What is Intestinal Virus (Reovirus)?
The reovirus belongs to the Reoviridae family, which is a small, yet mighty, group of plant and animal viruses. This virus keeps much needed, vital nutrients away from the intestinal wall. Since they cannot be absorbed into the muscles, dehydration and diarrhea occur. This group of viruses, or intestinal viruses, has double strands of RNA, or ribonucleic acid, and can affect most any mammal, including humans. Animals acquire the infection via feces or within the air. Since the virus limits the absorption of nutrients from the intestines, the results are very noticeable sickness in the dog, including symptoms of diarrhea and dehydration. Being situated in the walls of the dog’s intestines, the reovirus destroys the cells within the intestinal wall, thus causing the inflammation and other marked symptoms. This infection is also thought to be possibly associated with the transmission and subsequent infection of kennel cough.
Intestinal virus (reovirus) infection in dogs is a contagious illness caused by a virus from the Reoviridae family, leading to severe stomach and intestinal suffering by the infected dog. The illness commonly manifests with signs of gastrointestinal upset and upper respiratory illness.

Diagnosis of Intestinal Virus (Reovirus) in Dogs
There are several differential diagnoses to this illness, and the veterinarian will need to perform several tests to see what the precise diagnosis is. The veterinarian will perform a complete blood count, urinalysis and biochemistry profile. This is all in addition to the physical examination and a review of the dog’s symptoms with the veterinarian. The veterinarian may also test the dog’s feces and a serum antibody response test. He may also conduct virus isolation and a histopathology to differentiate this virus from others, such as canine viral enteritis, infectious tracheobronchitis, and other similar disorders.
Treatment of Intestinal Virus (Reovirus) in Dogs
There is no vaccine to prevent reovirus; however, scientists are currently developing an effective vaccine. Medications are usually not given for this virus.
