We saw our Holistic Vet today and I asked about the "positive/negative" titer response for you.Dr Schultz says that Parvo and distemper have lifelong immunity though (the AVMA has published a journal saying something like 95% and 97% of dogs have immunity for 7+ years, which was the end of the challenge study, not that after 7 years they lose immunity), would you booster them anyway?
He also mentioned that in rare cases the dog does not respond to certain vaccines, but that if it didn't respond the first time, it's unlikely to respond to later vaccinations (for the same virus).
So my question is, are titers necessary? I guess what I'm concerned with is that they don't measure cell mediated immunity, so a negative titer doesn't mean your dog has no immunity. What do you do if your dog's titer is negative, if it doesn't necessarily mean your dog isn't protected?
This is where I'm confused.
Also, when and how often do you titer? I heard there are different titer tests, some more effective than others?
If your dog shows a positive titer test, is it really necessary to booster them again, even if at a later date, the titer is negative? Would they not have the cell mediated immunity? All a negative titer means is the body isn't actively fighting the virus, because it has told itself that the threat has been neutralized, not that it can't respond if challenged again.
Answer: When taking titers, ask your vet to do IFA testing at Antech Labs or through Dr. Dodds. This test will give a "YES or NO" reading.
Here is Dr. Dodds form for this: http://www.itsfortheanimals.com/Adobe/TEST_REQ_FORMandINSTRUCTIONS-2-12.pdf
Personally, our dogs are titered every 12 to 16 months for Parvo and Distemper. We probably check it more often than most because our dogs only had One Parvo and One Distempter vaccination (Holistic vet in agreement of this) when they were around 16 weeks old. They are now 5 & 7 years old and even after only one vacc of each, they are still FULLY covered. Proves Schultz and Dodds research!
BUT, like people, all dogs systems process things at different rates, so titers are important. For example, our female holds the Rabies antibodies so long, and her numbers are so extremely high, that our vet has had us give her homeopathic remedies a few times to combat the effects of it on her system.

Hope this helps!
