So why, why, WHY do some vets still vaccinate pets every 3 years, or worse, every year?

When you do vaccinate, NEVER VACCINATE A LESS THAN 100% HEALTHY DOG, NEVER GIVE MORE THAN ONE VACCINE AT A TIME (AND NEVER, EVER A COMBO VACCINE). Insist on a 3 year rabies vaccination (vs a 1 year vaccine which is, ironically, the exact same thing).

Worth Repeating: NEVER VACCINATE A PET THAT IS NOT 100% HEALTHY
Any vaccine has the ability to kill or harm your pet. Work with your vet to make sure EVERY vaccination given to your specific pet is absolutely necessary. If your vet won't work with you or insists your pet is vaccinated every year, you might want to find a new vet.
