[2] Ultimately, the housing condition of horses is considered to be the cause of stable vices such as weaving.Domestic horses are often housed in stalls (typically 8x8 or 12x12) at night, and are allowed turnout (i.e. time outside) during the day.Horses also sometimes weave near a window to the aisle or the exterior of the stable, which would provide visual stimulation.[3] However, some horses that have developed the habit will also weave while turned out, signifying that the problem is not solely one of confinement.[2] Weaving is generally not a very damaging vice over short periods of time, but horses that are consistent weavers may show abnormal hoof wear, and stress on their joints (which can cause lameness).
Providing visual stimulation (an open window to the outside) to a stalled horse reduces risk of stable vice occurrence
Providing a large turnout area, and free-choice hay reduces stress by mimicking a horses natural environment, and therefore reduces risk of weaving behaviour.
