An India-focused guide to canine chronic inflammatory enteropathy covering chronic diarrhoea, vomiting, diet trials, protein loss, ultrasound, biopsy and immunosuppressive treatment.

Seek urgent care when chronic gut signs become unstable

The dog cannot keep water down or is severely dehydrated
There is collapse, profound weakness or very pale gums
The abdomen becomes painful or distended
Stool is black, heavily bloody or accompanied by repeated vomiting
Rapid weight loss, swelling of the legs or abdominal fluid develops
A puppy, senior or medically fragile dog stops eating

Why the terminology has changed

The 2026 ACVIM-endorsed consensus describes chronic inflammatory enteropathy as persistent or recurrent gastrointestinal disease in which inflammation is suspected or confirmed after appropriate evaluation. The term is broader and more useful than automatically labelling every chronic diarrhoea case as inflammatory bowel disease.

Dogs may be diet-responsive, immunosuppressant-responsive, microbiota-modulation-responsive or difficult to classify. The response category is discovered through a structured therapeutic sequence rather than a single commercial blood test.

Common clinical patterns

Small-intestinal pattern

Large-volume diarrhoea
Weight loss
Poor body condition
Dark stool in some cases

Large-intestinal pattern

Frequent small stools
Urgency
Mucus
Fresh red blood

Upper-gut signs

Vomiting
Nausea
Reduced appetite
Lip licking or grass eating

Protein-losing disease

Low albumin may lead to fluid in the abdomen, swelling, muscle loss and greater clotting risk.

Conditions that must be excluded first

Alternative cause	How it overlaps	Useful evaluation
Parasites and protozoa	Diarrhoea, mucus, weight loss	Faecal tests and appropriate parasite control
Exocrine pancreatic insufficiency	Weight loss with large stools and hunger	Fasting serum TLI
Addison's disease	Intermittent vomiting, diarrhoea and weakness	Electrolytes and adrenal testing
Liver, kidney or pancreatic disease	Poor appetite, vomiting and weight change	Blood, urine and imaging
Foreign body or tumour	Chronic vomiting, pain or weight loss	Ultrasound, endoscopy or surgery

In India, scavenging, repeated diet changes, unregulated supplements, contaminated water and empirical antibiotic use can complicate the history. Every food, dewormer, medicine and supplement should be listed accurately.

A stepwise diagnostic plan

Document the pattern. Record duration, stool character, vomiting, appetite, weight and response to previous diets.
Perform minimum database testing. Blood count, chemistry, urine and faecal evaluation help identify mimics and severity.
Measure key nutrients and proteins. Albumin, cobalamin and folate may influence urgency and treatment.
Use abdominal ultrasound selectively. It evaluates intestinal layers, lymph nodes, pancreas, liver and free fluid.
Complete a strict diet trial. This is a diagnostic intervention, not merely a food preference test.
Consider endoscopy and biopsy. Tissue is valuable when disease is severe, atypical or unresponsive.

Diet trials are central—not an optional extra

A veterinary diet trial may use a hydrolysed protein, a truly novel protein, a highly digestible formulation or a fibre-modified diet depending on the pattern. No single diet suits every dog.

Feed only the selected diet and approved water
Stop table scraps, biscuits, chews and flavoured supplements
Check flavoured medicines and toothpaste
Prevent scavenging and shared-bowl access
Keep a daily stool and vomiting record
Continue for the full prescribed period before judging failure

Important: Switching between chicken-rice, curd, paneer, khichdi and several commercial foods every few days prevents a valid diet trial and may create further digestive instability.

Treatment after the diet phase

Dogs that improve on diet may remain on the effective complete formulation and later undergo a controlled challenge if confirmation is needed. Dogs with persistent inflammatory disease may require glucocorticoids or another immunosuppressive medicine after infectious and dietary causes have been addressed.

Cobalamin deficiency is corrected when present. Selected dogs may receive microbiota-directed treatment or faecal microbiota transplantation through specialist protocols, but routine antibiotics are increasingly discouraged.

Protein-losing enteropathy

Low albumin changes urgency and prognosis. Additional testing excludes urinary protein loss and reduced liver production. Dogs may need clot-risk assessment, careful nutrition, more intensive immunosuppression and closer monitoring.

Swollen limbs, abdominal fluid, breathing change or sudden weakness can indicate complications and should not wait for a routine appointment.

Measuring whether treatment works

Weekly body weight during active disease
Stool frequency and consistency
Vomiting and appetite
Body and muscle condition
Albumin, cobalamin and inflammatory markers when indicated
Medicine adverse effects and infection signs

Dogsvilla practical tip: For boarding a dog on a diagnostic diet trial, send sealed pre-portioned meals and a written zero-extras rule. One flavoured treat can invalidate weeks of careful observation.
