Please visit the AAHA site to review recommended canine vaccine guidelines.
All puppies should have received an initial dose of the CORE vaccines prior to leaving the breeder. Owners should complete the puppy series, as recommended.
As the site says, non-CORE vaccines vary with where you live, prevalence of disease in your area and the lifestyle you and your pup will live.
From the AAHA site:
“Licensed canine vaccines have a high degree of proven safety and efficacy. For this reason, dogs that present with an incomplete or ambiguous vaccination or health history can still be vaccinated with the expectation of a protective immune response and a low risk of serious post vaccination adverse effects. Stated another way, veterinarians can assume that the benefits of vaccination far outweigh the risks in cases of dogs with unknown immune status or vaccination history—a common occurrence in veterinary practice. Examples of these real-world scenarios include the possibility of recent natural exposure, absence of serologic data to guide a vaccination decision, or suitability for noncore vaccines such as Leptospira spp. Thanks to the reliability of the licensed vaccine armamentarium, a good rule of thumb is, “When in doubt, vaccinate.””
