Animal Therapy Research Findings

John Ioannides, MD, Stanford Medicine, has challenged his healthcare peers’ misleading and simply wrong clinical research. In fact, he claims that 80 percent of non-randomized studies and 25 percent of randomized studies are wrong.

And yet, the evidence-based standard of care and clinical protocols continue to be based on these research outcomes.

So are these research challenges also applicable to Animal Therapy (aka Animal-assisted Therapy)?

As with clinical research in the rest of healthcare … there remains questions.

See: Does Animal-Assisted Therapy Really Work? by Hal Herzog Ph.D., Animals and Us in Psychology Today.


That said, here is some of the better research in this space:
