My dog just got anti rabies shot last sunday. Then my boyfriend was playing with our dog the next day after the vaccine and was accidentally bitten. Does he still need anti rabies shot? Our vet said that we don't need to just only anti tetanus. But last summer he already got the anti tetanus shot because he was bitten by a rat. Does the anti tetanus shot still effective until this day? And there was one scenario that my dog was outside and was barking angrily anf when we went out to look there was a cat. This happened before the anti rabies shot was given.
