Understanding Vaccination Requirements for Dog Boarding

Why Kennels Ask About Vaccinations Before Anything Else

Booking your dog's holiday care should feel straightforward, but sooner or later the question comes up: when was your dog last vaccinated, and can you send us the certificate? It is not a kennel being awkward for the sake of it. Boarding puts dogs from different households into close contact, sharing exercise areas, water bowls and kennel runs. That is exactly the environment where an unvaccinated dog poses a genuine risk both to itself and to every dog staying alongside it.

Most reputable boarding establishments in the UK will refuse a booking without proof of current core vaccinations. Knowing the requirements in advance means you can plan around them rather than scrambling for a vet appointment the week before you fly.

The Core Vaccines Your Kennel Will Expect

When a kennel asks for "up-to-date vaccinations", they almost always mean the core vaccines that protect against the following:

• Canine distemper — a serious viral disease affecting the respiratory, gastrointestinal and nervous systems.
• Canine parvovirus — highly contagious and often fatal, particularly in puppies and older dogs.
• Infectious canine hepatitis — caused by canine adenovirus, affecting the liver and sometimes the eyes.
• Leptospirosis — a bacterial infection spread through water and urine, which can also affect humans.

In practice these are usually combined in a single injection, often described as the "booster". In the UK, leptospirosis protection is commonly given as an L4 vaccine, covering four strains. Some vets use L2, which covers fewer strains, so it is worth checking which your dog has had if your kennel specifies L4.

Many kennels also require protection against kennel cough, a respiratory infection caused most often by Bordetella bronchiseptica and parainfluenza virus. This is not part of the standard core injection and usually needs to be requested separately, either as a nasal spray or an injection.

Why Kennels Are Stricter Than Your Vet's Booster Reminder

Your vet may be relaxed about a booster being a few weeks late, particularly for an older dog. A boarding kennel cannot be. Their insurance, licensing conditions and duty of care all point the same way, and a single infected dog can sweep through a full kennel block within days.

This is why most establishments will not accept:

• A vaccination that has lapsed, even briefly, until it has been restarted and completed.
• A handwritten note saying the dog "had its jabs" without a signed certificate.
• A puppy's first vaccination alone, without the full course completed.
• Kennel cough protection given too close to the stay date to have taken effect.

If your dog's booster has lapsed, the vet may need to restart the course from scratch, which means two injections two to four weeks apart, plus a further waiting period. That can easily add six weeks to your timeline, so check your records early.

Timing Your Vaccinations Around Your Trip

Vaccines need time to work. As a general guide, kennels ask that core boosters are given at least two weeks before the boarding date, and often prefer a month. The kennel cough vaccine typically needs a similar window, though some intranasal versions are accepted with as little as 72 hours' notice. Always confirm the exact rule with the specific kennel rather than assuming.

A sensible routine looks like this:

• Check your vaccination certificate as soon as you book your holiday.
• If anything is due within three months, bring the booster forward.
• Book the kennel cough vaccine at the same visit if your vet is happy to combine them.
• Leave a minimum of two weeks, ideally three, before check-in.
• Keep a photo of the updated certificate on your phone as a backup.

What Paperwork You Will Need

You will normally be asked to bring the original vaccination certificate, signed and dated by your vet. It should show the vaccine name, the date given, and the batch number. A card is preferable to a printout, although many kennels now accept a clear photograph or a digital record.

It also helps to have details of your dog's microchip number, any ongoing medication with dosage instructions, and your vet's practice address in case of emergency. Kennels that ask for all of this upfront are usually the ones who handle problems well, so treat the questions as a good sign.

If Your Dog Cannot Be Vaccinated

Some dogs genuinely cannot be vaccinated, for example those with certain immune conditions or a history of adverse reactions. In these cases, ask your vet whether a titre test is appropriate. This blood test measures existing antibodies and can show that protection is still present, which some kennels will accept alongside a letter from your vet.

Not all establishments will agree, and those that do may ask for additional precautions. It is worth ringing around early and being honest about your dog's situation rather than turning up on the day and hoping. A quick conversation now saves a stressful phone call the night before your holiday, and it gives your dog the best chance of a calm, well-protected stay.
