Puppy and Kitten Vaccination Schedule: The Complete Timeline

Timing matters as much as the vaccine itself. Here's the complete puppy and kitten vaccination timeline we follow at TruVet, week by week, and why skipping a dose can leave a real gap in protection.

Puppy and Kitten Vaccination Schedule: The Complete Timeline

By Dr. Brajmadhuri, TruVet Pet Care Clinic, Sector 79, Gurgaon

One of the most common questions new pet parents ask us is some version of, "Does it really matter if we are a week or two late?" The honest answer is that timing is a real part of how these vaccines work, not just a scheduling formality that exists to keep a clinic busy. Here is the full timeline, and the reasoning behind it, so you know what to expect at each stage of your puppy or kitten's first several months.

Why the schedule is spread out over weeks

Puppies and kittens are born with some protection borrowed from their mother, passed on through her milk in the first days of life. This natural protection is genuinely useful in those very early weeks, but it fades gradually over the first few months, and while it is still present in the body, it can actually get in the way of a vaccine's ability to build the puppy or kitten's own protection from scratch.

Because nobody can know the exact week that this natural protection wears off in any individual animal, we vaccinate in a series, spaced a few weeks apart, so that by the time the mother's protection fades completely, one of those later doses is ready to take over and build real, lasting protection of its own. This is also exactly why a single early vaccine, on its own, is not considered a complete puppy or kitten vaccination. The series matters as much as any individual dose within it.

Puppy vaccination timeline

The first dose of the combination vaccine, which protects against several common and serious viral illnesses including parvovirus, is generally given between six and eight weeks of age. Between ten and twelve weeks, we give a second dose of that same combination vaccine, along with the first dose of the leptospirosis vaccine. Then, between fourteen and sixteen weeks, your puppy gets a third dose of the combination vaccine, a second leptospirosis dose, and the anti rabies vaccine, which is legally mandatory for dogs in India regardless of breed or lifestyle. From that point on, the combination vaccine, leptospirosis, and rabies are all repeated every year for the rest of your dog's life. Depending on your dog's lifestyle, we may also discuss extra vaccines such as kennel cough protection, particularly if your dog is likely to spend time at boarding, daycare, or grooming facilities where dogs mix closely together.

Kitten vaccination timeline

Kittens follow a similar logic on a slightly different schedule. The first dose of the combination vaccine for kittens, which protects against several common and serious viral illnesses, is usually given between six and eight weeks of age, with a second dose following between nine and ten weeks. A third dose is given between twelve and fourteen weeks, alongside the anti rabies vaccine, and a final booster completes the series from sixteen weeks onward. After that, the combination vaccine and rabies are both repeated yearly for life. For cats that go outdoors or live in multi cat households, we may also discuss an additional vaccine based on their individual risk and lifestyle.

Two rules we do not bend on

There are two things we will never compromise on, regardless of how eager a new pet parent is to stay on schedule. The first is that we do not vaccinate a sick puppy or kitten. Vaccines work by prompting the immune system to respond, and an animal that is already unwell, running a fever, or dealing with diarrhoea does not need that added stress on top of whatever else their body is handling. We will always postpone until they have properly recovered, even if that means a short delay to the overall schedule.

The second is that we deworm before vaccinating, not after. Worms can weaken a young animal's immune system, which means a puppy or kitten carrying worms may not build full protection from a vaccine even if the dose itself is administered correctly and on time. We typically recommend deworming seven to ten days before a vaccination visit, so the immune system is not trying to fight off worms and build vaccine protection at the same time.

What to expect after a vaccine

Most puppies and kittens tolerate vaccines well, and the reactions we do see tend to be mild and short lived, generally settling within a day or two without any intervention needed. A slight fever, reduced appetite, mild tiredness, or small temporary swelling where the injection was given are all common and not usually anything to worry about. Call your vet, however, if you notice repeated vomiting, facial swelling, difficulty breathing, or a puppy or kitten who seems significantly unwell rather than just mildly off, since those particular signs point toward a more serious reaction that needs prompt attention rather than a wait and watch approach.

Common myths worth clearing up

A few misconceptions come up often enough that they are worth addressing directly. Some owners assume that because their pet stays indoors, vaccines are not really necessary, but viruses travel easily on shoes, clothing, and through contact with other animals, so an indoor lifestyle does not mean zero risk. Others believe that once the puppy or kitten series is finished, no further vaccines are needed, but protection fades over time without regular boosters, which is exactly why yearly vaccination remains part of your pet's care for their entire life rather than a one time event. There is also a common belief that street dogs and cats somehow need different or fewer vaccines than pets who live indoors, but every dog and cat is equally at risk from the same illnesses, regardless of breed, background, or where they happen to sleep at night.

The TruVet takeaway

The vaccination schedule looks detailed because timing genuinely affects how well it works, not because we enjoy making things complicated. Missing a dose by a week or two is not usually a crisis, but building the full series on schedule, with deworming done ahead of it, gives your puppy or kitten the strongest possible start in life. If you are ever unsure where your pet stands in the schedule, bring your vaccination card to your next visit and we will map out exactly what is due and when.
