Lewis Hamilton says he made the "hardest decision of [his] life" to put Roscoe, his 12-year-old bulldog, to sleep. Roscoe died in Hamilton's arms on Sunday evening after being admitted to hospital with pneumonia last week. He had been on life support since Friday, when Ferrari driver Hamilton missed a Formula 1 tyre test in order to spend time with him. Announcing the news to his 40.8m Instagram followers, Hamilton said: "After four days on life support, fighting with every bit of strength he had, I had to make the hardest decision of my life and say goodbye to Roscoe. "He never stopped fighting, right until the very end.
