The views of veterinarians towards the changes that are occurring in professional practice with respect to competition and advertising are examined and compared with the views expressed in a similar study carried out 3 years previously. Data was derived from self completion questionnaires containing 40 Likert scales which were mailed to 300 members of the profession, first in 1985 and then in 1988. The moves made by the New Zealand Veterinary Association since 1985 in relaxing the rules on promotion appear to have largely alleviated any frustrations that were building up amongst the membership at that time. However, the study suggests that the profession will still find the boundaries of acceptable behaviour being tested by entrepreneurial practitioners. (author)
