Horseworld's Head of Husbandry, Joanne Vaughan, tells ITV News Westcountry about how Dominic the pig came to live at the animal centre, near Bristol.
A pig is being used to help train firemen. He's being used to help Avon Fire and Rescue Service learn how to herd animals.
The service attends more than a 150 animal emergencies a year. So, to help them prepare, they've called in a fourteen stone Gloucestershire Old Spot cross.
