Strictly the term diarrhea involves:
1. an unformed feces
2. an increase in frequency
3. an increase in volume
If your dog is only passing soft feces once or twice a day, although abnormal
it is strictly not diarrhea but merely looseness of the bowel.
What causes diarrhea?
Diarrhea is not a disease; rather, it is a sign of many different diseases.
Many mild cases of diarrhea can be resolved quickly with simple treatments.
Others are the result of fatal illnesses, such as cancer. Even diarrhea caused
by mild illnesses may become fatal if treatment is not begun early enough to
prevent severe fluid and nutrient losses.
How serious is diarrhea in dogs?
Your veterinarian will attempt to determine how sick the dog has become as
a consequence of the diarrhea When the dog is systemically ill (i.e., more than
one body system is involved), some of the following may be noted:
Vomiting, Dehydration, Loss of appetite, Abdominal pain, High fever, Lethargy,
Bloody and/or watery diarrhea
What types of tests are performed to find the cause?
If diarrhea is associated with several of the above signs, a series of tests
is performed in the hope that a diagnosis can be made. This permits more specific
treatment. Diagnostic tests may include radiography (x-rays) with or without
barium, blood tests, bacteriological cultures, biopsies of the intestinal tract,
and exploratory abdominal surgery. Once the diagnosis is known, treatment may
include special medications and/or diets, or surgery.
If your dog does not appear systemically ill from diarrhea, the cause may
be less serious. Some of the minor causes of diarrhea include stomach or intestinal
bacteria or viruses, intestinal parasites, and dietary indiscretions (such as
eating garbage or other offensive or irritating materials). A minimum number
of tests are performed to rule out certain parasites and infections. These cases
may be treated with drugs to control the motility of the intestinal tract, drugs
that relieve inflammation in the intestinal tract, and, often, a special diet
for a few days. This approach allows the body's healing mechanisms to correct
the problem. Improvement is expected within 2-4 days; if this does not occur,
a change in medication or further tests are done to better understand the problem.
