Veterinary education is the tertiary education of veterinarians. To become a veterinarian one must first complete a veterinary degree (i.e.: DVM, VMD, BVS, BVSc, BVMS, BVM, cand.med.vet, etc.).
Like veterinarians they are more involved in the medical side of animal care and not so much the observation or study. To be a vet tech you need to enroll in a veterinary technology program and to be a full fledged veterinarian you'll need both a B.S. in Biology and a Doctor of Veterinary Medicine (D.V.M.) degree. Biologists or zoologists are researchers who study animals. You would be less likely to have regular physical interaction with animals and not perform as much day to day care in this field but you would get to spend a lot of time observing them.
