Doctorate of Philosophy (Ph.D.) Veterinary and Animal Science is a 3 to 5-Years course at Veterinary College, Bangalore. A veterinarian can help relieve an animal that has experienced a traumatic injury or dealing with chronic illness. To become a veterinarian, a student must be good at problem-solving. Some detective work has to be done to evaluate each case. An animal obviously can’t explain what’s bothering them, a veterinarian has to figure out based on physical exam, lab tests, and owner’s comments.
