Diarrhea seems to be a mild health problem but could threaten your dog's life if not treated immediately...
A healthy Labrador Retriever will normally defecate firm stools once or twice a day. However, if your Labrador Retriever passes semi-solid or liquid stools more often than usual, then he is probably suffering from canine diarrhea. Diarrhea is common in Labrador Retrievers because of their hearty appetites. They tend to eat anything, digestible and non-food objects alike, especially if their owners are not looking. With immediate attention and proper care, diarrhea caused by ingesting foreign objects can be treated within a day or two.
