You must ensure that you have adequate space (most counties and towns demand at least 5 acres of grazing land), that you can fence the area, and that you leave enough room for the number of horses you have (many areas require one acre per horse). Some farmers keep multiple breeds of horses so they have some to trade with other farmers or people who own horses but are unable to use them. In most cases, horses are allowed on agricultural land, which includes pasture land and farms. However, you should check with your local government before letting your horse run free since they may have regulations about where they can go. For example, some cities will not allow horses in wooded areas because of the danger posed by trees falling on power lines or roads. Horses also need exercise and recreation, so make sure there is an open field nearby where they can go if you are not able to give them a full ride every day. If you want to keep horses as a hobby or form a business, you will need at least 5 acres. You can either purchase land or rent space. If you choose to buy land, then you should look for farmland that is for sale rather than owned land since it will be easier to find acreage that is close together rather than having some land that is far away from another source of income.
