The topic of vaccinations is the subject of some debate amongst pet professionals. Which ones are strictly necessary and how often they should be administered is at the heart of the discussion, with some prominent veterinarians arguing that dogs in America are over-vaccinated, solving some problems while simultaneously causing others.

I believe that we must find a balance between veterinary science and Mother Nature. Vaccines can provide much-needed protection from many life-threatening illnesses, but a dog's body also has its own natural defenses. It is equally important that your dog be physically fit and psychologically healthy in order to help her develop the fortitude she needs to fight off potentially dangerous diseases.

Vaccinations can play an important part in helping your dog live a long, healthy life, but you should feel confident that she is not receiving unnecessary shots. Many of the vaccines traditionally administered once a year to dogs are no longer suggested in annual dosages. Instead, some experts are now recommending that they be given once every three years, or in some cases even just once in a lifetime.

The American Animal Hospital Association updated their vaccine guidelines in 2006, separating them into three categories: Core, Non-Core, and Not Recommended. More information can be found on their website.

As always, I recommend that you sit down to discuss your options with your veterinarian, do plenty of your own research, and bring up the subject of canina vaccinations with other dog professionals or owners with whom you have trust and respect. Your decision to vaccinate your dog and how often to do it should be carefully considered and well-informed.
