Good question...I found 2 websites for you that has some good information on a career as a Vet...I copied and pasted in the information about education requirements from one of them below. Good luck!
To become a veterinarian one must earn a Doctor of Veterinary Medicine (D.V.M. or V.M.D.) degree from an accredited college of veterinary medicine. Although many schools admit applicants who don't have a bachelor's degree, having one will increase your odds of getting accepted. There is keen competition for entry into this four year program.
