What Are the Benefits of Distemper Shots for Dogs?

As a dog owner, it might seem obvious that you should get yearly vaccinations for your pet to prevent common diseases. One such disease is the canine distemper virus (CDV), which can be debilitating and deadly to your dog. Sometimes, however, the side effects of the vaccination can cause more problems than the actual disease, and a dog owner may need to decide whether or not the benefits outweigh the risks.

  1. What is Distemper?

    • Distemper, also known as canine distemper virus (CDV), is a disease that is very contagious and life-threatening to dogs. It spreads via mucous or watery secretions from the eyes or nose. CDV can also be transmitted via air and can survive on inanimate objects that may have come in contact with an infected dog's urine, mucus, or other secretions.

      According to Dr. Spielman, DVM, over 50 percent of dogs that contract CDV die from it. Those that may survive suffer irreparable damage to the nervous system, causing partial or total paralysis and seizures.

    Symptoms

    • CDV affects the gastrointestinal, respiratory, and nervous systems. Symptoms can vary from mild--such as discharge from the eyes and nose, discoloration of teeth, and depression--to severe, such as anorexia, vomiting, seizures, paralysis, blindness, diarrhea, or lack of muscle coordination. If you see any of these symptoms, contact your veterinarian.

    Benefits of Vaccination

    • The obvious benefit of giving your dog a distemper vaccination is protection. The vaccine not only protects your dog, but other dogs as well.

    Debate About Booster Shots

    • How often should dogs get revaccinated for CDV? In the past, the CDV vaccine was recommended as an annual booster shot. Some vets, however, counter that annual canine distemper vaccinations may not be necessary. Instead, they recommend a vaccination booster every three years. They support the three-year booster versus the one year, because the CDV vaccination seems to protect dogs longer than previously thought.
