What is the best initial response if a horse is colicking?

If a horse is colicking, the best initial response is to keep the horse walking. Walking can help stimulate gut movement and alleviate some of the discomfort caused by colic. It is important to help the horse remain calm and mobile, as this can prevent further issues that may arise from lying down or rolling, which could lead to more severe complications.

In contrast, administering a sedative could mask symptoms and delay necessary veterinary treatment. Feeding the horse hay during a colic episode is not advisable, as it may worsen the condition by adding food material to a potentially obstructed gastrointestinal tract. Isolating the horse may not provide any benefit; in fact, being with other horses can help keep the affected horse calm through social interaction. Hence, keeping the horse walking is the most effective way to manage the situation immediately until veterinary help can be provided.
