An India-focused guide to canine gastritis covering sudden vomiting, chronic disease, dehydration, NSAID injury, ulcers, diagnostic imaging, gastroscopy and safe feeding.

Seek urgent veterinary care for

Repeated vomiting with inability to retain water
Blood, coffee-ground material or black stool
A swollen or painful abdomen
Collapse, weakness or pale gums
Suspected toxin, foreign object or human medicine exposure
An unvaccinated puppy with vomiting or diarrhoea

Acute versus chronic gastritis

Pattern	Typical timeline	Common concerns
Acute gastritis	Sudden signs lasting hours to a few days	Dietary indiscretion, toxin, medicine, infection or systemic illness
Chronic gastritis	Intermittent or persistent signs over weeks	Food-responsive disease, parasites, immune inflammation, tumour or systemic disease
Ulcerative disease	Vomiting with bleeding or anaemia	NSAIDs, liver disease, cancer, severe illness or steroid interaction

Common triggers and mimics

Food and scavenging

Garbage, spoiled leftovers, rich food, bones and abrupt diet changes can irritate the stomach or conceal a foreign body.

Medicines and toxins

NSAIDs, corticosteroid combinations, pesticides, plants and household chemicals may cause more than simple irritation.

Systemic disease

Kidney, liver, adrenal and pancreatic disease commonly produce vomiting.

Mechanical problems

Foreign objects, gastric outflow obstruction and bloat require urgent imaging or surgery.

How veterinarians investigate vomiting

History should include everything eaten, medicines, toxin access, vomiting frequency, stool, urination and whether the material was actively vomited or passively regurgitated.

Physical examination and hydration assessment
CBC, chemistry, electrolytes and urinalysis
Faecal and infectious testing where indicated
Abdominal radiographs or ultrasound
Pancreatic and adrenal testing when appropriate
Gastroscopy with biopsy for persistent disease

Important: Do not repeatedly label chronic vomiting as 'acidity'. Weight loss, blood, pain or recurring episodes require a structured work-up.

Treatment depends on cause and severity

Supportive care may include anti-nausea medication, fluid therapy, analgesia and a controlled digestible diet. Acid suppression is useful for selected ulcer or reflux situations but is not automatically needed for every vomiting dog.

Foreign bodies, severe ulcers, tumours and systemic diseases require cause-specific treatment. Antibiotics are not routine treatment for uncomplicated gastritis.

Feeding during recovery

Control vomiting first.
Offer small amounts of water when swallowing is normal.
Begin small frequent portions of a veterinary gastrointestinal diet.
Increase quantity gradually if tolerated.
Transition to the long-term diet over several days.

Chicken and rice can be used briefly when advised, but it is incomplete for prolonged feeding and unsuitable for dogs with chicken sensitivity.

India-specific risks

Spoiled food during summer or monsoon
Onion, garlic, masala and oily gravy in leftovers
Street scavenging and plastic ingestion
Unsupervised human painkillers
Contaminated water and infectious diarrhoea
Multiple family members feeding different remedies

Reducing recurrence

Secure waste, keep medicines locked, transition foods gradually and record every vomiting episode. Dogs with chronic disease may benefit from a consistent complete diet and planned rechecks rather than frequent home-food experiments.

Dogsvilla practical tip: At boarding, document vomit appearance, frequency, meal timing, water intake and abdominal pain. One accurate incident record can prevent hours of diagnostic guesswork.
