Your Dog and Canine Distemper Virus (CDV) (Part 1)
Puppies between the ages of three and six months are most susceptible to the disease, although older dogs and other carnivorous mammals can also contract distemper. At one time, distemper was the leading cause of death among puppies that had not been vaccinated. Since the distemper vaccine was created in the early 60s, incidents of distemper and distemper related deaths have dropped considerably.
CDV is transmitted via airborne viral particles that dogs inhale. Infected dogs also shed the virus through bodily secretions and excretions. In this manner it is easy for an infected dog to cause the infection of another dog.
Distemper causes a multitude of symptoms that include various respiratory and gastrointestinal symptoms to central nervous system disorders. In fact, dogs that die as a result of distemper actually die from central nervous complications caused by the disease or from secondary bacterial infections.
