Vaccination is one of the most important steps in protecting a new puppy from serious infectious diseases. A well-planned puppy vaccination schedule starts at about 6–8 weeks and continues every 3–4 weeks through 16 weeks, with boosters later as recommended by your veterinarian. This month-by-month approach ensures each dose builds immunity as your puppy grows, while allowing time to monitor for any reactions and adjust the plan to your dog's risk factors. Working with a veterinarian ensures vaccines are given at safe intervals and that the plan accounts for local laws and the puppy's overall health.

Month-by-Month Puppy Vaccination Schedule

Month 1: 6–8 weeks

First DHPP vaccine (core combination protecting against canine distemper, adenovirus-2/hepatitis, parvovirus, and parainfluenza)
Optional Bordetella vaccination for dogs at higher kennel, boarding, or social exposure
Optional leptospirosis or canine influenza vaccines based on risk in your area
Deworming and a fecal test may be recommended if your puppy’s risk factors suggest intestinal parasites
Record keeping: note the exact vaccines given and the expected boosters, and schedule the next visit in 3–4 weeks

Month 2: 10–12 weeks

Second DHPP dose to continue building immunity
Rabies vaccine is commonly given here if age and local regulations permit
Bordetella booster or re-administration if exposure risk remains high
Deworming or stool tests may be repeated if prior results indicated parasites
Next visit planned 3–4 weeks after this dose, or as advised by your vet

Month 3: 14–16 weeks

Third DHPP dose, typically the final shot in the core puppy series
Rabies vaccine administered if not given at the previous visit or as required by law
Consideration of non-core vaccines (such as canine influenza or additional leptospirosis protection) based on risk and lifestyle
Fecal testing if indicated by prior results or risk factors
Your veterinarian will help map the timing for the annual booster schedule

Month 4 and beyond: 6–12 months and beyond

Annual or triennial DHPP boosters, depending on vaccine type and local guidelines
Rabies vaccine boosters according to local legal requirements and health status
A tailored plan for risk-based vaccines (e.g., Bordetella, Canine Influenza) if your dog remains in high-exposure environments
Microchip updates and parasite prevention (flea, tick, and heartworm) reminders
Transition to a routine wellness schedule that includes annual checkups and preventive care

As you work through these visits, your vet will tailor the plan to your puppy’s health, growth, and living situation.

What to expect at vaccination visits

A quick health examination to assess appetite, activity, weight, and overall condition
Administration of vaccines as planned, with timing aligned to local guidelines
Microchip placement or verification if your puppy doesn’t already have one
Internal parasite screening or deworming as indicated by risk
A brief discussion about handling potential mild post-vaccination reactions and activity recommendations

Preparing for each visit can help reduce stress. Bring a current vaccination record, a stool test if your vet recommended one, and a list of any medications or supplements your puppy takes. If your puppy attends boarding or a doggy daycare, you’ll want to ensure vaccines are up to date prior to exposure.

Side effects and when to call the vet

Mild, common reactions: slight lethargy, decreased appetite, or a small lump at the injection site that resolves within a couple of days
Rare but important signs to watch for: vomiting, diarrhea, facial swelling, wheezing, collapse, or signs of severe pain
Most reactions are mild and self-limited; contact your vet if you notice anything concerning or if symptoms persist beyond 24–48 hours
Keep activity gentle for 24 hours after vaccination and monitor your puppy closely

If you ever see signs of a severe reaction, such as facial swelling or trouble breathing, seek urgent veterinary care immediately. Your Waggle Vet team can schedule a telemedicine check-in if you need quick guidance after a vaccine visit.

Preparing and following through

Maintain a vaccination log and set reminders for boosters
Discuss your puppy’s environment (dog parks, grooming, boarding) to tailor non-core vaccines
Continue preventive care including heartworm, flea, tick prevention, and a discussion about diet and weight management
If you notice persistent dental concerns or changes in appetite, you can explore our related posts on dog-bad-breath and diabetes resources for a broader health picture

By staying proactive and partnering with your veterinarian, you’ll build a strong foundation for lifelong health. This approach also helps you make informed decisions about boosters and non-core vaccines based on your puppy’s risk factors and local disease prevalence.

Conclusion

A thoughtful puppy vaccination schedule sets the stage for a healthy life together. Starting early, following the recommended vaccine sequence, and keeping up with boosters helps protect your puppy from serious diseases while giving you confidence in their ongoing wellness. Remember, your veterinarian is your best resource for personalizing this plan to your puppy's needs and local requirements. The goal is steady, predictable protection that fits your family’s pace and lifestyle while supporting a happy, active life for your pup.

Frequently Asked Questions

When should my puppy start vaccines? Puppies typically begin vaccines around 6–8 weeks of age, with subsequent boosters every 3–4 weeks until about 16 weeks. Your veterinarian will tailor the exact timing to your puppy’s health and local regulations.

Do all puppies need the Rabies vaccine? Rabies vaccination is legally required in many areas and is considered essential for protecting both pets and people. The timing of the first Rabies dose depends on local laws and the puppy’s age.

How often are boosters given after the initial series? After the initial puppy series, many dogs receive DHPP and Rabies boosters at intervals recommended by your veterinarian, often annually or every 1–3 years depending on the vaccine type and local guidelines.

Can vaccines cause adverse reactions? Most puppies tolerate vaccines well, with only mild, short-lived side effects. Severe reactions are uncommon but require urgent veterinary attention. Contact your vet if you notice persistent vomiting, facial swelling, or breathing difficulties.

Should I space vaccines out if my puppy is anxious or sensitive? Some puppies benefit from a slower vaccination plan or additional comfort measures.
