Doctors of Veterinary Medicine and Veterinary Surgeons are medical professionals whose primary responsibility is protecting the health and welfare of animals and people. The term "veterinarian" comes from veterinae, which means "working animals." Every veterinarian has gone through extensive medical training for animals and has received a license to practice veterinary medicine.
Veterinarians diagnose and control animal diseases, treat sick and injured animals, prevent the transmission of animal diseases to people, and advise owners on proper care of pets and livestock. They ensure a safe food supply by maintaining the health of food animals. Veterinarians are also involved in wildlife preservation and conservation and public health of the human population.
You are probably most familiar with veterinarians who specialize in pet medicine in a clinical setting such as an animal hospital or veterinary clinic. During each visit, this type of veterinarian will be able to guide you in all aspects of pet maintenance, including food requirements, daily care, and any special needs. They will also be able to provide vaccinations, complete surgery, and even prescribe medicines as needed.
