At about what age do maternal antibodies typically provide protection in puppies?

• A. 2 weeks
• B. 4 weeks
• C. 8 weeks
• D. 12 weeks

Answer: (B)

Maternal antibodies transfer to puppies through colostrum and provide passive immunity during the early weeks of life. They protect puppies as they rely on this early defense, but these antibodies decline as the puppy’s own immune system ramps up. For most puppies, this protective window spans roughly the first 6–8 weeks and can extend up to about 12 weeks, which is also why vaccination is typically started around 6–8 weeks to ensure the vaccine works once maternal antibodies are waning. Among the given ages, around 8 weeks is the typical point when maternal antibodies are still providing protection but starting to fade, aligning with common vaccination timing. Earlier ages (2–4 weeks) are usually too soon for reliable protection as the antibody levels may be both high and variable, and later (12 weeks) is when protection is often already decreasing.
