Chronic Diarrhea in Dogs: What Do We Actually Know About It?

Abstract

There is a paucity of research based knowledge about chronic diarrhoea in dogs. In the literature no studies can be found that confirms that round worm, whip worm, hook worm or giardia cause chronic diarrhoea in dogs. For this reason, it is questionable to study endoparasites when clarifying the reason for chronic diarrhoea in dogs. No study confirms that clostridium-, campylobacter- or salmonella species cause chronic diarrhoea signs in dogs. There is no research-based information to-date that endoscopy would be helpful in the diagnosis of dogs with chronic diarrhoea or to monitor how the disease progresses. Neither no reliable laboratory test can be recommended to be used in evaluating the seriousness of the disease or to monitor the progress of the disease. There is no evidence based information on what food should be recommended for dogs suffering from diarrhoea. Only a few studies have been published that show how effective antibiotics are in the treatment of diarrhoeal dogs. Many more studies are needed before it is possible to determine how effective corticosteroids are in the treatment of diarrhoea in dogs.
