Final answer:
When a vaccinated dog is exposed to the rabies virus, it will have an immune response and be able to fight the virus.
Step-by-step explanation:
When a vaccinated dog is exposed to the rabies virus, the dog will most likely have an immune response and will be able to fight the virus. Vaccination stimulates the dog's immune system to produce antibodies that can recognize and neutralize the rabies virus if the dog is exposed to it. This immune response allows the dog to effectively combat the virus and prevent the development of the disease.
