Here is some important information regarding becoming a trainer.
You must be between the ages of 8-18 years and have prior horse experience. Full support of your parents/guardians is a must. There are also two letters of recommendations required with your application.
You must provide a minimum of 400 square feet (20 feet x 20 feet) for each animal adopted. Horses less than 18 months of age should be kept in corrals with fences 5 feet high. Fences must be at least 4.5 feet high for ungentled burros and 6 feet high for ungentled horses more than 18 months of age. You should not release an ungentled animal into a large open area, such as a pasture, since you may not be able to recapture the animal for training or to provide veterinary care. However, once the animal is gentled, you may release it into a pasture or similar area.
The acceptable corral must be sturdy and constructed out of poles, pipes, or planks (minimum 1.5 inch thickness) without dangerous protrusions. Barbed wire, large mesh woven, stranded and electric materials are unacceptable for fencing. Posts should be a minimum of 6 inches in diameter and spaced no farther than 8 feet apart. Horizontal rails should be 3-inch minimum diameter poles or planks at least 2 feet x 8 feet. If you use poles, there should be a minimum of five horizontal rails, and when you use 2″ x 8″ planks, there should be at least four rails. No space between rails should exceed 12″. You should fasten all rails to the inside of the post with either heavy nails or lag screws.
You must provide shelter from inclement weather and temperature extremes for your adopted wild horse or burro. Shelters must be a two-sided structure with a roof, well drained, adequately ventilated, and accessible to the animal(s). The two sides need to block the prevailing winds and need to protect the major part of the bodies of the horse or burro. Tarps are not acceptable.
