The third season of the popular veterinary series, The Supervet, returns to SBS as Professor Noel Fitzpatrick and his team treat the hardest to cure animals with cutting-edge treatments. Hetty the Labrador is unique. She is the first dog to have been trained both as a guide dog for the blind and a seizure alert dog. Not only does she help Toni, a mother-of-two who is blind, live an active life, but she also warns Toni if she is about to have an epileptic fit. However, Hetty has become lame on both her front legs and has been referred to Professor Noel Fitzpatrick. Invasive surgery could mean Hetty will be out of action for as long as four months, a terrifying thought for Toni, who will be without her lifeline. The pressure is on for Noel to get Hetty back to full working health as soon as possible.
