As already mentioned, watery droppings are not a disease, but only a symptom that can have many triggers and is a visible consequence of several causes. What does it mean? Let's take an example: Due to massive overweight, the owner of horse "Billy" is advised to go on a diet. Unknowingly, this is initiated too drastically and the amount of hay is greatly reduced from one day to the next. Not only the metabolism of "Billy" has to adjust to this change, but also the psyche of the animal. Horses are very strong creatures of habit. Suddenly not having hay available 24/7 can cause stress and hunger. In our example, this subsequently lead to gastritis. Horses suffer silently, so it is not recognized by the owner. Maybe "Billy" is not so rideable, but this is blamed on the bad mood, since "Billy" is now on a diet. As a result, there is a disbalance in the small and large intestines, which eventually leads to fecal water. This last symptom of a long chain of symptoms is now clearly visible to the horse owner.
