One of the occasional arguments used in support of “alternative” approaches to human medicine is the observation that since “alternative” medicine is used (with anecdotal success) in animals, and animals don’t know anything about the treatment that they’re getting, then they must work a priori. Of course, the fallacy of such an observation is pretty obvious to anyone with a logical/skeptical frame of mind, because it assumes that the therapies do work (even though there’s little evidence of that).
Clearly, however, some people perceive that the therapies work, including veterinarians – there are veterinary acupuncturists, chiropractors, homeopaths, etc., etc. Since there’s very little scientific support for the idea that the therapies actually have any clinically significant effect on biological processes, including the processes that result in disease, questions arise as to whether there are other effects of “alternative” treatments on animals. Specifically, people may wonder whether or not animals can benefit from placebo effects.
