Some veterinarians use their experience to teach veterinary students about the profession. Some continue working as veterinarians and teach part-time at a college, university, or veterinary medical school. Others who have been practicing for years go into teaching full-time because the schedule is a lot easier, and they want to impart their love and knowledge of the profession to their students. Lots of opportunities exist for teachers at the nation's twenty-eight veterinary medical schools. Those specializing in advanced degrees are in even greater demand. Teachers can earn upward of $65,000 to start, and over $100,000 annually over time.
