Veterinarians are dedicated professionals who specialize in maintaining and improving the health of animals, including pets, livestock, and those in zoos or wildlife preserves. Their responsibilities encompass a wide range of medical, surgical, dental, and rehabilitative care for sick or injured animals. Veterinarians diagnose diseases, prescribe medications, administer vaccinations, and educate pet owners on topics like weight management and senior pet care. Some contribute to public health by studying diseases that affect both animals and humans or by serving as food safety inspectors. Others engage in research to advance animal welfare and publish their findings in veterinary journals.
