Oh, Holly, what a heartbreak! I'm so sorry you lost both of you dogs in such short order after vaccination. It's heartening at least to know you're taking their example forward to the benefit of all future animals you have a say in raising.
Be sure to be fully conversant in what titers can and can't tell you, so you don't make the common mistake so many do when the titer falls.
