I have been following since the beginning Ms. Henkel's faithful commitment to protect our pets and the students who are practicing their veterinary skills on them by her insistance that this practice only be with signed owner consent.  As a retired clinical social worker, I recall the many times I asked clients to allow me as a student to be their social worker.  Some declined and I did not fault them, assuring them that if my precious life or that of my child were on the line, I might say 'no' as well.  Most gave permission, often saying that they thought they might get better care because 2 heads (mine and that of my superisor) might be better than one.  And many realized how hard students try, another benefit of their being involved.  I will not rest easy ,and I am very sure that Ms. Henkel will not rest at all, until owners are fully involved in care of their pets.  Let's not waste time by doing it any other way and lets be ethical.
