What courses do you have to take be a vet duke university?

Duke University doesn't have a veterinary school. To become a veterinarian, you would need to apply to and attend a veterinary school (such as North Carolina State University's College of Veterinary Medicine, which is relatively close to Duke). These schools have their own specific prerequisites and curricula. They generally require a significant amount of undergraduate coursework in biology, chemistry, and other related sciences. The exact courses will vary by school, so you need to check the admission requirements of each veterinary school you are interested in applying to.
