In order to stop a dog's diarrhea, it is best to temporarily withhold any food, but to still provide fresh, clean water to flush out the dog's system. Preventing diarrhea in the future requires monitoring what the dog eats and drinks and paying attention to any toys with which he plays.
When a dog's stool is loose, runny and off in color, it is characterized as diarrhea. There are many causes for dog diarrhea. Some of the more common causes could be stress, a change of diet or ingestion of a foreign object.
Much like with humans, diarrhea in dogs is a symptom of an upset stomach. If the dog's diet is a factor, it is important to gradually introduce any new food by mixing it in with the old food. Some of the more serious causes could be internal parasites, bacterial infection or an allergic reaction.
Consulting a veterinarian is always the best idea, especially when the diarrhea lasts more than a day. However, even the healthiest dog can get diarrhea, which is why it is so important to monitor what dogs put in their mouth. Anything from dirty water to spoiled food from the trash has the potential to upset a dog's stomach.
