Your dog has a higher risk of getting it right now so I would avoid contact with your in-laws dogs. It's up to you on getting the vaccine. I don't give it. But my dog is not around a bunch of strange dogs
We've avoided contact with the infected dog, their other dogs, and their home, and made sure we all wash our hands/etc. when coming back from their home. It's been about 6 weeks so I think we're pretty much in the clear. The vet had recommended a second Bordetella but I don't think he gave me a reason why... If it seems the first is going to give him the immunization and the second wouldn't do anything aside from cost money, then I'd assume #2 isn't necessary.
So, rabies shot in a few weeks then finally done with the torture
I appreciate your help!
