The Time Duration of the Rabies Vaccine in Dogs The health concern of domestic animals such as dogs is an ongoing concern for families. According to law, the rabies vaccine is required to help remove the deadly threat from dogs. For example, a dog who is exposed to the wildlife could easily return back carrying the rabies virus, putting themselves as well as their human family at risk. The rabies vaccine in Austin is easily available at the vet clinics. A three-year shot will approximately cost around $35 to $50, depending on the vet clinic. Previously, for many years the standard rabies vaccine schedule was to vaccinate the dogs annually without many options for specifics or schedules.
