Here at The Well Dog Place we are always talking about doing blood titer tests for Distemper virus, Parvovirus and Viral Hepatitis rather than over vaccinating. But many of our dog parents don’t really know what a titer test means. By definition, a blood titer is the largest dilution of blood that still has evidence of antibodies to a particular virus. But what does that mean?
How Titer Tests Work
Research has verified the titer dilution necessary to protect dogs from distemper, parvo or hepatitis. If your dog’s titer is lower than those recognized as protective, your dog needs a vaccination. If her titer is equal to or greater than the protective levels, vaccination is not necessary at the time.
It is recommended to repeat blood titers yearly for these infectious disease to find out when protection from them has ended and your dog needs a protective vaccination.
