For those of you who choose to do titers, do you do it annually?? Mayzie is due for her annual examand according to the vet her DHLLP vaccine. Last year, I declined the vaccine and instead had a titer done (after reading about vaccinations on this forum and other sites), which showed that she did not need the vaccine. Unfortunately, titering (at least at my vet) is much more expensive than vaccinating. I believe that if I do the titers again, they will show she doesn't need the vaccine and I'll spend $150 to find that out. I do plan on doing her annual exam either way, but do I need to do the titer test again this year?
