SW, I'm so happy to hear that Timber is still doing well and glad to hear that you are going to get the thyroid test done.
I don't vaccinate my dogs anymore ...one is just over 6 yr old and the other will be 6 yr in July. I don't even titer them ....as MaxaLisa said, and my vet told me as well, those tests are inadequate.
Good luck with Timber's tests and looking forward to your update.
