Inflammatory bowel disease (IBD)
Do you have a dog with suspected or diagnosed IBD?
IBD in dogs
IBD is a collective term for chronic inflammation of the gastrointestinal tract in dogs. The condition can affect both the small intestine and the large intestine, and may cause a range of symptoms such as diarrhea, vomiting, and weight loss. When the inflammation is localized to the large intestine, it is often referred to as colitis. The intestinal lining (GI mucosa) acts as a barrier between the body and the external environment and is home to the majority of the body’s immune cells. These cells protect the dog from harmful bacteria and foreign substances—but in IBD, they become overactive, leading to chronic inflammation.
Risk factors
- Food antigens (substances in food that the immune system interprets as harmful) - Pathogenic bacteria or parasites - Dysbiosis – an imbalance in the intestinal microbiota - Impaired intestinal cell health - Genetic predisposition – breeds such as German Shepherds and Boxers are more susceptible When these triggers activate the immune system, inflammatory mediators (eicosanoids) are produced, leading to persistent irritation and damage to the intestinal lining.
Symptoms
**Common symptoms in dogs with IBD:** - Frequent bowel movements - Bloody or mucus-covered diarrhea - Tenesmus – a persistent urge to defecate despite an empty bowel - Vomiting - Reduced appetite - Weight loss Symptoms vary depending on which part of the intestine is affected—vomiting is more commonly seen when inflammation involves the small intestine.
Treatment
A successful approach to IBD often involves multiple measures: **1. Identifying and eliminating the underlying trigger** Whenever possible, the goal is to identify and remove the underlying cause, such as an infection or a reaction to specific ingredients in the diet (e.g. an elimination diet) **2. Reducing inflammation** This is often achieved using medications such as: - Corticosteroids (e.g., prednisone/prednisolone) - Sulfasalazine (in cases of colitis) These medications have both anti-inflammatory and immunosuppressive effects. **3. Optimizing the diet** A gentle, tailored diet can help reduce inflammation, improve nutrient absorption, and enhance overall quality of life.
IBD and home made diets – evidence from studies
A prospective observational cohort study (2024) followed 167 dogs for 14 months after the introduction of an individually tailored home-prepared diet (Pignataro et al., 2024). Of these dogs, 67 had pre-existing health conditions, primarily related to gastrointestinal and skin disorders. Among dogs diagnosed with chronic intestinal disease (commonly referred to as chronic enteropathy), owners reported the following outcomes: - Approximately **95%** showed improvement in clinical symptoms - **Over 90%** of all dogs classified as “ill” demonstrated overall health improvement - Many experienced near-complete remission of clinical signs Positive effects were also observed among the 31 healthy dogs maintained on a long-term maintenance diet: - **70%** showed improved coat quality - **47%** experienced reduced stool frequency - Stool consistency, appetite, and energy levels remained stable throughout the study period (Pignataro et al., 2024) In addition, a clinical case published in *Veterinary Record Case Reports* (2023) described a Boston Terrier with chronic pancreatitis and suspected inflammatory bowel disease (IBD) that failed to respond adequately to both medical therapy and commer…
What this means for dog owners
These findings suggest that a carefully planned home-prepared diet can be a valuable part of managing chronic gastrointestinal disease, including IBD, in dogs. For some dogs, especially those that do not respond adequately to medication or commercial therapeutic diets, dietary intervention alone may lead to significant clinical improvement. While a home-prepared diet is not a replacement for veterinary care, it can be a powerful complementary strategy that improves symptoms, quality of life, and long-term outcomes.
Diet characteristics
Choosing the right diet is central to managing IBD. This often includes: - Limiting dietary triggers, such as specific protein sources or additives - High-quality protein sources - Low fiber content and high digestibility - Anti-inflammatory supplements, such as omega-3 fatty acids and antioxidants - Gluten-free carbohydrate sources, as gluten may be problematic for some dogs with IBD - Low fat content, since fat can worsen symptoms in sensitive dogs
IBD-supportive diets for sensitive dogs
Our carefully formulated diets designed specifically for dogs with IBD, feature low fat, low fiber, and highly digestible ingredients to support gut health and reduce inflammation. See tags in top of this article
