Hi.. Good Day.. I Just Want To Ask, I Was

Hi.. Good Day.. I just want to ask, i was bitten by dog last march 23, 2016, i finished all my scheduled shot, my last injection was on april 3, 2016. Today (may 12, 2016) i was bitten again by our dog.. And i went again to the hospital where i got my shots..they said that, i don't need to be injected again.. since my last shot was only last month.. I just want to confirm if they are right..

Thank you.
