If you are considering getting a miniature horse as a pet, it’s helpful to know a bit about their care and health. It's true that they cost less and eat less than a full sized horse, therefore the initial cost will be less and you also won't spend that much on the feed. But they still require the same vet and farrier care that full-sized horses require, including vaccinations, teeth floating, and hoof trims. So while a mini can be cheaper to own, it doesn't mean you won't have to invest a lot of money in your horse's care.
