Melena in dogs.

The term used to describe the filth melena stool black, sticky which arises because of the blood in the intestine or internal bleeding through the intestines. 

Melena is generally caused by bleeding in the upper gastrointestinal tract. The disease also occurs in dogs after they ingest large amounts of blood from the oral cavity or respiratory tract. Melena is not a disease, but a symptom caused by another disease. The dark color of the blood due to a compound of iron contained in the hemoglobin (the oxygen-carrying red blood cells) through the small intestine and colon. 

Symptoms and Types 

Symptoms related to the cause and location of the bleeding. 

In patients with gastrointestinal bleeding: 

Vomit that contains blood 

Loss of appetite 

Losing weight 

weak 

Pale mucous membranes 

Anemia (anemia) 

In patients with bleeding in the respiratory tract: 

nosebleed 

Sneezing 

coughing up blood 

Pale mucous membranes 

Anemia (anemia) 

weak 

difficulty in breathing 

In patients with abnormalities / blood clotting disorders 

nosebleed 

The presence of blood in urine 

The presence of blood in the eye (hyphema) 

Anemia (anemia) 

Pale mucous membranes 

weak 

cause 

The presence of ulcers or ulcers of the gastrointestinal system 

Tumors of the esophagus or stomach 

infection 

The presence of a foreign body in the gastrointestinal system 

Abnormalities that result in inflammation of the intestinal system 

kidney failure 

Toxicity of drugs (eg. Anti-freeze) 

Diet consisting of raw meat 

pneumonia 

trauma 

Abnormalities that result in abnormal blood clotting 

diagnosis 

You need to give your dog's health history thoroughly, beginning of symptoms, and possibly related to the current conditions. The history you provide vet can tell you a clue on where the blood came from. Having received all the medical history, your veterinarian will perform a complete physical exam. Standardization of laboratory tests include the calculation of the amount of blood (Complete Blood Count; CBC), biochemical profile (Biochemistry Profile) and urine analysis. The results of these tests will depend on the main cause of this problem. 

Blood tests will show anemia where red blood cells are smaller and paler than normal (hypochromic). In the case of blood loss, anemia generally do not regenerate, the meaning behind the bone marrow does not respond as usual as the body increases the demand for red blood cells. In acute cases, anemia is usually regenerate, as the spinal marrow respond normally to the body's demand for the supply of new red blood cells. 

Other abnormalities may include a lack of platelets (cells responsible for blood clot), the addition of white blood cells which are usually called neutophils (neutrophilia), and the lack of numbers on the number of red blood cells and white blood cells. Biochemical profile will indicate changes to cause melena apart from bowel disease, including kidney and liver. Analysis of urine can indicate the presence of blood in the urine, which is often found in patients with abnormalities of blood clotting. 

Abdominal X-ray is always performed for the presence of clusters, foreign objects that may be swallowed, and abnormalities in the size and shape of the kidneys or liver. X-rays of the chest (thoracic) can help identify lesions of the lungs and the esophagus, which is also a major cause of the melena. 

Ultrasound (ultrasound) are also used to view the inside and often show a clearer picture of the state of the abdominal cavity and gastrointestinal tract. Ultrasound may show liver disease, inflammation of the pancreas, or kidney disease. Another diagnostic tool that can be used by your veterinarian is an endoscopy, an elastic tube that is inserted into the stomach through the esophagus to look directly ulcers in the esophagus, stomach and intestines. Endoscopy also helps in taking biopsy samples to analyze the network and remove foreign objects if there is a foreign object inside.
