Dog booster vaccinations: how often and what they cost
Dog vaccine boosters keep the protection from the puppy course topped up — typically a single visit a year costing £40–£60. But not every component needs boosting every year, and a lapsed schedule doesn't always mean starting from scratch. Here's how dog vaccinations booster schedules actually work.
Which vaccines need boosting, and how often
Leptospirosis immunity fades fastest, so that component is generally boosted yearly. The core viral protection (distemper, hepatitis, parvovirus) often lasts longer — many brands are licensed for three years — so in practice your dog may alternate between a "full" booster some years and a lepto-only booster in others. The practice tracks this against the specific brands they use, which is why schedules differ slightly between vets.
Missed a booster? Here's what actually happens
Life happens, and boosters lapse. A few weeks late is rarely a problem. Beyond a certain window — which varies by vaccine — the manufacturer's licence no longer guarantees a single booster will restore full immunity, so your vet may recommend restarting the two-injection primary course instead. That's the real cost of a long lapse: roughly double the price, plus a couple of weeks before full protection returns. If your dog is overdue, ring your practice and ask what their restart threshold is rather than assuming the worst.
Titre testing: the booster alternative
Some practices offer titre testing — a blood test that measures existing antibody levels before automatically re-vaccinating. It costs more than a booster, but for owners who'd rather not vaccinate unnecessarily it provides evidence either way. Note it works best for the core viral components; lepto protection is still generally boosted annually regardless.
Frequently asked questions
How often do dogs need booster vaccinations?
Leptospirosis boosters are generally yearly; the core DHP components are often licensed for three years. Your dog's schedule depends on which brands your vet uses — their record will show what's due when.
How much do dog vaccine boosters cost?
Annual boosters typically cost £40–£60 including the health check. That's cheaper than the puppy primary course since only one visit is needed.
What happens if my dog misses a booster?
A short delay is usually fine, but leave it too long and your vet may recommend restarting the primary course rather than a single booster — which costs more. If you've lapsed, ring the practice rather than guessing.
Is the annual booster appointment just an injection?
No — it includes a full health check, which is often where age-related issues get caught early. Many owners find the check-up the more valuable half of the visit.
