Black, Tarry Feces Due to Presence of Blood in Dogs



The major goal of therapy is to address the underlying disease, which if successful, should ultimately resolve the melena. Fluid therapy may be given to replace deficit fluids in the body, and in patients with severe blood loss and anemia, a blood transfusion may also be required. Additional treatment will depend on a patient’s other symptoms and the underlying cause of the melena. For example, dogs with gastrointestinal ulcers may be treated with a change in diet and medications to reduce the secretion of gastric acid, protect the lining of the gastrointestinal tract, and limit vomiting (if necessary) while dogs who have ingested certain types of rodenticides will be treated with vitamin K.


Living and Management


The duration and type of treatment prescribed for your dog will depend on the underlying cause and the severity of the melena. Initially, frequent blood testing may be required to evaluate your dog for ongoing or worsening anemia, which may turn into more intermittent testing once your dog's health has stabilized. Watch your dog for the worsening of any of his clinical signs during treatment and talk to your veterinarian if you have any concerns.


Most patients will recover from melena as long as the underlying disease can be adequately addressed.
