Seeing blood in a pet dog's stools is always alarming. Bloody stools can be a sign of serious illness. However, there are many less serious causes of blood in stools.

Bloody stools may be accompanied by mucus. As they are a symptom of a wide range of canine health conditions, it's important to have the dog assessed by a veterinarian as soon as possible to determine the cause and start any necessary treatment as soon as possible.


1. What Do Bloody Stools Look Like?

Bloody dog stools can vary in appearance depending on the cause. The stools may contain streaks of bright red blood. There may also be fresh, red blood dripping from the dog’s anus after they have had a bowel movement.

The blood may have a black appearance instead, changing the color of the dog's stools. This indicates that the blood has been digested.
