Veterinarians (vets) provide animal health and welfare services. The types of animals range from domesticated pets or livestock, to wildlife (whether they live on land, water, or air), or even certain types of ecologically important insects, such as bees. Vets are also involved in research, regulation, and management regarding food safety, public health, and environmental decisions. In general, they:
- Perform routine, emergency, and post-mortem animal exams
- Diagnose diseases
- Provide advice about preventive health care and herd health
- Vaccinate animals against infectious diseases
- Treat a wide range of injuries and illnesses
- Perform dental work
- Perform surgery
- Provide obstetrical and embryo transfer services

Diagnosing and treating diseases, injuries, and other conditions often involves:
- Collecting, examining, and studying samples including body tissue, feces, blood, urine, or other body fluids
- Taking and reading X-rays

Veterinarians who work with large animals may focus their practice on herd health. In this area, herd management, monitoring, and regulatory medicine are important.
Vets are often small business owners who run their own private practice. They must manage human resources, finances, and inventory, and market the business.
Some vets become representatives for food or drug companies. They share information about products or practices and ensure product efficacy and food safety.
Veterinarians may provide a wide range of services in various other industries. These include wildlife conservation, public health, food safety, agriculture development, disease surveillance, or animal welfare services.
