The Wildlife Society offers the Certified Wildlife Biologist credential, which requires a combination of education and professional experience.

Career Pathways After Graduation

Clinical Veterinary Medicine

The most direct path after earning a bachelor's degree in any of these majors is admission to a Doctor of Veterinary Medicine (DVM) program. Veterinary schools require specific prerequisite courses—typically including organic chemistry, biochemistry, animal nutrition, microbiology, and physics—which can be completed within any of the listed majors. However, animal science and biomedical sciences often map most efficiently to these requirements, with many courses already integrated into the major. The DVM program generally takes four years and leads to licensure as a veterinarian after passing the North American Veterinary Licensing Examination (NAVLE). Clinical practice can focus on small animals (dogs, cats), large animals (horses, cattle), exotic pets (reptiles, birds, small mammals), or mixed practice. Some veterinarians also specialize through internships and residencies in areas such as surgery, internal medicine, dermatology, or oncology.

Animal Research and Biomedical Science

Graduates with zoology or biomedical sciences backgrounds are well-suited for research positions in academic laboratories, government agencies such as the National Institutes of Health (NIH) or U.S. Department of Agriculture (USDA), and pharmaceutical or biotechnology companies. Roles may include research assistants, animal behavior technicians, or lab animal veterinarians (after completing a DVM and often a residency in laboratory animal medicine). The demand for research scientists with animal handling experience remains strong due to the continued reliance on animal models in drug development, toxicology, and disease research. Organizations such as the American Association for Laboratory Animal Science (AALAS) offer certifications that can significantly boost career prospects. AALAS certification levels—Assistant Technician, Technician, and Technologist—are recognized industry-wide and often lead to higher pay and advancement opportunities.

Wildlife Conservation and Environmental Policy

Wildlife biology and zoology majors often pursue careers with conservation NGOs, state and national parks, consulting firms, or federal agencies like the U.S. Fish and Wildlife Service. Conservation work may involve population monitoring, habitat restoration, environmental impact assessments, or policy advocacy. Roles such as wildlife biologist, conservation scientist, or environmental educator typically require a master's degree for advancement to supervisory or research-oriented positions. Some graduates also work as wildlife rehabilitators, helping injured or orphaned animals return to the wild. The Wildlife Society provides a job board and professional development resources for those entering this sector.

Veterinary Technology and Support Roles

Graduates of veterinary technology programs become credentialed veterinary technicians (RVT, LVT, CVT). They work alongside veterinarians performing medical tests, collecting samples, assisting in surgery, taking radiographs, and educating pet owners. Many technicians choose to specialize in areas such as equine nursing, dental technology, emergency and critical care, or anesthesia. Advanced education can lead to roles like veterinary technologist, practice manager, or veterinary surgical assistant. The National Association of Veterinary Technicians in America (NAVTA) offers resources for career development and specialty certification.

Animal Behavior and Training

Graduates with strong foundations in zoology or animal behavior—often offered as a concentration within zoology departments—can become applied animal behaviorists or certified trainers. These professionals work with zoos, shelters, animal rescue organizations, and private clients to modify problematic animal behavior or train service animals. Certification through the Animal Behavior Society (Certified Applied Animal Behaviorist, CAAB) or the International Association of Animal Behavior Consultants (IAABC) is highly regarded and often required for independent practice.

Essential Skills and Qualifications for Success

Regardless of the major selected, certain competencies are universal for success in animal-related careers. Students should actively develop these skills throughout their undergraduate studies:

  • Biological and physiological knowledge: Deep understanding of anatomy, organ systems, and disease processes is fundamental. This foundation is built through rigorous coursework and reinforced through practical application.
  • Hands-on animal handling: Practical experience through internships, volunteer work at animal shelters, farm work, or laboratory animal training is non-negotiable. Many veterinary schools require a minimum number of animal-related hours—often 500 or more—for admission. Even careers that don't require veterinary school still expect significant hands-on experience.
  • Communication and empathy: Working with animal owners, researchers, and interdisciplinary teams requires clear written and verbal skills, plus compassion for both animals and their caregivers. Veterinary professionals must be able to explain complex medical information to non-specialists and provide emotional support during difficult decisions.
  • Critical thinking and problem-solving: Diagnosing illness, designing research protocols, or managing conservation crises demand analytical reasoning and the ability to synthesize information from multiple sources.
  • Ethical commitment: Adherence to animal welfare principles—such as the Five Freedoms (freedom from hunger, thirst, discomfort, pain, fear, and freedom to express normal behavior)—and responsible research practices is paramount. Students should familiarize themselves with institutional animal care and use committee (IACUC) protocols if they plan to work in research.
  • Technical proficiency: Familiarity with veterinary practice management software, laboratory equipment, GIS tools for wildlife work, and statistical packages (R, SAS, SPSS) is increasingly expected. Many programs offer elective courses to build these skills.

Certifications can significantly enhance employability. For veterinary technicians, passing the Veterinary Technician National Examination is essential for state licensure. For research roles, AALAS certification is recommended and often required by employers. For wildlife professionals, the Wildlife Society offers the Certified Wildlife Biologist (CWB) credential after a combination of education and professional experience. Students should also consider joining professional organizations like the American Veterinary Medical Association or the Student Chapters of the Wildlife Society for networking and mentorship opportunities.
