Animal Science: Careers, Education & Certifications
Animal science sits at the intersection of biology, agriculture, behavior, and veterinary medicine. The field employs roughly 33,800 animal scientists in the United States as of 2025, according to the Bureau of Labor Statistics. Thousands more work in adjacent roles: veterinary technicians, animal behaviorists, shelter directors, dog trainers, wildlife biologists.
This page covers the field from top to bottom. What animal science actually is. What jobs exist. What degrees and certifications you need. What they pay. And where the field is headed as technology reshapes animal care, research, and agriculture.
What Is Animal Science?
Animal science is the study of animals under human management. That includes livestock, companion animals, laboratory animals, and captive wildlife. The discipline covers genetics, nutrition, reproduction, physiology, and behavior.
It is not the same as zoology, which focuses on wild animals in their natural ecosystems. Animal science is applied. The goal is practical: improve animal health, welfare, production efficiency, or the human-animal bond. A zoologist might study wolf pack dynamics in Yellowstone. An animal scientist studies how early socialization protocols reduce aggression in shelter dogs.
The field branches into several specializations:
- Companion animal science — behavior, training, nutrition, and welfare of dogs, cats, horses, and other pets
- Livestock science — cattle, poultry, swine, and small ruminant production and management
- Animal behavior (ethology) — applied behavior analysis, behavioral modification, welfare assessment
- Animal nutrition — feed formulation, dietary requirements, clinical nutrition
- Reproductive science — breeding programs, artificial insemination, embryo transfer
- Shelter and rescue management — intake protocols, adoption programs, community outreach, euthanasia reduction

Career Paths in Animal Science
The career range is wider than most students realize. Here are the primary tracks, with realistic salary ranges based on 2025 BLS data and industry surveys.
Animal Behaviorist
Applied animal behaviorists work with pet owners, shelters, zoos, and veterinary clinics to diagnose and treat behavioral problems. Board-certified applied animal behaviorists (CAAB) earn $55,000 to $92,000 depending on location and caseload. The path requires a master’s or doctoral degree and supervised experience. Our guide to becoming an animal behaviorist covers every step.
Dog Trainer
Professional dog training is one of the fastest entry points into the animal field. The industry generated $9.2 billion in the U.S. in 2024. Certified trainers holding the CPDT-KA credential earn $35,000 to $65,000 annually. Independent trainers with established businesses can exceed $100,000. Multiple certification programs exist, with significant differences in rigor, cost, and employer recognition.
Veterinary Technician
Vet techs are the backbone of clinical veterinary medicine. The BLS projects 20% job growth for veterinary technologists and technicians through 2032 — far above the national average. Median pay is $38,240, with top earners in emergency and specialty practices hitting $52,000+. The role requires an associate degree from an AVMA-accredited program and passing the Veterinary Technician National Examination (VTNE). Full details in our vet tech career path guide.
Animal Shelter Manager / Director
Shelter management combines animal welfare knowledge with nonprofit administration. Directors at mid-size shelters earn $45,000 to $75,000. Large metro shelters and humane societies pay directors $80,000 to $120,000+. The Certified Animal Welfare Administrator (CAWA) credential, offered by the Association for Animal Welfare Advancement, is the industry standard. Read our shelter management career guide.
Pet Nutritionist
Pet nutrition is a growing specialization driven by the $58.1 billion U.S. pet food market. Board-certified veterinary nutritionists (ACVN diplomates) earn $90,000 to $150,000+. Non-veterinary pet nutrition consultants with certification earn $40,000 to $70,000. See our review of pet nutrition certification programs.

Education Requirements
Education paths vary dramatically by career goal. A dog trainer can start working with a high school diploma and a certification course. A board-certified veterinary behaviorist needs a DVM plus a residency. Here is the breakdown by degree level.
Associate Degree (2 years)
Sufficient for veterinary technician roles and some animal care positions. AVMA-accredited programs are the standard. Cost: $8,000 to $25,000 at community colleges; $20,000 to $45,000 at private institutions.
Bachelor’s Degree (4 years)
The baseline for most professional roles. A BS in Animal Science covers core coursework in anatomy, physiology, genetics, nutrition, and animal management. Strong programs include Colorado State University, UC Davis, Texas A&M, Cornell, and the University of Florida. Average annual tuition at public universities: $10,000 to $15,000 in-state. For students considering online options, see our guide to the best online animal science programs.
Master’s Degree (2-3 years)
Required for applied animal behaviorist certification (CAAB) and many research positions. An MS in animal science, animal behavior, or a related field adds specialization depth. Funded positions (teaching or research assistantship) cover tuition plus a $18,000 to $26,000 annual stipend. Unfunded programs cost $30,000 to $80,000 total.
Doctoral Degree (4-6 years)
Necessary for university faculty positions, CAAB certification at the doctoral level, and senior research roles. Nearly all PhD students in animal science receive full funding. Our animal behavior degree guide walks through the decision of MS vs. PhD.
Online and Distance Learning
Online programs have expanded access to animal science education, but the field’s lab and hands-on requirements create specific challenges. Accredited online programs handle this through hybrid formats, local externship placements, and intensive on-campus residencies. We break this down in distance learning in animal science.

Digital Tools Reshaping Animal Science
Technology is changing how animal professionals work, collect data, and communicate with clients.
Telehealth and Virtual Consulting
Veterinary telehealth grew 300% between 2019 and 2023. Animal behaviorists now conduct 30-40% of consultations via video. Platforms like TeleTails and Vetster have created new revenue streams for practitioners. The American Veterinary Medical Association updated its telehealth guidelines in 2024 to reflect this shift.
Data Collection and Analysis
Wearable sensors (FitBark, Whistle, PetPace) generate behavioral and physiological data that animal scientists use in research and clinical work. GPS collars track wildlife movement for conservation studies. Precision livestock farming uses RFID, thermal imaging, and automated weighing systems to monitor individual animals in herds of thousands.
Online Marketing for Animal Professionals
Private-practice animal behaviorists, dog trainers, and veterinary consultants increasingly need digital skills to build client bases. Search engine visibility, social media content, and email marketing are no longer optional for independent practitioners.
AI and Machine Learning
Computer vision systems now automate behavior coding in research settings — a task that previously required hundreds of hours of human observation. Natural language processing tools analyze veterinary medical records to identify disease patterns. These tools create new roles at the intersection of animal science and data science.
Job Market Outlook
The overall picture is positive but uneven. Veterinary technology leads with 20% projected growth through 2032. Animal scientist roles grow at 6%, roughly matching the national average. Dog training and animal behavior consulting are expanding but remain fragmented — most practitioners are self-employed.
Geographic demand varies. California, Texas, Florida, New York, and Colorado consistently have the most job postings for animal science professionals. Rural areas offer strong livestock science positions but fewer companion animal roles.
The pet industry continues to grow. Americans spent $147 billion on their pets in 2024, up from $136.8 billion in 2022. This spending fuels demand across veterinary care, pet food, pet services, and pet technology — all areas where animal science graduates find work.
How to Get Started
- Identify your specific interest. Companion animals? Livestock? Wildlife? Research? Clinical work? The path differs for each.
- Check credential requirements for your target role. Some jobs require specific degrees or certifications. Others value experience over education.
- Start with the right degree level. Do not assume you need a PhD. Many animal science careers require only a bachelor’s or an associate degree plus certification.
- Get hands-on experience early. Volunteer at shelters, intern at veterinary clinics, work on farms. Practical experience matters as much as coursework.
- Consider online and hybrid programs if you are working or cannot relocate. Accredited options exist at every level. See our online programs guide.
Frequently Asked Questions
What degree do I need to work in animal science?
It depends on the role. Veterinary technicians need an associate degree. Most professional roles require a bachelor’s in animal science or a related field. Applied animal behaviorists need a master’s or doctoral degree. Dog trainers can enter the field with certification courses that take 6 to 18 months.
Is animal science a good career?
For people genuinely interested in animals, yes. Job growth is solid across most specializations. Salaries range from $35,000 for entry-level positions to $150,000+ for veterinary specialists and senior researchers. The emotional reward is high, but burnout is real — particularly in shelter work and veterinary medicine.
Can I study animal science online?
Partially. Several accredited universities offer online bachelor’s and master’s degrees in animal science. However, the field requires hands-on training, so most programs include in-person labs, externships, or intensive campus residencies. Fully online programs exist but have limitations. See our distance learning guide for specifics.
What is the difference between animal science and veterinary science?
Animal science is a broader discipline covering nutrition, genetics, behavior, production, and management. Veterinary science (veterinary medicine) focuses specifically on diagnosing and treating animal diseases. Veterinary science requires a Doctor of Veterinary Medicine (DVM) degree. Animal science degrees lead to research, consulting, training, management, and industry roles outside of clinical veterinary practice.
What certifications increase salary in animal science?
The CAAB or ACVB credential significantly increases earning potential for behaviorists. The CPDT-KA raises a dog trainer’s credibility and hourly rate by 20-40%. CAWA certification is increasingly required for shelter director positions. Board certification in any veterinary specialty (nutrition, behavior, internal medicine) can double a veterinarian’s salary compared to general practice.
