Spring has a funny way of making us feel productive. We swap boots for sneakers, we book the groomer, we start thinking about hikes… and a lot of pet parents get that annual reminder from the vet: “Time for boosters!”
Staying on top of your pet’s health is a great goal. But more isn’t always better, especially when we’re talking about vaccines.
At Creature Comfort Pet Emporium, we’re big believers in the first, do no harm approach. That means prevention and informed choices—so you can protect your pet without accidentally overdoing it.
Boosters: what they are (and what they do to the immune system)
A booster is an additional dose of a vaccine given after the initial series.
Each vaccination exposes the immune system to disease components, which triggers your pet’s immune system to produce antibodies. That’s the whole point—training the body to respond faster if it ever encounters the real disease.
But it’s also why it’s worth being intentional: every vaccine is an immune event.
“Annual boosters” aren’t one-size-fits-all
Instead of treating every yearly reminder like an automatic checklist, bring the conversation back to what actually matters:
-
What is my pet actually at risk for right now?
-
The length of vaccination protection depends on the disease, the type of vaccine used, and your pet’s immune system.
-
Request antibody titer tests (when appropriate) to determine if a booster is even necessary based on existing antibody levels.
Core vs lifestyle vaccines (simple way to think about it)
If you’ve ever felt overwhelmed staring at a list of vaccines, this framework helps:
-
Core vaccines are the “most pets, most places, most of the time” group—recommended because the diseases are serious and/or widespread.
-
Lifestyle vaccines are based on your pet’s real life: where you live, where you travel, and what your pet is exposed to.
Lifestyle factors that can change what your pet needs:
-
dog parks, daycare, training classes
-
boarding or grooming facilities
-
hiking in tick-heavy areas
-
traveling (even within Ontario)
-
multi-dog homes, foster dogs, frequent dog visitors
Your vet knows the medical side and local disease trends. You know your pet’s routine. Together, you can build a plan that makes sense.
Titers: check immunity before re-vaccinating
A titer test is a blood test that measures antibodies for certain diseases. In plain language: it can help show whether your pet’s immune system still “remembers” a vaccine.
Why pet parents like titers:
-
helps avoid unnecessary repeat vaccination
-
supports a more individualized plan (especially for sensitive pets)
-
provides peace of mind when you’re trying to balance protection with a “don’t overdo it” approach
Titers aren’t always the right fit for every vaccination booster, and they’re not used for every vaccine. But they’re a great conversation starter if your pet:
-
has had vaccine reactions in the past
-
has chronic inflammation/skin issues that flare easily
-
is older or medically complex
-
is already well-vaccinated and you’re trying to avoid “just in case” boosters
We’re not anti-vaccine. We’re anti-over vaccinating.
Vaccines have saved countless animal lives.
We’re pro “make choices that make sense.”
Over-vaccinating can mean asking the immune system to do extra work it may not need to do. For some pets, that may show up as:
-
feeling crummy for a day or two
-
immune stress or inflammation
-
reactions that make future vet visits harder for everyone involved
If your dog already struggles with itchy skin, chronic ear issues, digestive upset, or recurring inflammation, it’s worth taking a more tailored approach instead of defaulting to automatic annual boosters.
Spring check-up = the perfect time to advocate (without being “that person”)
Being your pet’s advocate doesn’t mean arguing with your vet.
It means showing up educated, calm, and clear about what you want for your pet.
Here are a few respectful, helpful things to say/request:
-
“Please walk me through which vaccines are core for my pet and which are lifestyle-based.”
-
“Based on where we live and what we do, what is my pet’s actual exposure risk?”
-
“For vaccines where it’s appropriate, I’d like to request antibody titer testing before re-vaccinating.”
-
“I do not want multiple vaccinations given at the same visit.”
Why that last one matters:
-
it reduces the chance of stacked reactions
-
if a reaction does happen, it’s easier to assess which vaccine may have triggered it
-
it avoids putting unnecessary strain on the immune system all at once
And one more permission slip you might need:
If you’re ever in an appointment and feeling overwhelmed or undecided, it’s okay to say:
-
“I’d like more time to think about this information before making a decision.”
It is okay to say no if you aren’t sure it’s the best choice for your pet.
Don’t skip this: annual wellness bloodwork (including 4Dx testing)
Whether you’re a dog person or a cat person (or you’re living the multi-pet household dream), annual wellness bloodwork is one of the most useful tools we have for long-term health.
Why it matters:
-
it helps show how your pet’s organs are functioning
-
it provides a baseline you can compare to in future years (super helpful for diagnostics if values change)
-
it can catch concerning conditions early, so they can be addressed before they become bigger problems
And as part of that annual bloodwork conversation, request 4DX testing for your dog(s).
A 4DX test is commonly used to screen for:
-
heartworm disease
-
tick-borne diseases
Early detection of heartworm or tick diseases can be life-saving—and ticks are not a “summer-only” problem anymore.

You’re allowed to choose “check immunity first” when it’s appropriate.
