*pulls out her doggie vet card*
my boy had all this done last time
C3 = Distemper, Hepatitis, Parvovirus
C4 = C3 + Parainfluenza virus (viral component of "kennel cough")
C5 = C4 + BB (the bacterial component of "kennel cough" - Bordatella bronchiseptica)
so whatever that means!
i have him done for kennel cough because i bring home sick dogs for nursing back to health. to this day he still hasnt had kennel cough! woo!
