A dog called Miracle who was saved from the illegal meat trade in Thailand is the star act of this week's Britain's Got Talent.The crossbreed was rescued from a cage stuffed with more than 1000 dogs and adopted by Scot Amanda Leask, who has won awards for her work with rescue dogs.Simon Cowell and his fellow judges were moved to tears after she told them: "Miracle has been at the heart of our family for six years but he wasn't always as happy and healthy as he is today."He spent the early part of his life in unimaginable conditions as a victim of the dog meat trade."When the rescuer first saw him she thought he was dead but when her camera flashed, he opened an eye."It was a miracle he was still alive."We brought him back to Scotland and
