If he is up to date on rabies vaccination, most of the shelters here will allow quarantine at your vet, sometimes at home. If they will allow it, move fast and get your dog out of the shelter.
Out of curiosity - which shelter is he quarantined at?
Clayton county animal shelter in georgia. The thing is i dont even have the recent papers for his vaccination. I recently not too long ago cancelled the optomus wellness plan at banfield because they almost killed my dog and only caref about money. So im not even sure if they have records anymore.
