestion and regulating blood sugar. Dogs with chronic pancreatitis may have repeated episodes of stomach pain and stop eating, while those with acute pancreatitis often experience vomiting. In the most severe cases, this condition can lead to shock and even death. Because the pancreas has several important functions, pancreatitis can cause significant problems with the body's metabolism. It's crucial to address this condition promptly to avoid serious complications.

Case Report: Multiple Tick-Borne Diseases and Gastrointestinal Protozoal Infection in a Young Poodle DogMedia Kedokteran Hewan · 2025 · ID
A three-month-old female poodle was diagnosed with multiple infections caused by ticks and gastrointestinal parasites. The owner noticed that the dog was vomiting yellow fluid, had bloody diarrhea, and had stopped eating. During the vet's examination, the dog was found to be very tired, slightly dehydrated, and had swollen lymph nodes, along with a tick on her body. Tests showed positive results for several tick-borne diseases and the presence of Giardia and Amoeba in her stool. After receiving a combination of antibiotics, fluids, vitamins, and special food, the dog showed significant improvement during a three-day hospital stay and was considered fully recovered after two weeks of treatment.
