Some dogs that have recovered from canine adenovirous ( hepatitis) will develop “Blue Eye,” a clouding of the cornea. This usually resolves itself over time.
The disease is spread by direct contact of infected urine, faeces and saliva.
Dogs that have recovered from the disease can still be infectious, and spread the disease for more than 6 months.
Infectious canine hepatitis (ICH) is a disease which affects the kidney, liver, lungs and eyes of a dog. It is caused by canine adenovirus-1 ( CAV-1)
Puppies in their first year of life and unvaccinated dogs are most at risk of contracting hepatitis.
Many vaccines use the CAV-2 strain to protect against viral hepatitis, as this also provides cross-protection for some forms of kennel cough, and is less likely to cause “Blue Eye.”
All infected and in-contact dogs should be isolated from other susceptible dogs
Signs develop after an incubation period of about 4 -7 days.
Some cases of “acute” hepatitis which have gone on for just a few days can be cured.
For those with a more chronic form of hepatitas there is no cure.
However with proper treatment and monitoring, many patients with chronic hepatitis can live a good quality of life with minimal clinical signs.
In extreme case the disease can become severe very quickly and cause sudden death within hours.
Canine adenovirus / CAV-1 virus, cannot be treated directly.
Treatment to support the dog during the illness may include:
