While you *can* take many of the individual courses required for veterinary school admission online through various platforms (like Coursera, edX, community colleges offering online courses, etc.), these individual courses won't combine to give you a "pre-vet degree." You'll need to earn a Bachelor's degree in a relevant field (biology, animal science, etc.) from a regionally accredited institution to apply to veterinary school. That Bachelor's degree program may or may not be entirely online, but the *degree* itself comes from a fully accredited university or college, not a purely online pre-vet program.
