Huey has always had the intranasal, but this year he got an oral liquid. When I asked, the vet said that they changed recently but did not elaborate. I am thrilled, since Huey always snotted out the intranasal as quick as it was given.
I found this on line:
Bronchi-Shield ORAL – First Oral Bordetella bronchiseptica Vaccine Approved for Use in Dogs
Veterinarians have a new, innovative vaccine choice available for protection from the primary pathogen of canine infectious respiratory disease (CIRD). The vaccine, Bronchi-Shield® ORAL from Boehringer Ingelheim Vetmedica, Inc. (BIVI), recently has been approved by the USDA for use in dogs. This vaccine is unique because it is the first live, avirulent Bordetella bronchiseptica vaccine licensed to be administered orally to dogs.
