Although most cases of acute diarrhea are short-lived and self-limiting, there are some cases that require diagnostic testing to confirm an underlying cause. Such tests include: Complete history and physical examination
Fecal studies - flotation, smear, and zinc sulfate for Giardia
Complete blood count (CBC)
Abdominal radiographs (x-rays)
Diarrhea is a symptom that can be caused by many different diseases or conditions. Specific treatment requires a diagnosis. The diagnostic tests described previously may reveal a diagnosis, however, in the interim symptomatic therapy may be helpful to reduce the severity of signs and offer relief to your pet:
Placing the intestinal tract in a state of physiologic rest by withholding food for 12 – 24 hours
Subsequent change to a bland, easily digestible diet
Intestinal protectants and adsorbents
If Your Dog Has Diarrhea
Administer only prescribed medications.
Provide fresh water or oral rehydrating solutions to help prevent dehydration.
Temporarily change the diet to something bland. Bland diets can be made at home or prescription type diets can be obtained from your veterinarian.
Observe your dog's general activity and appetite, watch closely for the presence of blood in the stool, worsening of signs, or the onset of vomiting.
Have your pet examined by your veterinarian if you have any questions or concerns.
