Now, if his titers indicate that he needs to be vaccinated, he's given a combination of benadryl & dexamethasone IV.
Once a dog has had a high titer to a disease, a low titer means nothing except that the dog has not been recently exposed to the disease. It does not mean that he needs to be vaccinated.
A titer measures antibodies. Antibodies eventually wear out, but that does not mean that the memory cells that would produce the antibodies (if necessary) are gone. There is no test for that.
Studies have shown that distemper and parvo vaccines are effective for at least 7 years - meaning that the memory cells last at least that long. Some researchers believe the immunity is lifetime, but long enough studies have not been conducted to prove that. (Of course, manufacturers have no incentive to prove that you don't need to keep using their vaccines.)
The chances are extremely good that a previously vaccinated dog with a low titer (for diseases with MLV vaccines) gets nothing from additional vaccines (for those diseases) except an activation of the memory cells to produce antibodies. In other words, a memory cell workout and not an increase in immunity.
To up your chances of a high titer, visit a dog park a few weeks before the titer. That may provide a small disease exposure and result in a high titer.
I really question the need for Shooter to ever get parvo or distemper vaccines again. Rabies either for that matter, but a study to prove at least 7 years is ongoing for that disease.
I hope your vet doesn't keep using the same vaccine from the same manufacturer. Some dogs will react to ABC's vaccine, but not to XYZ's vaccine. The preservatives, for instance, can be the problem. The preservative Thimerosal contains mercury, so you really want to avoid that one - reaction or no reaction.
Are you putting the vaccine vial labels in Shooter's records? That may be your only record of exactly which vaccines Shooter receives.
