[header] How to shelter a horse [title] Build a three-sided shelter to protect your horse from the elements. [step] At a minimum, a horse should have access to a three-sided shelter with a waterproof roof. To provide maximum protection against drafts, place the structure against the prevailing winds in your area. 
[substeps] For example, if winds typically blow from the north and west, position the shelter so the open side faces the southeast. The three-sided shed should be big enough to fully cover all the horses that you keep in your field.
