Which Vaccinations Does My Dog Need?
Core vaccines protect every dog; the rest depend on where your dog goes. Why the final puppy dose at 16 weeks matters more than the number of doses.
Your dog needs four core vaccines: distemper, parvovirus, canine adenovirus and rabies. Beyond those, leptospirosis and kennel cough are sensible for most dogs in Bengaluru, and the rest depends on where your dog actually goes. The importance of dog vaccinations is not a matter of opinion for this particular group of diseases. Distemper and parvovirus still kill unvaccinated puppies in this city, and rabies is almost always fatal once clinical signs appear, in dogs and in people alike. This article covers which vaccines are core and which are optional, the puppy schedule and why the age of the last dose matters more than the number of doses, how long each vaccine lasts, what a normal reaction looks like, and what to do if your dog's cover has lapsed.
What to Know The core vaccines for every dog are distemper, parvovirus and canine adenovirus, with rabies added as core anywhere rabies circulates, which includes all of India. Puppies start at 6 to 8 weeks and continue every 2 to 4 weeks, with the final dose at 16 weeks of age or later. The age of that last dose matters more than the total number given. Core protection then lasts three years or more, while leptospirosis and kennel cough need annual attention. Safety point: if a vaccinated dog bites a person, the bite still needs same-day medical assessment and human post-exposure treatment. Vaccinating the dog does not remove that requirement.
Which Vaccines Does Every Dog Need?
Vaccines fall into two groups, and the distinction is more useful than any list of brand names.
Core vaccines protect against diseases that are severe, widespread and capable of reaching any dog whatever its lifestyle. Every dog should have them, including dogs who rarely leave a flat. Non-core vaccines protect against diseases where risk depends on circumstances: where the dog walks, whether it boards, whether it swims, whether rats live near the kitchen bins.
| Vaccine | Protects against | Status in India | Notes |
|---|---|---|---|
| Canine distemper virus (CDV) | Distemper | Core for every dog | Neurological damage in survivors is often permanent |
| Canine parvovirus (CPV-2) | Parvoviral enteritis | Core for every dog | Virus persists in soil for months; puppies worst affected |
| Canine adenovirus (CAV-2) | Infectious canine hepatitis | Core for every dog | One vaccine covers both the liver and respiratory forms |
| Rabies | Rabies | Core, and usually required by law | Almost always fatal once signs appear; proof needed for most pet licensing |
| Leptospirosis | Leptospirosis | Non-core, advised for most Bengaluru dogs | Monsoon water and rodent urine raise risk; infects people too |
| Bordetella and parainfluenza | Kennel cough | Non-core, situational | Needed before boarding, daycare, grooming or shows |
In most of Europe and North America rabies sits in the non-core group. In India it does not. Rabies circulates continuously in the street dog population, India carries a large share of the world's human rabies deaths, and almost all of those exposures trace back to dogs. A rabies vaccine for a pet dog in Bengaluru is simultaneously protection for the dog, protection for your household and a legal document.
These vaccines usually arrive combined in a single injection, labelled something like DHPPi or DHPPiL, with rabies given separately. The letters refer to the components, so the combination you are offered will not always match the combination the dog actually needs. Ask which diseases are in the syringe rather than which product is being used.
Some components have little to recommend them. Canine coronavirus vaccine is not advised by international guideline groups, because the enteric disease it targets is mild and self-limiting in most dogs and the vaccine has not been shown to prevent meaningful illness. Giardia vaccine sits in the same category and has largely fallen out of use. If either appears on a quotation, ask what it is for and what benefit is expected from it.
What Is the Right Puppy Vaccination Schedule?
The schedule below is the one supported by current international guidance. Exact dates shift depending on the product used and the puppy's history, so treat it as the shape rather than the law.
| Age | What is usually given | Purpose |
|---|---|---|
| 6–8 weeks | First dose of combined core vaccine (DHPPi) | First attempt to get past maternal antibody |
| 10–12 weeks | Second dose of combined core vaccine | Covers puppies whose maternal antibody faded later |
| 12 weeks or older | Rabies, first dose | Earliest age at which rabies vaccine reliably works |
| 14–16 weeks | Final dose of combined core vaccine | The dose that actually matters most |
| 14–16 weeks | Leptospirosis, second dose if started earlier | Bacterin vaccines need two doses to work |
| 6–12 months | Booster of core vaccines and rabies | Catches any puppy who did not respond earlier |
| Every 3 years after | Core vaccines | Distemper, parvovirus and adenovirus only |
| Annually after | Rabies, leptospirosis, kennel cough | Shorter duration, or required by licence and law |
A puppy should be dewormed and in reasonable condition before the course starts. Vaccination is an ask of the immune system, and a puppy carrying a heavy roundworm burden, or one that is thin and dehydrated after a bout of diarrhoea, is not in a good position to answer. That does not mean postponing indefinitely. It means treating the worms, getting the puppy eating, and vaccinating a week later rather than skipping the appointment altogether.
Cold chain deserves a mention here, because it is where a technically correct schedule quietly fails. Vaccines must be held between 2 and 8 degrees Celsius from manufacture to injection. A modified live vaccine that has been left in a hot vehicle, or carried across the city on a scooter in April heat, may look identical and do nothing at all. Buying vials from a shop and carrying them home is a false economy, and a puppy that went through the full course with warm vaccine is, immunologically, an unvaccinated puppy.
Why Does a Puppy Need Several Doses Rather Than One?
Most owners assume the series works by building up, with each dose adding a layer. That is not what is happening, and the real explanation changes how you read the schedule.
A newborn puppy receives antibodies from its mother through the first milk. Those maternally derived antibodies protect it for a few weeks, then fade. While they are present at high levels they also block vaccine from working, because they neutralise the vaccine virus before the puppy's own immune system registers it. The vaccine is not harmful in that situation. It is simply wasted.
The problem is that nobody can tell by looking when a given puppy's maternal antibodies drop below the blocking level. In one litter it happens at six weeks. In another, from a bitch with a strong antibody response, it is still blocking at fourteen. There is also a gap in the middle where maternal antibody is too low to protect the puppy against real parvovirus but still high enough to interfere with vaccine. That window is where most parvo cases in vaccinated-but-not-finished puppies come from.
The series is a net rather than a staircase. Each dose is an independent attempt to catch the moment the window opens. This is why the final dose at 16 weeks of age or later is the one that counts: by that age maternal antibody has gone in essentially all puppies, so that dose almost always takes. A puppy given four doses finishing at 12 weeks is less reliably protected than a puppy given three finishing at 16.
That single fact also answers the most common question asked in the consulting room. A puppy is not covered after the first injection. It is not covered after the second. Treat it as protected roughly one to two weeks after the final dose of the series, and plan your outings accordingly.
Socialisation still matters, and the answer is not to keep the puppy indoors until four months old. The behavioural cost of a sealed-off puppyhood is real and lasts for life. A reasonable compromise: from about a week after the first dose, carry the puppy, use clean private terraces and homes, and allow contact with known adult dogs whose vaccinations are current and whose health you can vouch for. Hold off on public parks, pet shop floors, roadside verges and group classes until a week or two after the final dose.
Which Non-Core Vaccines Are Worth Having in Bengaluru?
Non-core does not mean unimportant. It means the decision depends on the dog in front of you.
Leptospirosis is the one I would discuss with almost every dog owner in this city. The bacteria are shed in the urine of rodents and of infected dogs and cattle, survive well in warm standing water, and enter through broken skin or mucous membranes. Monsoon turns much of Bengaluru into exactly the environment they prefer. Dogs that walk through puddles, drink from roadside water, swim in lakes, or live where rats are active are genuinely exposed. The disease damages kidneys and liver and can kill. It also transmits to people, which puts your household in the picture alongside your dog.
Two things to be clear about with leptospirosis vaccine. It needs two doses two to four weeks apart the first time, because a single dose of a bacterin does not produce useful protection. And it covers specific serovars, not every strain in existence, so a vaccinated dog that becomes unwell with fever, vomiting or yellow gums after monsoon exposure still needs veterinary attention and still needs leptospirosis considered.
Kennel cough vaccine is a lifestyle decision. The vaccine covers Bordetella bronchiseptica and canine parainfluenza virus, which together account for most cases. If your dog boards when you travel, goes to daycare, visits a groomer, attends classes or shows, or mixes regularly with unfamiliar dogs, it is worth having. Most boarding kennels require it. Give it at least a week before the stay, because immunity takes several days to establish and a vaccine given on the morning of drop-off has done nothing yet.
Kennel cough vaccine reduces severity and shortens illness rather than guaranteeing a cough-free dog. Owners who expect absolute prevention feel cheated when their dog comes home from boarding with a cough. A vaccinated dog that coughs usually coughs less, for fewer days, and with less risk of the infection descending into the lungs.
Canine influenza and Lyme disease vaccines are sometimes requested by owners who have read overseas advice. Neither disease is an established problem in India and neither vaccine is routinely indicated here.
How Long Does Each Vaccine Last, and Is an Annual Booster Needed?
Here is the misconception that costs Indian dog owners the most money and the most unnecessary injections: the belief that every vaccine needs repeating every twelve months.
That was standard advice decades ago, before duration of immunity was properly studied. It is no longer what the evidence supports for the core modified live vaccines. Distemper, parvovirus and adenovirus vaccines produce protection lasting at least three years in the great majority of adult dogs, and often considerably longer. Repeating them annually adds cost and injections without adding protection.
Three groups behave differently, and the chart above separates them.
Core modified live vaccines last three years or more. After the booster at six to twelve months of age, distemper, parvovirus and adenovirus can reasonably move to a three-yearly interval. Your dog should still have an annual health examination, which is the genuinely valuable part of the yearly visit and the reason the appointment should not be dropped.
Rabies follows the product licence and the law, not the biology alone. Some rabies vaccines are licensed for one year and some for three. Municipal rules in many Indian cities, Bengaluru included, expect proof of current rabies vaccination for pet dog licensing, and that proof is defined by the licence period printed on the vial. Where the law says annually, vaccinate annually.
Leptospirosis and kennel cough genuinely need repeating every year, because protection from both is short-lived. Dogs at high leptospirosis risk, such as those swimming in lakes through monsoon or living with a rodent problem, are sometimes vaccinated every six months. That is a decision to make with your vet rather than a default.
What Side Effects Should I Expect, and What Is an Emergency?
Most dogs show nothing at all. Of those that do react, the overwhelming majority have something mild that passes within a day or two. The table separates what to expect from what needs a phone call.
| What you see | Timing | What it means |
|---|---|---|
| Quiet, sleepy, slightly off food | Within 24 hours, gone by 48 | Normal immune response; let the dog rest |
| Sore spot or small firm lump at the injection site | Days to a few weeks | Normal; see a vet if it grows, weeps or persists beyond a month |
| Mild fever, a little shivering | First 24 hours | Normal; recheck if the dog is still unwell on day two |
| Vomiting or diarrhoea once | First 24 hours | Usually mild; call if it repeats or the dog stops drinking |
| Swollen face or muzzle, hives, intense itching | Minutes to a few hours | Allergic reaction; needs treatment the same day |
| Collapse, pale gums, laboured breathing, repeated vomiting | Usually within an hour | Anaphylaxis; this is an emergency, go straight to a vet |
Anaphylaxis after vaccination is rare but it is real, it is fast, and it is treatable when it is caught. For that reason it is sensible to stay near the clinic or at least contactable for the first half hour after any vaccination, particularly the first one a dog has ever had and particularly in small-breed dogs, where reactions are reported more often. If your dog has reacted before, say so before the needle comes out rather than after. Pre-treatment, splitting vaccines across separate visits, or dropping a non-essential component are all options once we know.
Reactions are also reported more often when several vaccines are given on the same day. In a healthy puppy this is usually unproblematic and the convenience is worth it. In a small adult dog with a history of a previous reaction, spacing rabies and the combined vaccine two weeks apart is a reasonable adjustment.
A lump that is still present after a month, or one that is growing, hard or attached to deeper tissue, should be examined rather than watched. The great majority turn out to be nothing of consequence. The point of looking is the minority.
What If My Dog's Vaccinations Have Lapsed?
Lapsed vaccination is the single most common scenario we see, and it causes far more anxiety than it should. A dog that is eight months overdue has not reverted to the immune state of a newborn.
For an adult dog with a documented history of a completed course, a single dose of the core vaccine usually restores protection. There is no need to start the puppy series again, however long the gap. The immune memory from the original course is still there; the dose reminds it.
For a dog with no reliable history, which includes most rescued street dogs and many purchased puppies whose cards were filled in optimistically, the dog is treated as unvaccinated. For the core modified live vaccines a single dose in an adult is generally enough, although many vets give two doses two to four weeks apart where the dog's age is uncertain and it could still be young enough for maternal antibody to matter. Leptospirosis always needs two doses, whatever the dog's age.
Lapsed rabies is the one to treat as urgent rather than as housekeeping. Book the appointment this week, not next month. In a rabies-endemic city, a gap in rabies cover is a gap in your household's protection as well as your dog's, and the legal status of the vaccination certificate also lapses with it. Licensing rules differ between municipalities, and a dog that is substantially overdue may be recorded as newly vaccinated rather than as continuously covered. Check what your local rules ask for before you need the certificate in a hurry.
Keep the vaccination card. Photograph both sides and store it somewhere you can find it from your phone. You will need it for boarding, for pet licensing, for any travel, and in the unpleasant event that your dog bites someone and the question of its rabies status is asked by a doctor who needs an answer in the next few minutes.
Can a Dog Be Too Old, Too Young or Too Unwell to Vaccinate?
Age by itself is almost never a reason to stop vaccinating, and this is where a lot of well-meant advice goes wrong.
An elderly dog's immune system responds less briskly than a young one's, which is an argument for maintaining cover rather than abandoning it. A thirteen-year-old dog that stops having rabies vaccination because it "hardly goes out" is a thirteen-year-old dog with no rabies protection in a rabies-endemic city, and it still goes to the gate when the bell rings. Core vaccines can often move to the longer three-yearly interval or be guided by titre testing, but rabies continues.
The genuine reasons to delay or modify are specific:
- Current illness. A dog with a fever, active vomiting, or an untreated infection should be treated first and vaccinated once recovered. The exception is a potential rabies exposure, which is a conversation to have with a vet immediately rather than a decision to make at home.
- Pregnancy. Modified live vaccines are generally avoided in pregnant bitches. Vaccination is best completed before mating, which also gives the puppies better maternal antibody.
- Immunosuppressive treatment. Dogs on chemotherapy or significant doses of steroids or other immune-suppressing drugs may respond poorly, and modified live vaccines are usually avoided. Timing around the treatment cycle needs planning with the treating vet.
- A previous severe reaction. A documented anaphylactic reaction changes the calculation. It rarely means no vaccination ever, but it means a planned approach rather than a walk-in appointment.
- A diagnosed immune-mediated disease. Dogs with conditions such as immune-mediated haemolytic anaemia need an individual decision, weighing disease risk in their environment against the small possibility of destabilising the condition.
Note what is not on that list. Mild skin allergy, a well-controlled chronic condition, old age, being a small breed, and having had a sleepy afternoon after the last vaccine are not reasons to skip core vaccination. If you have been told otherwise, book an examination and have the reasoning explained in writing, because the diseases on the other side of this decision are not mild.
Do Titre Tests Replace Boosters?
Titre testing measures antibody in a blood sample and tells you whether the dog currently has detectable protection against distemper, parvovirus and adenovirus. A clear positive result for those three is good evidence that a booster is not needed yet.
The limits matter as much as the use. A low or negative titre does not always mean an unprotected dog, because immune memory can persist without circulating antibody being measurable, so a negative result needs interpreting rather than acting on blindly. Titres are not meaningful for leptospirosis or kennel cough, where protection does not track antibody in a useful way. Rabies titres are used for international travel paperwork. They do not override a legally required booster.
Cost is the practical consideration. In many cases a titre test costs more than the booster it might save, which makes routine testing hard to justify for a healthy dog. Where it earns its place is in a dog that has had a significant vaccine reaction, where the question is whether this particular injection can be safely avoided this year. In that situation it is a genuinely useful test, and worth asking about.
Frequently Asked Questions
Which vaccinations does my dog need?
Distemper, parvovirus and canine adenovirus are core for every dog worldwide, and rabies is core everywhere rabies circulates, which includes all of India. Leptospirosis and kennel cough suit most Bengaluru dogs that walk outdoors, swim or board. Anything beyond that depends on travel and lifestyle, so the final list is a conversation with your vet.
When should a puppy have its first vaccination?
The first dose of combined core vaccine is usually given between six and eight weeks of age, with further doses every two to four weeks after that. Rabies is given from twelve weeks. Deworm the puppy and make sure it is eating and in reasonable condition before starting, but do not postpone the course for weeks.
Can my puppy go outside before the course is finished?
Public parks, pet shops and roadside areas should wait until one to two weeks after the final dose at sixteen weeks or later. Carrying the puppy, using clean private homes and terraces, and meeting known fully vaccinated adult dogs is reasonable from a week after the first dose. Early socialisation matters too much to skip entirely.
Does my dog need a rabies booster every year?
Some rabies vaccines are licensed for one year and others for three, so the interval follows the product used and the local rules. Municipal pet licensing in Indian cities generally expects proof of current rabies cover, defined by that licence period. Where annual vaccination is required, vaccinate annually and keep the certificate accessible.
Is my indoor dog really at risk from parvovirus?
Parvovirus survives in soil and on surfaces for months and resists many ordinary disinfectants, so it travels indoors on shoes, wheels and hands without a dog being involved at all. A puppy that has never met another dog can still develop parvoviral enteritis. Indoor life lowers exposure; it does not remove the need for core vaccination.
What should I do if my vaccinated dog bites someone?
Wash the wound immediately with soap under running water for several minutes, then send the person for medical assessment the same day. Human post-exposure treatment is decided by a doctor, not by the dog's vaccination card. Take the card along, keep the dog confined and observed for ten days, and tell your vet what happened.
Are side effects after vaccination normal?
Mild tiredness, a sore injection site, slightly reduced appetite or a small temperature rise in the first day or two are common and need nothing beyond rest. Swelling of the face, hives, repeated vomiting, pale gums or difficulty breathing are different. Those usually start within an hour and need a vet straight away.
Next Steps
If your dog is overdue for rabies, or your puppy has not had its final core dose yet, treat that as this week's task rather than next month's. If your dog is unwell after a vaccination with facial swelling, hives, repeated vomiting, pale gums or laboured breathing, go to a vet immediately and do not wait to see whether it settles. A bite to a person needs the wound washed under running water and the person assessed by a doctor the same day, whatever the dog's vaccination status.
If nothing is urgent, bring the vaccination card to your dog's next annual examination and go through it properly. The useful questions are which diseases are actually in the combined injection, whether the core interval can move to three years, whether leptospirosis belongs on the list given where your dog walks and swims, and whether kennel cough is needed before your next trip. Most dogs end up with fewer injections and better cover once the schedule is looked at honestly.
Our team can review your dog's history, set a schedule that fits how your dog lives in this city, and handle the paperwork for pet licensing, boarding or travel. Book an examination and bring the card, or a photograph of it, and we will work out what is genuinely needed and what has been going in out of habit.
