Puppy Vaccine Schedule: Complete 2026 Guide with Costs

Most puppies begin their vaccine series at 6 to 8 weeks. A common schedule is:

• 6 to 8 weeks: first DA2PP/DHPP
• 9 to 12 weeks: booster DA2PP/DHPP
• 12 to 16 weeks: additional DA2PP/DHPP boosters every 3 to 4 weeks as needed
• 12 to 16 weeks or older: rabies, based on state law and product labeling
• 12 to 16 months: booster for core vaccines after the puppy series

The key point is not the exact brand name on the label. It is that the final puppy dose of the distemper-parvo-adenovirus series should be given at 16 weeks of age or later, and some higher-risk puppies may continue through 18 to 20 weeks if your vet feels that is appropriate.

Core vaccines are the ones recommended for nearly all puppies because the diseases are severe, widespread, or have public health importance.

For puppies, core vaccines generally include:

• Distemper
• Parvovirus
• Adenovirus-2 (protects against infectious hepatitis)
• Rabies

These are often bundled into one combination shot such as DA2PP, DAPP, or DHPP. Rabies is usually given separately. In recent AAHA updates, leptospirosis is also strongly recommended broadly for dogs because exposure can occur in many everyday environments and it can infect people as well.

Some vaccines are based on exposure risk rather than being needed for every puppy. Your vet may discuss:

• Leptospirosis: often recommended for many dogs because wildlife, puddles, wet soil, and urban rodents can spread it
• Bordetella: commonly required for boarding, daycare, grooming, and group classes
• Canine influenza: considered for dogs with frequent close contact with other dogs in group settings
• Lyme disease: considered in tick-heavy regions or for dogs with outdoor exposure in endemic areas

These vaccines are not automatically right for every puppy. They are tools your vet can use when your puppy's routine, travel plans, and local disease risk make them worthwhile.

Puppies are not fully protected after one shot. Maternal antibodies from nursing can interfere with early vaccination, and that protection fades at different rates in different puppies. Because of that, the vaccine series is designed to catch the window when maternal antibodies are low enough for the vaccine to work but before the puppy is left unprotected.

Missing boosters can leave gaps in immunity. If your puppy is late for a visit, call your vet rather than guessing. In many cases, the schedule can be adjusted without starting completely over, but the right plan depends on your puppy's age, vaccine history, and risk level.

In the United States in 2025-2026, a routine puppy vaccine visit often includes an exam plus one or more vaccines. A general cost range is:

• Office visit/exam: about $40 to $90
• Core vaccine dose: about $20 to $60 per vaccine
• Rabies vaccine: often $20 to $50 depending on clinic and local fees
• Bordetella or leptospirosis: often $25 to $55 each
• Low-cost vaccine clinic: sometimes $15 to $35 per vaccine, though services may be more limited

A full puppy vaccine series over several visits commonly totals about $150 to $400+, depending on region, exam fees, vaccine choices, and whether fecal testing, deworming, microchipping, or preventives are added.

Socialization is important during puppyhood, but disease exposure matters too. Puppies are at highest risk for infections like parvovirus before they finish their vaccine series. That does not mean they must stay isolated. It means socialization should be planned.

Your vet may suggest safer options such as meeting healthy, fully vaccinated dogs you know, visiting clean private yards, or attending well-managed puppy classes that require age-appropriate vaccines. High-risk places like dog parks, unknown dog traffic areas, and contaminated public spaces may need to wait until your puppy has stronger protection.

Many puppies have no side effects at all. Mild reactions can include sleepiness, mild soreness, a small lump at the injection site, or a lower appetite for a day.

Call your vet promptly if you notice vomiting, diarrhea, facial swelling, hives, trouble breathing, collapse, severe lethargy, or persistent pain after vaccination. These reactions are uncommon, but they need medical attention. If your puppy has reacted to a vaccine before, tell your vet before the next visit so the plan can be adjusted.

The puppy series is not the end of vaccination. Puppies usually need a booster at 12 to 16 months of age after the final puppy shots. After that, booster timing depends on the vaccine type, product label, local law, and your puppy's risk profile.

For many adult dogs, distemper-parvo-adenovirus boosters are then spaced at longer intervals, while rabies timing follows the law and the vaccine used. Lifestyle vaccines such as Bordetella, leptospirosis, influenza, or Lyme may be boosted more often if your dog's exposure risk continues.
