Inflammatory bowel disease is the invasion of inflammatory cells into the stomach and intestines. IBD can be of unknown cause (i.e., idiopathic), or triggered by parasites, bacterial infection, dietary intolerance, genetic factors, and abnormal immune response to bacterial antigens. IBD is a “diagnosis of exclusion,” meaning underlying conditions have been ruled out.

IBD treatment has many approaches, with testing and treatment for parasites the first step. Changing to a high fiber or low-antigenic prescription diet can resolve many IBD cases in dogs. Certain probiotics, used alone or in combination with a food trial, have shown promising results. Antibiotics can decrease intestinal bacteria, and the body’s inflammatory response to bacterial antigens. Immunosuppressive medications (e.g., steroids or other therapies) are needed if treatment response is poor. Adding B vitamins, or anti-nausea or anti-diarrheal medication, is often helpful. Dogs with IBD need regular veterinary visits and diagnostic monitoring, and discussing a personalized management plan with your veterinarian is important for the best outcome for your dog.
With appropriate treatment, most dogs with IBD can live healthy, comfortable lives. Some dogs have a good response after a few months of treatment, or may go in and out of remission from the disease. Many dogs require a specialized diet or lifelong therapy. Dogs who are refractory to treatment, have an underlying disease, or develop stomach or intestinal cancer have a poorer prognosis.
Contact your veterinarian immediately if your dog stops eating; has uncontrollable diarrhea or vomiting, a distended abdomen, or difficulty breathing; or vocalizes in pain.
Before your dog‘s condition becomes unmanageable, or they begin losing their quality of life, beginning end-of-life care discussions is vital.
