If she's had multiple distemper vaccines and isn't mounting a response, I'd call her a "non-responder", hope she has cellular immunity and just not bother again.
Have you thought about contacting a veterinarian well versed with titers (ie. Dr. Ron Schultz or Dr. Jean Dodds themselves) to see what their recommendations are?
Interesting side note - Two of my three didn't respond to the distemper vaccine, yet their parvo titers were sky high. (They were vaccinated as puppies and their titers were checked when they were roughly a year old).
YorkieMother - Where did you hear that titers are unreliable?
The vaccine isn't a sure thing either (obviously, since Ellie and my kids have all been vaccinated and didn't respond well), at least with titers you have more of an idea how their system is responding instead of automatically assuming they're protected. |
