This will likely be the last post in this series, at least for now, but last doesn’t mean least. The potential use of titre testing to inform vaccination decisions is an important issue that drives a lot of questions. A titre (or titer for our American friends) is a measure of the level of antibodies…

Determining the optimal duration of treatment for infectious diseases in animals is an ongoing challenge. We typically have very little data to guide us, but lots of deeply ingrained habits and dogma about how to do it. The durations used for treatment of many infectious diseases in pets are longer than those used in comparable…

The veterinarian recommends a DAPP vaccine (distemper, adenovirus, parvovirus, parainfluenza), as well as vaccination for rabies and leptospirosis. After some discussion, the owner declines the lepto vaccine, but proceeds with the others. The next day, they call back after doing some reading…

Let’s face it, approaches to vaccination in companion animals are based partly on direct evidence, partly on extrapolation from other species, partly on expert opinion, and partly on “this is what we do because it’s what we’ve always done.” The evidence base for much of what we do is incomplete, and for a…
