How often does my dog need vaccines?

Staying on top of your dog’s vaccination schedule is one of the most important things you can do for their long-term health. But the timeline can feel confusing, especially for new dog owners navigating puppy visits, booster dates, and vet recommendations that seem to vary from clinic to clinic.

Here is a straightforward guide to what is involved and how to keep it all organised.

Core vs non-core vaccines

Vets divide dog vaccines into two categories: core and non-core.

Core vaccines are recommended for virtually every dog, regardless of lifestyle. They protect against diseases that are widespread, severe, or transmissible to humans. The main core vaccines for dogs are:

  • Distemper
  • Parvovirus
  • Adenovirus (hepatitis)
  • Rabies (required by law in many countries and regions)

These are often given as a combined injection. You may see abbreviations like DA2PP, DHPP, or similar depending on the formulation your vet uses.

Non-core vaccines are recommended based on your dog’s individual risk level, which depends on where you live, your dog’s lifestyle, and the advice of your vet. Common non-core vaccines include:

  • Bordetella (kennel cough), especially relevant if your dog uses boarding facilities or dog parks
  • Leptospirosis, more common in dogs with outdoor exposure, particularly near standing water
  • Canine influenza
  • Lyme disease (region-dependent)

Your vet is the best person to advise which non-core vaccines make sense for your specific dog.

The puppy vaccination series

Puppies receive a series of injections in their first few months of life. This is because maternal antibodies (passed through the mother’s milk) gradually wane, leaving windows where the puppy is vulnerable to disease. The series is designed to catch the puppy as those maternal antibodies fade.

A typical puppy schedule might look something like this:

  • 6 to 8 weeks: First combination vaccine
  • 10 to 12 weeks: Booster
  • 14 to 16 weeks: Final puppy booster, often including rabies
  • 12 to 16 months: A final “puppy series close-out” booster that many vets recommend

The exact timing varies by vet clinic, vaccine brand, and country. Always follow the specific guidance your vet gives you.

Adult boosters

After the puppy series is complete, most dogs move to a booster schedule. This typically means:

  • A booster around 12 months after the final puppy shot
  • Then core vaccines every one to three years, depending on the specific vaccine and your vet’s protocol

Rabies vaccine schedules in particular are often governed by local regulations, so the interval can vary.

Non-core vaccines like Bordetella may require annual or even more frequent boosters, depending on the product used and your dog’s exposure risk.

Why schedules vary

If you compare notes with other dog owners and find your schedules differ, that is completely normal. Vaccine timing depends on:

  • The specific products your vet stocks
  • Local disease prevalence
  • Your dog’s health history and any previous reactions
  • Your country or region’s regulatory requirements

This is why it is always worth confirming the recommended schedule directly with your own vet rather than relying solely on general guides like this one.

Keeping track of it all

With puppy shots every few weeks, then annual or triennial boosters across multiple vaccines, it is easy for dates to slip. Missed boosters can mean the protection fades earlier than expected, or that a puppy series is not considered properly closed.

Maggie is built to help with exactly this. When you add your dog and their birthday, Maggie builds an age-aware vaccine schedule and sends you a phone reminder before each dose is due. You can log each vaccination as it is given, attach a photo of the certificate if you want a record, and see the full history at any time.
