Diarrhea is a common digestive problem in dogs, and it can be caused by a variety of factors. When your dog has diarrhea for three or more days, it is important to identify the underlying cause and seek veterinary care if necessary. Possible causes of diarrhea in dogs include bacterial, viral, and parasitic infections, dietary changes or indiscretions, food allergies and intolerances, stress and anxiety, inflammatory bowel disease, pancreatitis, cancer, and kidney or liver disease.

Bacterial Infections in Dogs

Bacterial infections are a common cause of diarrhea in dogs, and they can be caused by a variety of bacteria, including Salmonella, E. coli, and Campylobacter. Dogs can contract bacterial infections from contaminated food or water, or from exposure to other infected animals. Symptoms of bacterial infections in dogs may include diarrhea, vomiting, loss of appetite, and lethargy. Treatment typically involves antibiotics and supportive care, such as fluid therapy and electrolyte replacement.

Prevention through vaccination is the best way to protect your dog from viral infections.
