Bringing home a Boston Terrier puppy is exciting, and one of the first things on your to-do list is getting their vaccines started. Vaccines protect your puppy from serious, sometimes deadly diseases while their immune system is still developing.
This guide explains a typical puppy vaccine schedule, which vaccines are considered core and which are optional, and how to keep your Boston safe while the series is underway. It follows the general approach described in veterinary vaccination guidelines, such as those published by the American Animal Hospital Association (AAHA).
Please note: every puppy is different, and vaccine requirements vary by region and local law. Use this as a guide for conversations with your veterinarian, not a replacement for them.
Why Puppies Need a Series of Shots
Puppies get some protection from antibodies in their mother’s milk. Those maternal antibodies fade over the first few months, but while they are present they can also block a vaccine from working. Because no one can know exactly when a particular puppy’s maternal antibodies drop, puppies get a series of vaccines a few weeks apart until they are old enough that the last dose will reliably work.
That is why a single “puppy shot” is not enough, and why finishing the full series matters.
Core Vaccines vs. Non-Core Vaccines
Core vaccines
Core vaccines are recommended for essentially all dogs because the diseases are widespread, serious or a risk to people. For dogs in the United States these are:
- Distemper
- Canine adenovirus (hepatitis)
- Parvovirus
- Rabies
Distemper, adenovirus and parvovirus are usually given together in one combination shot, often labeled DAPP or DHPP (the extra “P” is parainfluenza, which is often included).
Non-core (lifestyle) vaccines
Non-core vaccines are recommended depending on where you live and your dog’s lifestyle. Common examples include:
- Leptospirosis, a bacterial disease spread through the urine of wildlife and contaminated water, which can also infect people
- Bordetella (part of “kennel cough”), often required by groomers, boarding facilities and daycares
- Canine influenza
- Lyme disease, in areas where ticks carrying Lyme are common
Your vet will help you decide which of these make sense for your Boston based on local disease risk, travel, boarding and outdoor activities.
A Typical Boston Terrier Puppy Vaccine Schedule
The schedule below reflects a common pattern. Your vet may adjust timing based on your puppy’s history and local needs.
| Age | Vaccines commonly given |
|---|---|
| 6 to 8 weeks | First DAPP/DHPP combination shot |
| 10 to 12 weeks | Second DAPP/DHPP; non-core vaccines (such as leptospirosis or Bordetella) may be started |
| 14 to 16 weeks | Third DAPP/DHPP; rabies (timing set by local law); second doses of non-core vaccines if started |
| 16 weeks or older | Final DAPP/DHPP dose at 16 weeks or later |
| About 1 year | Boosters for DAPP/DHPP and rabies, plus annual non-core vaccines as recommended |
| Adult years | Core vaccine boosters commonly every 3 years; rabies every 1 or 3 years depending on product and law; most non-core vaccines yearly |
In general, puppy combination shots are repeated every 2 to 4 weeks, with the last dose given at 16 weeks of age or older. If your puppy came from a breeder or rescue, bring any vaccine records you received so your vet can pick up where the last dose left off.
What to Expect at Vaccine Visits
Vaccine appointments are also wellness visits. Your vet will typically check your puppy’s weight, heart, eyes, ears, teeth and skin, and may discuss deworming, flea and tick prevention, and heartworm prevention. Our guides to your first vet visit and heartworm prevention cover those topics.
Possible side effects
Most puppies have no problems or only mild, short-lived effects, such as:
- Tiredness or sleeping more for a day
- Mild soreness or a small lump at the injection site
- A slightly reduced appetite
Call your vet promptly, or seek emergency care, if you notice facial swelling, hives, repeated vomiting or diarrhea, trouble breathing or collapse. These can be signs of an allergic reaction. Small breeds can be somewhat more prone to vaccine reactions, so if your Boston has reacted before, tell your vet. They may suggest spacing vaccines out over separate visits or keeping your puppy at the clinic for a short time afterward.
Keeping Your Puppy Safe Before the Series Is Done
Until your vet says your puppy is fully protected, avoid places where many unknown dogs go, such as dog parks, pet store floors and busy rest areas, because parvovirus can survive in the environment for a long time.
That does not mean keeping your puppy in a bubble. Early socialization is important for a confident adult dog. You can safely:
- Invite healthy, vaccinated dogs you know over to play
- Carry your puppy in public to experience new sights and sounds
- Join a puppy class that requires proof of vaccines and cleans its floors
- Practice handling, car rides and new surfaces at home
Our Boston Terrier puppy training tips and the Puppy Academy have more ideas for this stage.
Questions to Ask Your Vet
- Which non-core vaccines do you recommend for dogs in our area?
- When will my puppy be protected enough for the dog park or daycare?
- When is rabies required by law where we live?
- Should we space vaccines out given my puppy’s size?
- When should we start heartworm, flea and tick prevention?
Frequently Asked Questions
When can my Boston Terrier puppy go outside?
Your puppy can go out in your own yard for potty breaks right away, as long as unvaccinated dogs have not been there. Wait for your vet’s go-ahead before visiting public dog areas.
What if my puppy misses a vaccine?
Call your vet. In many cases they will simply give the next dose as soon as possible, but if too much time passes they may restart part of the series.
Do Boston Terriers need different vaccines than other breeds?
The core vaccines are the same for all dogs. What differs is lifestyle risk and individual history, such as a past vaccine reaction, so ask your vet to tailor the plan.
How much do puppy vaccines cost?
Prices vary widely by clinic and region. Ask your vet for an estimate for the full puppy series. Our guide to the annual cost of a Boston Terrier can help with budgeting.
Are titer tests an alternative to boosters?
Some vets offer antibody titer tests to check immunity to certain diseases before giving an adult booster. Titers do not replace rabies vaccination where it is required by law. Ask your vet whether titers are appropriate for your dog.
Consult your vet: Vaccine schedules should always be set by your veterinarian based on your puppy’s health, history and local requirements.
