Dog booster vaccinations: what's actually needed each year
“Annual booster” is a slight simplification. Some components are given yearly, others every three years — and the difference matters when a booster slips.

In short
The usual adult booster pattern
| Component | Typical interval | Notes |
|---|---|---|
| Leptospirosis | Every year | Bacterial; immunity is shorter-lived |
| Distemper | Every 3 years | Given at the yearly visit when due |
| Hepatitis (adenovirus) | Every 3 years | Usually combined with distemper and parvo |
| Parvovirus | Every 3 years | Combined vaccine |
| Kennel cough (Bordetella) | Every year | Separate vaccine; often required by kennels |
| Rabies | Per product, often 3 years | Only needed for travel |
Exact intervals depend on the vaccine brand your practice uses and your dog's lifestyle and risk. Your vet decides the schedule; this is the general UK pattern.
What a lapsed booster actually means
There is no single cut-off. A booster a couple of weeks late is normally given as planned. Once a dog is months overdue, many practices restart the primary course of two injections three to four weeks apart — which costs more and delays boarding, because facilities want full cover in place before arrival.
If you are unsure how overdue you are, the vaccination card date is the answer. If the card is missing, ask your practice for a vaccination history.
Proving boosters to kennels, daycare and groomers
- Most facilities want to see dates, vaccine names and the practice stamp
- Many require vaccination 7–14 days before arrival
- Kennel cough is frequently required separately from the core booster
- A clear photo is often accepted, but confirm before you travel
Never miss one again
Booster dates are easy to remember for the first year and easy to lose after that. Log the date on the day it is given, store a photo of the card with it, and set a reminder a month ahead so there is time to book. That is exactly what Pawfile does — for vaccinations, flea and worming treatment, insurance renewals and prescription expiry.
This is general information, not veterinary advice. Vaccination protocols vary by country, brand of vaccine and your pet's individual risk. Always follow the schedule your own vet recommends. Pawfile is an admin tool for keeping those records and reminders organised — it does not diagnose or treat.
Common questions
- Do dogs need booster vaccinations every year?
- Not every component is annual. In the UK, leptospirosis is usually boosted every year, while distemper, hepatitis and parvovirus are typically given every three years. Most dogs still see the vet yearly, because the leptospirosis component and the health check are annual.
- What happens if my dog's booster is late?
- A short delay is often fine and your vet will simply give the booster. If the lapse is long, the practice may advise restarting the primary course of two injections. Ring and ask rather than guessing — the answer depends on the vaccine used and how overdue you are.
- Is kennel cough part of the booster?
- Usually not. Kennel cough (Bordetella) is generally a separate intranasal or oral vaccine, given yearly and often required by kennels, daycare and some training classes.
- Do kennels accept a booster given last week?
- Many facilities require vaccination at least 7 to 14 days before arrival so immunity has time to develop. Check the specific kennel's policy before booking a last-minute appointment.
- How do I prove my dog's boosters are up to date?
- Your vaccination card or a vaccination history printout from your practice. Photograph it as soon as you leave the appointment so proof is on your phone when a kennel or groomer asks.
