Which of the following is a common sign of a horse experiencing stress?

A common sign of a horse experiencing stress is excessive sweating or pacing. When a horse is stressed, its body can react in various ways, and these behaviors are indicators of that heightened state of anxiety or discomfort.

Excessive sweating is a physiological response, often triggered by an increase in adrenaline when the horse feels threatened or uneasy. This sweating can occur even in cooler temperatures or without physical exertion. Pacing, on the other hand, is a behavioral response where the horse moves back and forth in a specific area, which signifies restlessness and a need to cope with its unease.

The presence of these signs serves as an important signal for caretakers to recognize and address the horse's emotional state, ensuring that appropriate measures are taken to alleviate stress and promote well-being.
