Bernese Puppy Vaccine & Vet Schedule

By the Riverside Berner Guide editorial team
Last updated November 7, 2026

A Bernese puppy vaccination schedule follows the same core plan as any puppy’s: a series of combination shots that starts around 6 to 8 weeks and repeats every few weeks until the puppy is past 16 weeks, then a booster within a year. Rabies timing is set by state and local law. Your vet sets the exact dates, so use the ranges below to plan visits and ask good questions.

Nothing here replaces your vet’s advice. The guidelines we cite are written for vets, who adjust them for each puppy’s health, history and where you live.

The Bernese puppy vaccination schedule at a glance

Here is how the major veterinary guidelines lay out a puppy shot schedule. Treat these as ranges, not dates to book on your own.

Your breeder has probably given the first shot or two already. Bring those records, and your vet will pick up from there.

Core vaccines for dogs, and why puppies need a series

The American Animal Hospital Association (AAHA) calls a vaccine “core” when it’s recommended for every dog, whatever its lifestyle, unless there’s a medical reason not to. Its 2022 guidelines list distemper, adenovirus type 2, parvovirus and rabies as core. The first three usually come together in one combination shot, sometimes with parainfluenza added.

Why one shot isn’t enough

A puppy gets antibodies from its mother. Those antibodies protect it early on, but AAHA explains that they can also block a vaccine from working. They fade at different rates, and for parvovirus they may last 13 to 15 weeks or longer.

Nobody can tell exactly when a given puppy’s maternal antibodies will drop. So vets give doses every 2 to 4 weeks until the puppy is older than 16 weeks, AAHA says. Where the risk of distemper or parvovirus is high, it notes that continuing to 18 to 20 weeks may be preferred.

How many shots do puppies need?

AAHA’s table calls for at least three doses of the combination vaccine between 6 and 16 weeks, given 2 to 4 weeks apart. Then a single booster goes within a year of the last puppy dose, with boosters every 3 years after that.

The World Small Animal Veterinary Association (WSAVA) is close but not identical. Its 2024 table suggests repeating every 3 to 4 weeks until 16 weeks, and considering a dose at about 6 months rather than waiting until 12 to 16 months. Ask your vet which approach they follow and why.

The rabies rule: set by state and local law

Rabies is different from the other core shots because the law, not just your vet, decides the timing. AAHA notes that the age for the first shot, the booster timing and whether exemptions exist can all be written into law. Those rules can be set at the local or state level.

So when do puppies get the rabies shot? The CDC says to vaccinate dogs according to local laws and that most shouldn’t be vaccinated before 3 months (12 weeks) of age. AAHA says all licensed rabies vaccines are labeled for puppies 3 months and older, with a booster 1 year after the first dose.

Your vet will know your state’s deadline and any city or county rules. Keep the rabies certificate with the rest of your puppy’s records.

Spacing rabies from other shots

The BMDCA’s puppy’s first year sheet suggests not giving rabies at the same visit as a combination vaccine, to lower the chance of a reaction.

AAHA says there’s no evidence that giving several vaccines at once weakens protection. It does note that spreading vaccines across visits can lower reaction risk, and suggests at least 2 weeks between visits when doing so. This is a judgment call for you and your vet.

Lifestyle vaccines to ask about

Beyond the core shots, AAHA’s 2022 guidelines list noncore vaccines that depend on where you live and what your dog does, such as Bordetella, Lyme disease and canine influenza. Leptospirosis was on that list too, but AAHA has since changed its advice.

Leptospirosis deserves a real conversation with your vet. In 2024, AAHA updated its canine vaccination guidelines to move the leptospirosis vaccine from non-core to core for most dogs, following consensus statements from the American College of Veterinary Internal Medicine (ACVIM) and WSAVA, AAHA reported in June 2024. For timing, the 2022 guidelines give a first dose at or after 12 weeks, a second 2 to 4 weeks later, then yearly boosters.

WSAVA’s 2024 guidelines call it core where canine leptospirosis is endemic, meaning the disease is common in the area. Ask your vet whether and when your puppy should get it, based on where you live and where you travel.

The puppy deworming schedule

Worms are common in young puppies. The Companion Animal Parasite Council (CAPC) explains that roundworm larvae can pass from a mother to her puppies before birth, so some are born infected.

CAPC’s general guidelines advise treating puppies from 2 weeks of age, then every 2 weeks until regular year-round parasite control begins. If year-round control isn’t kept up, CAPC describes deworming every 2 weeks until 2 months, then monthly until 6 months. It also recommends stool tests at least four times in the first year.

Ask the breeder for the dates and products used so far, then ask your vet what comes next. Product choice and dosing are your vet’s call.

Your puppy’s first vet visits

Set up vet care before you bring your puppy home. The BMDCA’s first-year sheet says the purchase agreement should give you a few days for your own vet to examine the puppy. AKC notes that breeder contracts usually ask for that exam within about three days.

What to bring

• The breeder’s vaccine and deworming records
• A fresh stool sample, since AKC says most puppies have roundworms
• Your questions, written down

What the vet checks

AKC lists weight, heart and lungs, temperature, eyes, ears, skin and coat, teeth, belly and a stool check. The BMDCA adds points to watch in a Berner puppy, such as heart murmurs, eyelid fit, the bite, both testicles in a male, and umbilical hernias, which it says are common in the breed.

The club also warns that a clean stool test on day one doesn’t rule out parasites later. It suggests checking again at a vaccine visit. Watery diarrhea in a young puppy can dehydrate it within a day or two, so call your vet right away if you see it.

Follow-up visits

Plan on a visit every few weeks while the shot series runs, then yearly checkups. The BMDCA says annual exams should be part of every Berner’s care. Our guide to the cost of owning a Bernese can help you budget for them.

Socialization while the shots are underway

You don’t have to keep your puppy home until the series ends. The American Veterinary Society of Animal Behavior (AVSAB) says the first three months are the most important time for socialization. It recommends that puppies be socialized before they’re fully vaccinated.

The AVSAB says puppies can start classes at 7 to 8 weeks. They should have at least one set of vaccines 7 days before the first class, plus a first deworming, and stay current after that. It advises skipping dog parks and other busy, unsanitized dog areas.

This matters for Berners. The BMDCA’s FAQ says shyness can run in the breed and stresses exposing young Berners to many people, places and animals in the first year.

Large-breed growth notes for the first year

Bernese puppies grow fast, and the goal is steady growth, not speed. Cornell’s Riney Canine Health Center advises a commercial large-breed puppy food that meets AAFCO standards for growth. It says not to add calcium, vitamin D or extra protein to a complete diet, and to keep puppies lean, with ribs easy to feel and a visible waist.

Cornell’s hip dysplasia page says overfeeding and rapid growth can make hip dysplasia worse in dogs already prone to it. Ask your vet to check your puppy’s weight and body shape at each visit.

Exercise matters too. The BMDCA’s first-year sheet says puppy exercise should never be forced, such as jogging or long rough play. Cornell advises limiting repetitive high-impact exercise during rapid growth.

Hips and spay or neuter timing

Ask your vet early about hip screening. Cornell says puppies of at-risk breeds can be screened for hip looseness with PennHIP before 20 weeks, while a final OFA hip grade needs X-rays taken after age two.

Spay or neuter timing is a medical decision with trade-offs for big breeds. See when to spay or neuter a Bernese, then ask your vet.

Questions to ask your vet

Bring this list to the first appointment:

• Which core and lifestyle vaccines do you recommend for my puppy, and when?
• What does our state and city require for rabies?
• Do you give rabies on the same day as other shots?
• Which parasite control do you recommend, and how often should we test stool?
• How should my puppy’s weight and growth look at each visit?
• When should we talk about hip screening and spay or neuter timing?

Where this fits in your puppy plan

Vet care starts before your puppy comes home. If you’re still choosing, read how to pick the right Bernese puppy from a litter, and ask the breeder for full vaccine and deworming records. Our guide to the Bernese Mountain Dog price covers the up-front costs.
