Canine Vaccine Recommendations

Vaccinations (immunizations, "shots") have saved the lives of millions of dogs. Before the days of effective vaccines, dogs routinely died from distemper, hepatitis, leptospirosis, parvovirus and complications of upper respiratory infections. Current vaccination programs protect our dogs (and us) from the threat of rabies. Newer vaccines, including those administered through the nostrils, have been developed to protect against a variety of infections.

Despite the well-known benefits of vaccination, the practice of annual vaccination of mature dogs is a matter of healthy debate. Some veterinarians believe that annual revaccination is an important and critical part of preventative health care. Others suggest that there is little scientific information to suggest that annual revaccination of older dogs is necessary for some diseases. There is growing evidence that the duration of immunity of properly vaccinated adult dogs extends beyond a year.

Of course, some vaccines (rabies) are required by law and must be administered on a regular basis.

Certainly routine vaccinations are essential for prevention of infectious diseases in puppies. Puppies receive immunity against infectious disease in their mother's milk; however, this protection begins to disappear between 6 and 20 weeks of age. The exact sequence cannot be predicted without specialized blood tests.

To protect puppies during this critical time, a well-researched approach is taken: a series of vaccines is given every 3-4 weeks until the chance of contracting an infectious disease is very low. The typical vaccine is a "combination" that protects against canine distemper virus, canine adenovirus, parainfluenza, and canine parvovirus (the four viruses are commonly abbreviated DHPP). Many veterinarians also recommend incorporating leptospirosis in the vaccination series.

Rabies vaccines are given between 16 and 26 weeks of age in most states (governed by law). All vaccines require booster immunizations ("shots") that are given one year later. Thereafter, the issue becomes cloudier.

The protective effect of vaccinations for bacterial infections (e.g. bordetella and leptospirosis) typically does not persist for more than a year making yearly (and occasionally more frequent) booster vaccines advisable. If your adult dog has an adverse reaction to the vaccine (fever, vomiting, shaking, facial swelling or hives) discuss the risk of annual revaccination with your veterinarian.

Recommendations

The foremost recommendation is to discuss the vaccination program with your veterinarian. Don't be hesitant to ask questions about the pros and cons of vaccinations.

Puppies 4 to 20 weeks of age: In puppies, a series of vaccines is recommended. These should begin between 6 and 8 weeks of age. Typically the last vaccination is given between 14 and 16 weeks of age. The vaccine should protect against canine distemper virus, canine adenovirus, parainfluenza and canine parvovirus. If the risk of kennel cough is great, a vaccine against bordetella is recommended. Rabies vaccine should be given in accordance with individual state laws usually between 16 and 26 weeks of age. Newer vaccines effective against specific forms of the bacteria leptospirosis may be important in some areas.

Dogs 20 weeks to 2 years: It is important to booster the puppy vaccines in young adult dogs to ensure adequate lifelong immunity against deadly viral diseases. Your veterinarian will likely "booster" your dog one year after the "puppy" vaccine series to protect against canine distemper virus, canine adenovirus, parainfluenza and canine parvovirus. If the risk of kennel cough is great, a vaccine against bordetella is recommended. The rabies vaccines should be given as recommended by local law. Newer vaccines effective against specific forms of the bacteria leptospirosis may be important in some areas.

Dogs older than 2 years: Annual revaccination (boosters) is recommended for the first year after the "puppy vaccines"; thereafter, you should discuss the benefits and risks of annual vaccination with your vet. In the past, the DHLP (distemper, hepatitis, leptospirosis, parvovirus) vaccine was typically given each year. These recommendations are changing. The American Animal Hospital Association (AAHA) came out with new guidelines in 2006 that suggests that adult dog vaccines boosters may be adequate if given every 3 years. Specific vaccine requirements for individual dogs should be discussed with your veterinarian. The most appropriate vaccination program for your pet should be followed.

Again, if the risk of kennel cough is great, a vaccine against bordetella is recommended. The bordetella vaccine needs to be given at least yearly, and each year you and your veterinarian should assess whether it is required. The rabies vaccine should be given as recommended by local law. Newer vaccines effective against specific forms of the bacteria leptospirosis may be important in some areas. The need for the vaccine should be determined based on the area of the country your dog lives in and his or her life-style. If given, they should be administered once to twice a year.

Other vaccinations that are sometimes given by your veterinarian include coronavirus, Lyme and giardia. These are not routinely given to every animal, and their use should be discussed with your veterinarian. The American Animal Hospital Association (AAHA) came out with new guidelines in 2006 that suggests that coronavirus and giardia vaccines are not recommended for dogs at any age. The Borreliosis/Lyme disease vaccine is recommended for dogs that live in an endemic area where risk of exposure to the tick vector is high or dogs that travel to endemic areas.
