Is it safe for my 9-week-old puppy to get the lepto vaccine early?
Updated on September 23, 2025
Pet's info: Dog | West Highland White Terrier | Female | unspayed | 2 months and 5 days old | 4 lbs
I believe my vet may have given my 9 week old puppy her 12 week shots. Is it harmful for a 9 week old Westie to receive the lepto vaccine with their puppy shots?

The vaccine manufacturer will typically make a recommendation about the age at which to start the vaccine, and there are some leptospirosis vaccines labeled for ages 9 weeks and older. Even if the vaccine was labeled to start later many veterinarians will start vaccines earlier than labeled for dogs at high risk for infectious diseases like those in shelters and do not seem to experience an increase in side effects.
