Dog vaccinated after breeding: Will puppies be deformed or aborted?

Updated On September 23rd, 2025

Pet's info: Dog | Poodle | Female | unspayed | 50 lbs

My dog was just vaccinated with a 5 way combo shot and a oral kennel cough vaccine. My boyfriend just informed me that on day 14 of her heat cycle she was with our male for 10 minutes alone. I'm really upset and worried about the health of the puppies if she is in fact pregnant. What are the possible side effects of these shots given to her 12 days after she could have mated? What are the odds of the puppies being deformed or aborted?

Hello, thank you for using Petco Pet Education Center, formerly Petcoach. The timing of Lucy's vaccinations will have no impact on her pregnancy. These vaccines are very safe, & do not cause any problems with puppies developing in utero. Take care.
