Inflammatory bowel disease in dogs: real veterinary cases
What vets used to call "IBD" in dogs is now better understood as a spectrum of "chronic enteropathies". Most cases turn out to be food-responsive (the dog resolves on a strict elimination diet), some are antibiotic-responsive, and a smaller fraction is true immune-mediated IBD that needs steroids or other immunosuppressants.
Because the categories overlap and only respond to treatment, vets work through them in order: rigorous diet trial first (8 weeks of hydrolyzed protein or strict novel protein), then antibiotic trial, then biopsy and steroids. Skipping the diet trial is the most common reason cases get "stuck" — many true food-responsive dogs end up on lifelong steroids that they didn't need.
What vets typically check for
- Rule out parasites (faecal float + Giardia), Addison's (ACTH-stim), and pancreatitis (cPL).
- Strict 8-week hydrolyzed-protein diet trial — no treats, no flavoured medications.
- If no response: antibiotic trial (metronidazole or tylosin) or proceed to biopsies.
- Endoscopic intestinal biopsies — confirms inflammation grade and rules out lymphoma.
- Treatment for true IBD: prednisone +/- chlorambucil or cyclosporine in refractory cases.

- Ménétrier-like disease in a dog without glandular atrophy: expanding the morphologic spectrum
BMC Veterinary Research · 2026
A 6-year-old male French Bulldog was brought in for severe weight loss and a sudden lack of appetite. Tests showed that he had thickened stomach walls and abnormal growths in his stomach lining, leading to a diagnosis of Ménétrier-like disease, a rare condition that causes protein loss. The owner chose not to pursue surgery or certain medications due to cost, so the vet started
- Emerging Concepts in the Understanding and Treatment of Canine Protein-Losing Enteropathy.
The Veterinary clinics of North America. Small animal practice · 2026 · United States
A dog with protein-losing enteropathy, a condition where the intestines lose too much protein, may show symptoms like weight loss, diarrhea, or poor coat condition. Treatment often includes glucocorticoids (steroids), but recent findings suggest that adjusting the dog's diet can lead to better results, especially for those not responding to steroids. Each dog's treatment should
- Pancreatic lymphangioma and concurrent intestinal lymphangiectasia in a dog.
Journal of veterinary internal medicine · 2026 · Japan
A 2-year-old Border Collie was brought in for watery diarrhea and weight loss. Tests showed low protein levels and imaging revealed a cyst near the pancreas along with signs of intestinal swelling. The dog initially improved with an anti-inflammatory medication, but symptoms returned. After surgery to remove the cyst and take biopsies, the dog was diagnosed with pancreatic lymp
- Ménétrier-like disease in a dog without glandular atrophy: expanding the morphologic spectrum.
BMC veterinary research · 2026 · Italy
A 6-year-old male French Bulldog was brought in for severe weight loss and loss of appetite. Tests showed thickening of the stomach and intestines, and a scope revealed abnormal growths in the stomach lining. The dog was diagnosed with a rare condition similar to Ménétrier's disease, which causes protein loss and stomach issues. Unfortunately, after starting treatment with ster
- Chronic inflammatory enteropathy without moderate to severe hypoalbuminemia: long-term outcome in 60 dogs.
Journal of veterinary internal medicine · 2026 · United Kingdom
A group of 78 dogs with chronic inflammatory enteropathy (CIE), a condition that affects their intestines, were studied to understand their long-term outcomes. The most common treatment that worked well was a special diet, which helped nearly 90% of the dogs improve without any gastrointestinal-related deaths. Other treatments were less effective, with some dogs experiencing mo
- Dogs with chronic enteropathy and low disease activity show signs consistent with compromised emotional health compared to matched healthy control dogs.
Journal of the American Veterinary Medical Association · 2026
A group of dogs with chronic enteropathy (a long-term gastrointestinal disease) showed signs of emotional distress compared to healthy dogs. The study found that these dogs had higher scores for negative emotions and displayed more signs of anxiety, especially when their owners were preparing to leave the house. This suggests that dogs with chronic gastrointestinal issues may a
Frequently asked questions
- How long does a diet trial really need to be?
- Eight weeks of strict adherence — no treats, no flavoured chews, no "just a tiny piece". Most owners give up at week 3-4 because the dog looks better, then re-introduce the old diet and the dog relapses. Many "failed diet trials" are actually shortened diet trials.
- What's the difference between IBD and lymphoma?
- Visually on endoscopy, they can look identical. The distinction is histopathological and sometimes immunohistochemical. It matters: IBD is managed, alimentary lymphoma is treated with chemotherapy. Always biopsy chronic GI cases before starting long-term steroids.
- Can probiotics help?
- There's growing evidence that high-quality canine-specific probiotics (e.g. those containing Enterococcus faecium SF68) can help as part of a multi-modal plan — but they're not a substitute for ruling out the underlying cause.
