Dog Vaccination Schedule for Puppies and Adult Dogs: How Many Shots, When, and How to Prepare

"How many shots does a dog need?", "When can a puppy be vaccinated?", "How much do dog vaccinations cost?" Almost every new dog owner has searched for these. Vaccination is one of the most effective ways to protect dogs from dangerous infectious diseases such as parvovirus, distemper, infectious hepatitis and rabies. This article explains common vaccination schedules, what to watch out for, and how to keep track so you never miss a shot.

Note: This is general information. Your dog's exact schedule should be decided by a vet based on its age, health, vaccination history and living environment.

Puppies receive some antibodies from their mother's milk, but these fade over time. This creates an "immunity gap" that leaves unvaccinated puppies vulnerable. Diseases like parvo and distemper progress quickly, are costly to treat and can be life-threatening. Rabies is also dangerous to people.

Vaccination protects not only your dog but also other animals and your family.

Vets usually divide dog vaccines into two groups:

• Core vaccines: recommended for most dogs, covering parvovirus, distemper, infectious hepatitis (adenovirus) and rabies. In Vietnam, rabies vaccination for dogs is required under local regulations.
• Non-core vaccines: given depending on risk, for example kennel cough, leptospirosis or canine coronavirus. Your vet will advise based on whether your dog goes out often, stays at pet hotels or meets many other dogs.

At clinics you will often hear about "5-in-1" or "7-in-1" vaccines. These are combination vaccines that protect against several diseases in one shot. Ask your vet exactly which diseases a given shot protects against.

Based on general recommendations from international veterinary organisations, a typical puppy schedule is:

• First shot: usually at around 6–8 weeks of age.
• Boosters: about 3–4 weeks apart until the puppy is around 16 weeks old or older. This is why puppies get a series of shots rather than just one.
• Rabies: usually from around 3 months of age, as directed by your vet.

The exact number of shots depends on the vaccine, when the series starts and your puppy's condition. A dog adopted later or with an unknown history may need a different schedule.

After the initial series, dogs need regular boosters to maintain immunity. There is usually a booster about a year after the initial series, after which your vet will set the next intervals depending on the vaccine. Rabies boosters are usually given yearly or as required by regulations.

If you adopt an adult dog with an unknown vaccination history, take it to the vet for an assessment and a suitable schedule.

Before vaccination:

• Your dog should be healthy: eating normally, no fever, no diarrhoea, no vomiting. The vet will do a general check first.
• Many clinics recommend deworming before vaccination. Ask your vet about the right order and timing.
• Bring the vaccination book or health record so the vet knows what your dog has had.

After vaccination:

• Some dogs may be a little tired, eat less or have mild swelling at the injection site for a short time.
• Contact your vet right away if you see unusual signs such as facial swelling, repeated vomiting, difficulty breathing or marked lethargy.
• Limit bathing and strenuous exercise for a few days, following the clinic's advice.
• Puppies that haven't finished their shots should avoid unfamiliar dogs and places with many dogs.

Costs vary by clinic, area and vaccine type (combination vaccines, rabies vaccine, manufacturer and so on). The best way is to ask the clinic directly before you go. Compared with the cost of treating diseases like parvo or distemper, full vaccination is usually the more economical and safer choice.

If you want to plan ahead for your dog's long-term health costs, you can look into PetCare plans with pet care cost support on PetID.
