It’s no surprise to many disgruntled pet owners that many veterinary clinics rely on revenue from vaccines. Happily for the dogs, many vets have replaced vaccinations with titer testing. The problem with this is twofold: one, they are replacing yearly or triennial vaccination with yearly or triennial titer testing, and two, titers are expensive.
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?
