Diarrhea in dogs can manifest in different forms, from soft stools to more severe watery feces. It is often accompanied by other symptoms such as vomiting, lethargy, and loss of appetite. Before jumping into treatment options, it's crucial to identify the cause of your dog's diarrhea. If your dog has had any changes in diet, exposure to new environments, or contact with other animals, these might provide clues to the underlying issue.
