A titre test is a simple blood test that measures a dog or cat’s levels of antibodies to vaccine viruses (or other infectious agents). For instance, your dog may be more resistant to a virus whereas your neighbour’s dog may be more prone to it.
Titre’s accurately assess if your pet has protection to the so-called “core” diseases (distemper, parvovirus, hepatitis in dogs, and panleukopenia in cats), enabling vets to be able to judge whether a booster vaccination is necessary or not. Ask your vet whether they carry out this test, as it is available around Australia.
If your pet does not require a vaccine booster then your vet can issue you with certification that your animal is covered for the next 12 months. This is only necessary for proof of cover when boarding your animal etc.
