Veterinary science is the branch of medicine that focuses on the health and well-being of animals. It involves diagnosing, treating, and preventing diseases in various species, including pets like dogs and cats, as well as livestock such as cows and sheep. Veterinarians, the professionals in this field, use their knowledge to ensure animals receive proper care and maintain public health. In addition to treating injuries and illnesses, veterinary science also includes research on animal diseases and the development of vaccines. This field plays a crucial role in understanding zoonotic diseases, which are illnesses that can be transmitted from animals to humans, helping to protect both animal and human populations.
