This episode explains titre testing in dogs and cats, what the test measures, how it relates to vaccination, and when it can be used instead of giving a booster. It covers how immunity develops, why some pets don’t respond well to vaccines, how long immunity lasts, and the pros and cons of testing before revaccinating.
Podcast Summary: Understanding Titre Testing in Pets
- Titre testing measures antibodies in the bloodstream to determine whether a pet still has protective immunity against core diseases.
- Core diseases tested include parvovirus, distemper, and hepatitis in dogs, and panleukopenia plus the cat flu viruses in cats.
- Vets take a blood sample and either run an in-house test (about 40 minutes) or send it to a laboratory for detailed analysis.
- Most pets respond well to their puppy or kitten vaccines and may retain immunity for many years — sometimes five, seven, or even nine years.
- Some pets are “non-responders,” meaning they do not develop immunity after vaccination due to genetics, illness at the time of vaccination, or other factors.
- Titre testing can confirm whether these pets achieved immunity after their initial vaccine series.
- Titre testing is often recommended before giving the next scheduled vaccination, especially when using three-year vaccines.
- Revaccinating a pet that already has strong immunity offers little additional benefit and may slightly increase the risk of rare immune-mediated reactions.
- Allergic vaccine reactions (facial swelling, hives) are uncommon and usually mild; more serious immune-mediated diseases are rare but possible.
- Titre testing is not about being “anti-vax” — vaccination remains essential, but testing helps avoid unnecessary boosters when immunity is already adequate.
- Most annual vet checks remain important for overall health, even when vaccinations aren’t due.
- Titre testing allows for individually tailored vaccination plans based on a pet’s immunity rather than a fixed schedule.
