In this programme, Javier Rincon performs complex surgery on a seven-month-old dog under the guidance of Professor Donald Yool at Glasgow Vet School. Poppy has a shunt – an extra blood vessel that bypasses her liver and the risky surgery is essential. It's lambing season in Stornoway and Joanna Jackson is constantly on the road. At Five Sisters Zoo, the keepers have the challenge of catching Mo the gibbon so that Romain Pizzi can anaesthetise her. He wants to carry out some blood tests to find out why she's not been well.
