I am totally favorable to full disclosure and full transparency regarding veterinary student assistance or practice regarding my family members--often considered pets.  I want to be told in advance if a student is being asked to offer any service for my family and this should be a minimum standard.  What level and type of service and level of supervision by the practicing vet needs full disclosure in advance as well.  I like the model I have seen used in some physicians office.  The Dr says am I willing to see the doctor in training, I say yes, the in training doc does an exam, makes recommendations, then my regular physician comes back in and reviews all with me present.  And sometimes a discussion happens about recommendations because agreement is not automatic.  I'm for this kind of supervised learning.  And beyond diagnosis right up to practice where an intern is supervised on site when surgery is required.
