What is going on when a dog has bloody diarrhea and vomiting, and what drugs can be used?

If the dog passes stool with a rotten tomato smell and shows abnormal symptoms such as lethargy and loss of appetite, it is recommended to visit the vet promptly.

The owner can take the dog to the hospital for an X-ray to determine the location of the bone.
