Upon arriving at Jamieson Ranch, guests soon discover our eager and friendly miniature horses grazing in their pristine pasture. These "minis" are their own distinct breed of horse, measuring 38 inches in height or less. Trained as assistance or service animals for people with disabilities, our "minis" may be small in stature, but they make a big impact by bringing light into the lives of everyone they meet. Jamieson Ranch Vineyards has formed the Light Horse Foundation, dedicated to helping at-risk individuals, particularly those with autism, and supporting other important humanitarian causes. A portion of our profits will go to support the Light Horse Foundation.
