Cushing's vs. EMS vs. Low Thyroid

The Horse has a great article on the difference between Equine Cushing's Disease, Equine Metabolic Syndrome, and Hypothyroidism.

In the past there has been a lot of confusion between these three conditions. In that last couple of years a lot of clarity has been brought to this issue. This article breaks it down is a very clear (and brief) way.

Judging from this cave painting this is not a new issue :-)
