Teen trainer Ashleigh Butler and her dancing dog, Pudsey, have won the top prize on "Britain's Got Talent."

The BBC said judge Simon Cowell described the duo as one of his "favorite ever acts."

The team won $804,000 on Saturday's finale, which was seen by 14.5 million people.

"I just want to say thank you to everyone that voted for me, and I'm just so proud of Pudsey," Butler, 17, said as she hugged her dog -- a border collie, bichon frise and Chinese crested mix -- and told him, "I love you."
