We believe that over vaccinating can cause more harm than good to our goldens.
Unfortunately we didn't find this out until 2 years ago when one of our goldens had a bad reaction to his shots. After reading many articles and books about the damages vaccines can do I have stopped vaccinating my adult dogs. I will do blood titers every year on all my goldens now and it has shown that they have immunity to the vaccines.
I do not vaccinate my puppies and recommended that you wait until the pups are at least 14 weeks old before vaccinating. All my pups are vet checked for health guarantee before going to their new homes.

Please see the attached list of recommended books for your reading:
