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.
Any condition that blocks light from getting to the retina impairs a dog’s vision. Corneal diseases and cataracts fall into this category. Glaucoma, uveitis, and retinal diseases are other important causes of blindness in dogs.

two to six weeks later can provide a retrospective diagnosis.

controlling vomiting and diarrhea, as described for the treatment of
