This is a very broad question with no simple answer because our vaccine protocol is based on more than just the age of a pet. In general however, we recommend beginning vaccines at around 8 weeks of age and repeating every 4 to 5 weeks through 20 weeks of age. Puppies receive 4 DAP vaccines during that time period, and Bordetella (kennel cough) if needed. We vaccinate for Rabies between 4 to 6 months of age in most cases.
