Vet Niamh Lewis is looking after one of the latest admissions, a heavily pregnant horse called Destiny. The weight of Destiny's pregnancy is causing her abdominal muscles to tear. This means that she is likely to struggle during labour, as her torn muscles mean she will not have enough strength to push properly. With Destiny's due date approaching, Niamh checks on her patient. Destiny has started producing milk, which means foaling is imminent.
