Which of the following is a sign of colic in horses?

Pawing at the ground is a well-documented sign of colic in horses. When a horse is experiencing gastrointestinal discomfort, it often displays signs of agitation and distress, and pawing is one of those behaviors. This action typically indicates that the horse is uncomfortable or in pain, which is commonly associated with colic.

Colic can manifest in various ways, and recognizing these signs early can be crucial for effective treatment. Pawing is an instinctive response to discomfort, as the horse tries to alleviate stress or pain by disturbing the ground.

While running in circles, excessive drinking, and a coat not shining might indicate other health issues or discomforts, they are not specific indicators of colic. For instance, running in circles could relate to high energy levels or anxiety; excessive drinking may suggest dehydration or other metabolic issues; and a poor coat condition can indicate nutritional deficiencies or other systemic health problems. Detecting pawing, however, specifically points toward the gastrointestinal issues typically seen in cases of colic, making it a key sign for horse owners and caretakers to monitor.
