Most puppies receive their first core vaccine (distemper/adenovirus/parvovirus - DA2PP) at 6–8 weeks of age, with additional doses every 3–4 weeks until at least 16 weeks. Shelter or orphan puppies may begin earlier or follow an accelerated protocol, and your vet will adjust timing based on maternal antibody risk and local disease pressure.

Core vaccines are DA2PP (distemper, adenovirus type 2, parvovirus, parainfluenza) and rabies; the typical puppy series for DA2PP starts at 6–8 weeks and continues every 3–4 weeks to 16 weeks or older, while rabies is normally given at 12–16 weeks with a legally required booster at 1 year then per local law. Adults get a 1-year booster for some products then repeat intervals per vaccine label and AAHA/AVMA guidance (often every 1–3 years depending on vaccine and titer results).

Booster frequency depends on the vaccine and local regulations: rabies boosters are dictated by law (commonly 1- or 3-year products), while most core vaccines move to extended intervals after the initial adult booster—commonly every 3 years—if titers show protective immunity. Non-core vaccines (bordetella, leptospirosis, Lyme) are typically given annually or per risk assessment.

Yes — for many core viral vaccines, AAHA supports using serologic titers to demonstrate protective immunity and guide revaccination decisions; a protective titer can allow postponing a booster. However, titer testing does not replace legally required rabies vaccination in jurisdictions that mandate vaccination, and availability/cost vary by clinic.

Mild reactions (lethargy, low-grade fever, soreness at the injection site) commonly occur within 24–48 hours and resolve without treatment; monitor your dog closely for 24 hours after vaccination. Seek immediate veterinary care if you see facial swelling, hives, vomiting, collapse or difficulty breathing, as these signs can indicate anaphylaxis requiring emergency treatment.

High-volume intake protocols often give an initial combination parenteral vaccine (DA2PP) at intake, a second dose 2–4 weeks later, and administer bordetella and leptospirosis per risk; rabies is given according to local law and may be required before adoption. Effective shelter protocols also include immediate isolation, documentation, expedited medical records, and standardized consent/forms for stray or owner-surrendered animals.

Seniors generally still need core protection, but vaccine plans should be individualized based on health status, comorbidities, and prior titer results; many clinicians rely more on titer testing and risk assessment for non-core vaccines in older dogs. Immunosenescence can reduce vaccine response, so your vet may choose shorter intervals, targeted vaccines only, or additional monitoring if immune compromise is present.

Boarding and daycare frequently require proof of up-to-date rabies and bordetella (kennel cough) vaccines, and sometimes DA2PP; international travel usually requires an up-to-date rabies certificate, a health certificate issued within a defined window (often 10 days), and country-specific tests or waiting periods (some require rabies vaccination at least 21–28 days before export). Always check the specific facility and destination country rules well in advance.

Maternal antibodies can neutralize vaccine response and vary by litter, often waning between 6 and 16 weeks; because of this variability, a series of vaccines spaced to at least 16 weeks improves the chance the puppy mounts its own protective response. Vets may delay the final dose or add an extra dose if maternal antibody interference is suspected.

For puppies, continue the series with remaining doses at 3–4 week intervals until the final recommended age (usually ≥16 weeks); for adults who miss a booster, consult your veterinarian—many core vaccines can be re-administered without restarting the series, while some non-core vaccines may require restarting depending on the elapsed interval and product label. Document all doses and consider titer testing to check current immunity before re-vaccinating.
