Seeing blood in your dog’s stool can be a frightening experience.

While occasional bleeding can be non-specific and is probably not a cause for concern, frequent episodes of bleeding during defecation can be serious.

Medically known as melena or hematochezia, the blood in the dog’s stool can be dark colored and tarry, or fresh and bright red in color. 

Let’s look at the various causes of blood in a dog’s stool, and then at ways to remedy the situation.
