Dog Bloody Diarrhea
" Dog bloody diarrhea may be caused by two forms of diarrheal disease. . Both of them are related to intestinal abnormalities, in the small or large intestine. Fresh blood with more fluid indicates a problem in the large intestine, while a black and tarry soft stool indicates small intestine involvement. Differentiation between the two forms may help in treating dog bloody diarrhea. Common causes of bloody canine diarrhea are hemorrhagic gastroenteritis and canine parvovirus disease. The least common caused is gastrointestinal neoplasia which is a tumor or uncontrolled cell growth. Other accompanying symptoms include dehydration, lethargy, loss of body condition, anemia and hypovolemic shock. Diagnosis is usually based upon the clinical examination of the affected dog, and stool examination in lab. Treatment involves elimination of the underlying cause, fluid therapy and management of the condition. "
Causes of Dog Bloody Diarrhea:
- Hemorrhagic
Gastroenteritis; This condition will appear as
if there was a sudden onset of bloody diarrhea in dogs. Young
dogs and toy
breeds are more susceptible. The exact cause of hemorrhagic
gastroenteritis is unknown. Nutritional disorders and some species of
bacteria like Clostridium perforingens & E. coli are suspected
as causative factors.
In most of the researched cases, permeability of vascular & lumen gut tubes are reportedly increased, which possibly causes a leakage of blood in to the intestine. This condition is associated with hyperactivity and stress factors. - Canine
Parvovirus Disease; Canine Parvovirus CPV – Type 2
is known for causing dog bloody diarrhea. This is a contagious diseases
transmitted to a population of dogs via contact, in the air or via the
ingestion of fecal contents which contain virus particles. Recovered
dogs still act as carriers for the virus.
Along with other generalized signs, bloody diarrhea is associated with enteritis (inflammation in the intestine). Feces appears loose containing blood mixed with mucus. - Gastrointestinal Neoplasia; Amongst the causative factors for bloody diarrhea in dogs, gastrointestinal neoplasia (tumor or uncontrolled cell growth) is considered to be uncommon. Less then 1% of all dogs develop this kind of neoplasia. This may be because of few cases are diagnosed as being neoplasia, although it was the underlying cause of the canine diarrhea. Adinocarcinomas (cancerous tumor) in the gastrointestinal tract is the cause in this type of bloody diarrhea.
Signs and Symptoms of Dog Bloody Diarrhea:
There are two forms of bloody diarrhea in dogs, as defined by the cause, in the large or small intestine. Any deformity in the large intestine may cause diarrhea. The diarrhea will appear to have a significant amount of of fluid and the blood will appear bright red from fresh blood. An affected dog defecates frequently with low volume of fluid. Such a condition may also be called hematochezia.
Dog bloody diarrhea, due to any problem in the small intestine is represented by tarry, black stools. When a dog with a small intestine problem defecates, there will be a large volume of fluid. Another name for this type of canine diarrhea is melena.
Anemia (low red blood cell count) and dehydration are the two main symptoms correlated with canine bloody diarrhea. Dehydration, hypovolemic shock (sudden drop in blood pressure) and death in puppies are usually caused by the anemia and dehydration.
Diagnosis of Dog Bloody Diarrhea:
Determining the cause of the condition and whether the problem is in the small or large intestine is very important, as it may describe the involvement of different causative factors. Examination of the stool in the lab may help in isolating any bacteria or virus as the cause. Total Blood Count (TBC) may help in describing the degree of the anemia.
Dog bloody diarrhea due to canine parvovirus may be confirmed by different tests such as ELISA and the haemagglutination tests.
Treatment:
Three different approaches should be followed to treat dog bloody diarrhea, treating the cause, supportive therapy and management.
Elimination of the underlying cause is important. If it is a Virus, such as canine parvovirus, can never be specifically treated, but supportive fluid therapy and the use of broad spectrum antibiotics will help in controlling further complications.
Similarly, hemorrhagic gastroenteritis should be diagnosed for its possible cause. First the dog will be checked for anemia and hydration prior to the use of anti-biotics to avoid a severe reaction to the medications. If the problem is due to E. coli or the clostridium species, and is severe, the medications Ampicillin (20 mg/Kg B.W, IV) and Gentamicin (2.2 mg/Kg B.W, SC) are used.
Fluid therapy by Lactate Ringer’s 5 – 7% solution or oral ringer’s solution are considered to be effective. Hypoglycemia (low blood sugar) in a canine parvovirus infection is common; therefore glucose 5% should be added to the infusion. A blood transfusion is only needed if the anemia turns to “Low – Degree”, degrees of anemia are usually based upon hematological (blood) studies.
An added boost could be provided from a homeopathic remedy such as RunniPoo Relief. As always consult with a veterinarian to determine if this approach would be helpful for dog's specific condition. Herbal and homeopathic ingredients have a history of helping dogs have firmer stools and with overall bowel function.
