Canine coronavirus is
a contagious intestinal infection that usually produces a mild disease.
However, it can be severe in young puppies and dogs
who are stressed by concurrent infections. The distribution is worldwide, and
dogs of all ages are affected.
Coronavirus is transmitted by contact with infected oral and fecal
secretions. Following infection, the virus is shed in the stool for many
months. Symptoms vary from none (the most common form) to outbreaks of acute diarrhea,
typically occurring in a community of dogs. Dehydration
can occur if the diarrhea is severe.
Canine parvovirus is a highly contagious viral disease that can produce a life-threatening illness. The virus attacks rapidly dividing cells in a dog’s body, most severely affecting the intestinal tract. Parvovirus also attacks the white blood cells, and when young animals are infected, the virus can damage the heart muscle and cause lifelong cardiac problem
The early signs of illness are depression with loss of appetite, followed by
and the passage of a foul-smelling, yellow to orange diarrhea that varies from
soft to watery. The diarrhea may contain blood. Unlike parvovirus, fever is
There is no readily available test to diagnose coronavirus during the acute
illness. A rise in antibody titer in serum tested at the time of illness and
two to six weeks later can provide a retrospective diagnosis.
Treatment: Treatment is supportive, and includes maintaining hydration and
controlling vomiting and diarrhea, as described for the treatment of

Prevention: A vaccine is available to control coronavirus. However, because

is not recommended.
