Here's why:
* Chronic diarrhea can be a symptom of a serious underlying medical condition. This could include infections, parasites, food intolerances, inflammatory bowel disease, or even cancer.
* Prolonged diarrhea can lead to dehydration and malnutrition. Puppies are particularly vulnerable to these complications.
* Milk is not a suitable food for puppies. They are lactose intolerant and milk can actually worsen diarrhea.
Please don't wait any longer to get your puppy to the vet. They can run tests to determine the cause of the diarrhea and provide the appropriate treatment.
