Gusty J Ranch

Gusty J Ranch breeds miniature donkeys in Guernsey, WY, within Platte County and the North Platte River Valley near Casper. Sandy Johnson has been raising miniature donkeys for more than ten years and holds membership in national donkey associations, complementing regular health testing for hoof, dental and overall veterinary wellness. The ranch spans 120 acres of native grass pasture with sturdy shelters, and foals benefit from daily turnout, early handling and supervised introductions to farm life to build gentle temperaments and confidence.

Breeding decisions follow a philosophy of genetic health and structural soundness, with certified farriers providing timely hoof trims and local veterinarians conducting biannual wellness exams. A blend of pasture grazing and hay supplementation ensures steady weight through Wyoming’s seasonal extremes, while grit boxes and mineral licks support digestive wellbeing. Visitors often note the donkeys’ friendly natures and versatile temperaments, qualities that lend well to therapy programs and small-scale farm chores. Gusty J Ranch reflects a family-centered approach to husbandry, combining traditional open-range practices with attentive, hands-on care.
