If your dog is experiencing diarrhea, it's important to determine the cause in order to provide the appropriate treatment. In some cases, simple dietary changes or deworming may be sufficient, while other conditions may require medical treatment such as antibiotics, antiparasitic medication, or specialized diets. If diarrhea persists for more than 24 hours or is accompanied by other concerning symptoms, it's best to consult a veterinarian for proper diagnosis and treatment.
