Miniature horses need the same basic care as their larger counterparts, but also have a few additional requirements. Sheryl Peterson (Oak Bay Acres, near Portland, Oregon) has raised miniature horses for 40 years and is a member of the American Miniature Horse Association. She manages her minis like her other horses.
“In the spring, you don’t turn them out on lush spring grass; they must be introduced slowly and gradually to grass or they might founder,” she said. Early morning grass contains more sugar, so letting them out to graze later in the day helps prevent metabolic problems and overweight issues.
