An equine pain face

As in humans animals show pain through facial expression. This study investigated the facial expressions in horses during induced pain.

Facial expressions changed in all horses during pain inductions and made changes in ear positions, eyes, nostrils and muscle tension. These alterations were not static and also weren’t seen all at the same time. The authors of the article made a very clear overview in the form of a table and described every facial feature separately. See table below.
