Canine distemper is the greatest disease threat to the dog population.
The disease is highly contagious and can damage the nervous system, sense of smell, hearing and sight. It can also cause partial or total paralysis. The virus is also air borne and can be on inanimate objects. Many signs of distemper may mimic other less severe illnesses such as a severe cold. This virus is diagnosed on the basis of laboratory tests, history of the patient, and clinical signs.
