Dog Vaccinations Explained: Core, Optional and Boosters

Vaccines protect dogs against serious infectious diseases. Every dog needs the "core" vaccines; others depend on where you live and how your dog lives, such as kennels, travel or country walks. Puppies need a course of injections, then boosters as your vet advises. Some vaccines, such as rabies in many places, are also required by law. Your vet will set the right plan.

Vaccines and vaccination schedules: see your vet or a pet supply store with trained staff. Which vaccines your dog needs, and when, depends on its age, health, lifestyle and where you live.

Core and Lifestyle Vaccines

  • Core vaccines are recommended for every dog everywhere. The World Small Animal Veterinary Association lists vaccines against canine distemper, canine adenovirus (hepatitis) and canine parvovirus as core.
  • Regional vaccines become core where a disease is common. Rabies is core where it occurs, and leptospirosis vaccination depends on location.
  • Lifestyle vaccines depend on what your dog does, for example kennel cough vaccines for dogs that go to boarding kennels or daycare.

The Puppy Course and Boosters

Puppies get some protection from their mother at first, which fades over the early weeks. That's why puppies need a course of vaccinations a few weeks apart, finishing when they're old enough to respond well. Your vet will tell you when your puppy is protected enough to go out in public and mix with other dogs.

Adult dogs need boosters, but not every vaccine every year. Some last several years; others need topping up yearly. Your vet will tailor the schedule, and the annual check-up is still worth doing even in a year with no injections.

Questions to Ask Your Vet

  • Which vaccines does my dog need where we live and for our lifestyle?
  • When will my puppy be protected enough to go out and meet other dogs?
  • How often does each booster need repeating?
  • What do I need for boarding kennels, daycare or travel?
  • What should I watch for after a vaccination?

Keep your dog's vaccination record safe; kennels, groomers and travel all ask for it.

Frequently Asked Questions

Short answers; your vet has the long ones.

Does my dog need vaccines every year?

Not every vaccine. Some protect for several years, others need yearly boosters. Your vet will set a schedule, and a yearly check-up is still worthwhile.

When can my puppy go outside?

Your vet will tell you, based on your puppy's vaccinations and local risks. You can carry it out to see the world before then.

Is rabies vaccination required?

In many parts of the US, yes. In the UK and Ireland, it's needed for most travel abroad. Rules differ by country, so check locally.

Are vaccines safe?

Vaccines are widely used and most dogs have no problems. Mild tiredness or a sore spot can happen. Ask your vet what to watch for and call them if you're worried.

If your dog seems unwell after a vaccination, call your vet.
