If you're in high school, now's the time to start thinking about your future, especially if you plan to go to college. The steps you take right now can help you to get a head start on your eventual career. This is especially true if you want to become a veterinarian. Getting involved in veterinary internships while you're still in high school can open up opportunities for your future. If you thought you could only get veterinary internships during college, you were mistaken.
