If the pup already has antibodies administering a second vaccine will have absolutely no immunizing effect. You can't immunize an already immunized pup. So in this case a titer is a useful tool.

Once a dog has a positive titer, he is considered protected for life. This means he no longer requires more vaccinations (most of the core vaccines have been shown to protect dogs for 7 to 15 years). If the dog doesn’t require any other vaccinations, then why are the titers being repeated?

“The patient receives no benefit and may be placed at serious risk when an unnecessary vaccine is given” says Dr. Ronald Schultz. ”Few or no scientific studies have demonstrated a need for cats or dogs to be revaccinated.” Clearly, not only repeating a vaccination, but repeating a titer is unnecessary. Although repeated vaccinations place your pet at risk, repeated titers place your pocketbook at risk.
