The color of blood
In medical terms the presence of blood in the stool can be of two types: hematoquezia or melena , and can be distinguished by the color of blood . It is important to distinguish these two types of blood in the stool because it conditions the diagnosis.
- The hematochezia is the presence of fresh blood in the stool This blood has a vivid red color in the faeces. In this case the blood has not been digested, it comes from the lower digestive system, usually the colon or the rectum. In hematochezia the blood may be mixed with faeces or you may notice drops of blood drop when your dog evacuates.
- The mane is the presence of blood digested in the stool: the blood has a dark, foul-smelling color and generally looks like tar. This blood has been digested and comes from the upper portions of the digestive system.
