What is a disadvantage of using sand as bedding?

Using sand as bedding can significantly increase the risk of colic in horses. When horses ingest sand while grazing or due to sand's presence in their environment, it can accumulate in their gastrointestinal tract. This accumulation may lead to blockages or irritation, resulting in colic, which is a severe and sometimes life-threatening condition characterized by abdominal pain.

While some bedding materials may be expensive to maintain, or high maintenance due to regular cleaning needs, these factors do not directly correlate to the serious health risks associated with sand bedding. Additionally, sand is generally easy to obtain, especially in coastal areas, which may make it a more popular option despite its disadvantages. However, the notable risk of colic distinguishes it as a significant concern among equine caretakers when considering bedding options.
