I wasn't sure whether to include this with the other vaccination thread, but I think this is a bit different. My goldie is due to have his first booster vaccination. Last year when we got him, some dog trainers we met advised not to re-vaccinate, but to have a titer test done. The May edition of Dogs Today magazine has a long article about the dangers of annual vaccinations - it seems they are both unnecessary (as immunity persists from first puppy vaccinations for at least several years), but also dangerous (can cause life-threatening problems such as cancer, Addison's, aneamia). So I'm thinking of not re-vaccinating, but having a titer test done to establish his immunity level. Does anyone else do this, and if so, how do you deal with boarding kennels and anyone else who require annual vaccinations?
