Panorama sent a reporter undercover for nine months to work as a trainee at one of the country's biggest veterinary chains.

During her time at Medivet, the reporter found evidence of inexperienced and unqualified staff carrying out medical procedures.

Here, she and a colleague - a fellow trainee - attempt to help prepare an Irish Setter called Yogi for an operation.
