why do dogs get diarrhea

Dogs get diarrhea for a variety of reasons, ranging from mild to serious. Common causes include eating garbage or spoiled food, sudden changes in diet, ingestion of toxins or foreign objects, stress or anxiety, and infections from parasites (like giardia or roundworms), bacteria, or viruses. Other causes can be underlying health conditions like pancreatitis, inflammatory bowel disease, liver or kidney disease, allergies, medication side effects, and even cancer affecting the digestive system. Stressful events can also trigger diarrhea in dogs. In summary, dogs get diarrhea mainly due to digestive upset caused by diet changes, ingestion of inappropriate substances, infections, internal parasites, health disorders, or stress.
