Inc. Enteritis is the term used to describe an inflammation or infection of the small intestine. In the dog, many bacteria and viruses have been implicated as a cause of enteritis. Among them are parvovirus, coronavirus, rotavirus, salmonellosis, distemper virus and many others. Most of these organisms affect other areas of the body as well, however, some of their principle signs of infection are associated with the small intestine.
Diarrhea is the most common sign associated with small intestine diseases.
With enteritis, the temperature is commonly elevated. However, especially with viruses, this is not always the case. A characteristic fetid odor from the feces is usually detected. Contrary to popular belief, one cannot differentiate diarrhea caused by Parvovirus from other sources without sophisticated laboratory testing. The diarrhea from these various causes may all smell similar.
