After completing the initial DHP series, how often should a booster be administered?

• A. Every year.
• B. Every 3 years.
• C. Every 5 years.
• D. Every 2 years.

Answer: (B)

After the puppy series, the goal is to maintain long-lasting protection with a reasonable boost interval. A booster is given at about one year of age to ensure immunity once maternally derived antibodies wane. After that, most healthy adult dogs receive boosters for the DHP vaccines every three years, because studies show durable protection lasting at least that long for these core vaccines. Some dogs in high-risk environments or with certain health concerns might need more frequent boosters, but the standard interval for the DHP core vaccines is every three years.
