Puppy Vaccine Schedule: Why Starting at 8 Weeks Matters

Puppy vaccines often begin around 8 weeks of age, with boosters every 2–3 weeks for a total of 3 booster visits in many cases. One of the most important vaccines in that early series is the parvo vaccine, because parvovirus can cause severe and sometimes life-threatening illness in puppies. Staying on schedule is one of the best ways to build protection early in life.
