Which symptom is NOT associated with colic?

Colic in horses refers to various types of abdominal pain and is often accompanied by a range of symptoms. Sweating, pawing at the ground, and rolling or attempting to roll are all common signs of colic as they indicate the horse's discomfort and distress.

Sweating typically occurs due to pain or anxiety, while pawing at the ground can be a way for a horse to express its discomfort or attempt to alleviate it. Rolling is also associated with colic because it signifies the horse's struggle with the pain; horses often try to find a position that relieves discomfort, which may involve rolling.

Shortness of breath, however, is not typically a symptom of colic. While it can occur in horses for various reasons, it is more commonly related to respiratory issues or strenuous activity rather than abdominal pain. Thus, among the listed options, shortness of breath stands out as not being directly linked to colic.
