At what age should a puppy vaccination program begin?

• A. 4-6 weeks.
• B. 8-10 weeks.
• C. 6-8 weeks.
• D. 12 weeks.

Answer: (C)

Puppies begin vaccination when their maternal antibodies have waned enough for the vaccine to stimulate the puppy’s own immune response. This is typically six to eight weeks of age. Starting within this window allows the vaccine to be effective, whereas giving vaccines earlier (around four to six weeks) can be blocked by maternal antibodies, providing little protection. Waiting until twelve weeks leaves a period of vulnerability where the puppy is at risk before immunity is established. To ensure solid protection, vaccines are given in a series—first dose at six to eight weeks, with boosters every three to four weeks until about sixteen weeks. So, six to eight weeks is the appropriate starting point.
