A Condition Caused by Canine Hepatitis by Race Foster, DVM and Marty Smith, DVM Drs. Adenovirus type 1 is a severe viral disease affecting dogs of all ages. About 10 days after exposure to the virus , the corneas appear blue or very hazy. Most patients squint and the eye may tear excessively.
Puppies are more commonly involved than adults.
This reaction is seldom seen with modern vaccines. Once the patient's body fights off the viral infection, the eyes will clear. Several weeks may be required for the eyes to become normal again. In severe cases involving the liver, death can result. Fortunately, excellent and safe vaccines for adenovirus type 1 are available and usually administered yearly to prevent this disease.
