Tommy the donkey was born with a weak front right leg. Walking and standing were difficult, as he placed nearly 60% of his body weight on that single leg. As a result this strained his spine and shoulder. Dorset Orthopaedic, a prosthetic company, fitted the animal with a prosthetic leg which he wears every morning. Tommy is now able to enjoy walking, standing, and eating ginger nut biscuits, his favorite treat.
