Colitis is an inflammation of the large intestine or colon. Patients with colitis strain during defecation and have blood or mucus in the feces. Diagnosis is made based on the symptoms and your pet may also experience diarrhea, lethargy, loss of appetite, or weight loss. In case of the above-mentioned symptoms, you should immediately contact your vet. Causes of colitis include food allergy, parasitic infections, parasites, and food indiscrimination.

Your vet may also examine the feces of your pet for intestinal parasites. Fecal testing, blood work, and abdominal x-rays may be required to make a definitive diagnosis. Colitis may be acute or chronic. In the case of chronic colitis, the disease occurs frequently. Acute colitis may resolve itself while treatment for chronic colitis includes deworming treatment, antibiotics, and dietary modifications.
