The American Animal Hospital Association updated its Vaccination Guidelines in September 2017. The guidelines include some important decision flow-charts about titer testing and how to respond to the results in a variety of situations. This is an important topic if you want to avoid over-vaccinating your dog. So, I figured it's a good time to talk about Clover's recent titer test results and about titer testing in general since it may be a new thing for you. This is a LONG post. Grab a snack.
