Veterinary medicine is the branch of medicine that deals with the prevention, control, diagnosis, and treatment of disease, disorder, and injury in animals. Along with this, it deals with animal rearing, husbandry, breeding, research on nutrition, and product development.

For pet owners, veterinarians, and farmers and ranchers, medicines are essential for ensuring animal welfare, preventing diseases from passing between animals and humans, and protecting our food supply.

There are three types of animal medicine: biologics (which are predominately vaccines), pharmaceuticals, and flea and tick medications.
