Dog Titre TestingThe protection from vaccinations for leptospirosis does not last a long time and we advise yearly booster vaccinations against this disease. However the protection against the other diseases lasts longer, but it is not always for a lifetime. Therefore we recommend a ‘booster’ for these diseases every three years. Kennel cough should be vaccinated against if your dog is in contact with other dogs regularly (e.g. dog shows as well as going to kennels or travelling). Rabies is required under the PETS travel passport scheme and is a legal requirement to travel abroad.
Each vaccination and duration of protection varies from each individual dog and many dogs can have sufficient protection against one or more of the diseases at the point the next booster is due. If they still have sufficient protection then potentially vaccination may delayed for that year. It is possible to blood test against parvovirus, distemper and hepatitis to measure antibody levels that will indicate whether your dog has a protective levels of antibodies against these diseases. However there is no such test for leptospirosis or kennel cough and therefore we recommend annual booster vaccinations to protect against these.
From previous studies regarding vaccinating and immunity, after four years after the last booster vaccination a third or more of dogs tested had a negative result to one or more of the three diseases, meaning vaccination is needed. This is why we vaccinate against Parvovirus, Infectious Canine Hepatitis and Distemper on a three yearly basis. In the case where your dog needs a vaccine against one disease and not all three, your dog would need to be vaccinated against all three against as the viral components are mixed together to make up the vaccination preparation.
In some cases we can gain false negative and false positive results on titre tests. False negative are not too important, however false positive can lead you to believe your dog is immune when they are not and therefore would not receive a vaccination and not be protected. There are in-house titre tests as well as external laboratory titre testing available for the veterinary market.
We offer titre testing at Milton Keynes Veterinary Group, however this is a test that needs to be ordered in and therefore we need to know in advance of your appointment. Usually titre testing works out more expensive than the vaccination alone. Vaccinations are safe and effective, and a substantial proportion of dogs that are titre tested can have a negative result to at least one disease and therefore a full vaccination is required (we cannot vaccinate against just one of the diseases due to the vaccination preparation). We regard antibody-titre testing as a useful resource, however comparatively poor value for money.
