Throughout the ages humans have depended on animals for service, food, and companionship. In modern times, animals have even played a crucial role in research settings where diseases are studied and drug therapies are developed.

Veterinary medicine and animal care focus on the provision of health care, surgery, and preventive services for a variety of animal species. Veterinarians and veterinary technicians address health emergencies as well as provide routine medical care. Animal care workers tend to the daily needs of pets and livestock.

This ownership trend has fueled the need for veterinarians and animal care workers. In 2019, Americans spent more than $29 billion on veterinary care services a...
