revised veterinarian's oath

The concept of animal welfare is not new, but recognition by an organization that represents U.S. veterinarians is a huge step forward for animals.  The revised oath is as follows with the additions in italics:

"Being admitted to the profession of veterinary medicine, I solemnly swear to use my scientific knowledge and skills for the benefit of society through the protection of animal health and welfare, the prevention and relief of animal suffering, the conservation of animal resources, the promotion of public health, and the advancement of medical knowledge.  I will practice my profession conscientiously, with dignity, and in keeping with the principles of veterinary medical ethics.  I accept as a lifelong obligation the continual improvement of my professional knowledge and competence."

Animal welfare can be defined as not just the physical but the mental well-being of non-humans.  Concern for a creature's psychological well-being implies recognition that an animal is a sentient being with feelings of pain, pleasure, joy, sadness, fear -- all emotions.  Before the 19th century, the idea of animals having emotions wasn't considered very much.
