Thanks so much Kris.
Inquiring minds need to know these things.
Now for more questions. Dr. Schultz says an antibody negative dog should be revaccinated for CDV. How low can the titer go before needing to do this? 1:0? 1:1? Then I am reading that Dr. Dodds says a dog vaccinated after the immune system is fully mature doesn't need revaccination but then why are we titering? Why recommend titers when it is thought that the DOI is lifelong? It just seems a bit confusing to say yes we should titer and vaccinate when the titers are low and then at the same time say that if they are vaccinated (MLV) after 6 months, they never need to be again.

And then I am hearing that Dr. Schultz thinks these things last for life but says if there is a very low CDV titer, revaccinate. How can it go both ways?
What are we missing?
