Biomedical Science can open you up to other fields besides Vet School. Of course, you could also pursue other health professions such as Medicine, Dentistry, Physical Therapy, Pharmacy, Optometry, etc. You could also go into Lab Research or Biotechnology. You could decide to go into teaching Science subjects in schools and after-school programs. Overall, even though you majored in Biomedical Science, it doesn't preclude you from obtaining jobs that don't necessarily require a specialized degree. Plenty of positions merely ask for a Bachelor's Degree in any field and consider more importantly your experience in any kind of work (paid or volunteer) that is related to the position you're applying for.
