A sheepdog that had to have a leg amputated after going missing is still expertly rounding up animals in Perthshire. Boss, a border collie, went missing for eight days, before being spotted limping over a hill on the Amulree farm. Due to nerve damage, the four-year-old pooch had to have a leg amputated. The sheepdog defiantly went back to chasing sheep just three weeks after having stitches removed.
