Puppies need a series of vaccines in their first months to build protection against serious diseases like parvovirus and distemper. Enter your puppy’s date of birth to get a suggested vaccine timeline you can print or add to your calendar, then confirm the exact dates with your veterinarian.
Why puppies need several doses
Newborn puppies get temporary protection from antibodies in their mother’s milk. Those antibodies fade at an unpredictable time between roughly 6 and 16 weeks of age, and while they are present they can stop a vaccine from working. Giving a series of doses every few weeks makes sure at least one dose works once the mother’s antibodies are gone. That is why the final dose at 16 weeks or older is so important.
Core vs. lifestyle vaccines
Core vaccines are recommended for every dog: distemper, adenovirus (hepatitis), parvovirus and rabies. Lifestyle vaccines, such as leptospirosis, Bordetella, canine influenza and Lyme disease, depend on where you live and what your dog does. Learn more in our guide to core and non-core dog vaccines.
Keeping your puppy safe until they are fully vaccinated
- Avoid dog parks, pet store floors and other places where many unknown dogs go until your vet says it is safe.
- Socialization still matters: carry your puppy to new places, invite calm, vaccinated adult dogs over and join a puppy class that requires vaccine records.
- Watch for vomiting, diarrhea, lethargy or not eating, and call your vet right away if they appear, as these can be signs of parvovirus.
