Canine Distemper Virus (CDV) is a viral disease that affects the gastrointestinal, respiratory, and central nervous systems of dogs and other carnivores such as ferrets, raccoons, skunks, and foxes. It is highly contagious and potentially fatal, especially for younger puppies. CDV can be spread through direct contact (licking, breathing air, etc.) or indirect contact (bedding, toys, food bowls, etc.), though it cannot live on surfaces for very long. Inhaling the virus is the primary method of exposure. Symptoms of CDV include diarrhea, vomiting, thick yellow discharge from the eyes and nose, cough, and in severe cases, seizures and neurological signs, such as ataxia (stumbling), head tilt, and paralysis. The viral infection can be accompanied by secondary bacterial infections and can eventually present serious neurological symptoms. The diagnosis of CDV can be made by finding the virus by various methods in the dogs conjunctival cells or foot pads. There is no known cure for CDV, and quick response to the disease greatly improves the pets chances of survival. Vaccination is crucial in preventing canine distemper.
