Gastric Stasis is very common in rabbits, but it can also occur in Dogs. When the stomach is interrupted in its normal operation, a condition called stasis can result. Stasis is when the stomach slows its contractions, and may even stop working altogether.

The most common symptoms of gastritis include:

  • Excessive vomiting
  • Decreased appetite
  • Dehydration
  • Increased thirst
  • Lethargy
  • Depression
  • Diarrhea
  • Blood in stool or vomit
  • Black, tarry stools
  • Abdominal pain

Dogs are particularly prone to dietary indiscretion which includes the ingestion of spoiled food, non-food items such as garbage, cat-litter, foreign objects, plants, toxins, molds and fungi (mushrooms), feeding inappropriate foodstuffs such as table scraps or leftovers, or being fed large quantities of food or a diet change.

With acute gastritis, most dogs recover in one to three days with supportive treatment, which includes a short period of withholding food. The prognosis is usually good, even if the primary cause is not identified. Some of the common causes or conditions associated with gastritis in dogs include:

Antibiotics Fungal infection Liver Disease Anti-inflammatories (NSAIDs) Fungal toxins Mast cell tumor Bacterial infection Gastrinoma or other neoplasia Molds Chemical irritants Granulomatous gastric disease Overeating Chemotherapy Heavy metal poisoning Pancreatitis Corticosteroids Hypoadrenocorticism (Addison's disease) Poisonous plants Diabetic ketoacidosis Idiopathic (unknown cause) gastritis Spoiled food Dietary indiscretion Immune mediated disease Stress Endocrine disease Inflammatory bowel disease Toxins Food allergy Intestinal parasites Uterine infections Foreign body Kidney disease Viral infections.

Tests for gastritis may include blood tests, urinalysis, fecal tests, abdominal X-rays, abdominal ultrasound, and endoscopy. In acute cases, only minimal diagnostics such as blood and urine tests are required.

Medical treatment for dogs with gastritis may include:

  • anti-emetic (anti-vomiting) medications, for example maropitant (brand name Cerenia®) or metoclopramide (brand name Reglan®)
  • fluid therapy if patient is dehydrated
  • proton pump inhibitors – can be used in severe cases of stomach ulceration, for example omeprazole
