American society is becoming increasingly interested in issues of animal welfare, and the public generally recognizes the need for guidance from experts in the field. Assessing an animal's welfare status requires a determination of the state of both its physical and its psychological well-being. American veterinarians are well trained to assess the physical state of most animals, but they do not receive equivalent training in assessing an animal's psychological state. Therefore, the recognized expertise of the American veterinary profession currently lies only in answering physical welfare questions, not in assessing the psychological (or societal) aspects of animal welfare issues. If American veterinarians wish to be seen as animal welfare experts, then it is critical for the profession to educate its members in assessing the psychological state of animals. Also, if the American Veterinary Medical Association wishes to be considered a leader in the field of animal welfare, it must partner with organizations with expertise in pertinent areas outside of the veterinary medical field to develop appropriate guidelines for American society, including the development of a widely accepted system for defining and determining overall animal welfare. If American veterinarians actively work to improve our strengths and combine them with those of experts in other fields, we can overcome our limitations as animal welfare experts and achieve wider acceptance as an important force for improving animal welfare.
