How do you cart train a Shetland pony?

To cart train a Shetland pony, start by familiarizing it with the harness and cart in a safe, enclosed area. Gradually introduce the pony to the cart by first allowing it to explore and then attaching the harness without the cart, ensuring it is comfortable with the equipment. Once the pony is accustomed to the harness, attach the cart and begin with short sessions, rewarding the pony for calm behavior. Always prioritize safety and be patient, gradually increasing the duration and complexity of the training as the pony gains confidence.
