Ashleigh and Pudsey become first ever dog trick act to win Britain's Got Talent The teenager trained her pet to jump, dance on his hind legs, meander through her legs and even got him to run across the judges table. Pudsey - a border collie, bichon frise and Chinese crested cross - obviously won over fearsome judge Simon Cowell, who admitted he has a soft spot for dogs. He said the pair were one of his "favourite ever acts." After their performance, he joked: "I actually think Pudsey is training you now. I adore both you. You you have got better and better as the competition has progressed and to do what you did in such a short time is a miracle. Comedian panellist David Walliams told the teen: "I don't know how long it takes to train Pudsey but it is the third original act we have seen from you which is extraordinary. The nation has fallen in love, not just with Pudsey but with you too. Miss Butler joked that Pudsey had become "very diva-ish" during the last week, demanding steak dinners. The pair won £500,000 and will perform their routine at the Royal Variety Performance in front of the Queen. The pair beat off stiff competition from dance troupes, synchronised swimmers and a Welsh choir. Their win came as a shock to bookies who placed pop-opera duo Jonathan and Charlotte, aged 17 and 16 respectively, as the hot favourites. The teens, from Ilford, Essex, came in second place after their their "sensational" performance of The Prayer. The duo stuck together despite Cowell suggesting Jonathan should go solo during their first audition. Walliams told them: "That was sensational. That was your best performance yet, it was so heartfelt, it was so professional. Welsh boys choir Only Boys Aloud came in third place after their rendition of Calon Lan. The 133-strong choir consistently wowed the judges throughout the contest with their renditions of traditional anthems. Judge Alesha Dixon, who was sporting a see through floor length gown over a shimmering leotard, told boys, aged between 14 to 19, that they gave a passionate performance. She said: "That was a really special moment. I could feel the passion coming from every single one of you. I commend each and every one of you and I am so glad that once again you choice to stick to your tradition and sing something Welsh. Cowell joked: "This is why I love this show because I got emotional listening to a song that I didn't understand a word of. But I could tell how much it means to every one of you individually. Every single one of you gave it 100%. Boyband The Mend kicked off the show after being voted back on as the wildcard. Amanda Holden said their version of the David Guetta and Usher track Without You was "fantastic." The judge gave the panel an air of Hollywood glamour with her curled locks tied up and a figure hugging fish-tail ivory gown. Other acts which made the final included singers Sam Kelly and Ryan O'Shaugnessy, synchronised swimmers Aquabatique and Welsh dance group Nu Sxool. Youngster Molly Rainford also impressed the audience with her rendition of Ava Maria. The 11-year-old told Ant and Dec it felt like a "dream come true" to perform on the show.
