Dog trainer Jules O'Dwyer and her dog Matisse have won Britain's Got Talent 2015.
It's the second time that a dog has managed to take the top spot in the competition after Ashleigh Butler and her dog Pudsey won the show in 2012.
"I can't believe that we've just won Britain's Got Talent," Jules told Newsbeat. "Super, amazing, amazing."
They will perform in this year's Royal Variety Performance and take home a cash prize of £250,000.
The final drew 13.4 million viewers on Sunday night, with the show becoming this year's highest rating programme on TV so far.
A clearly emotional Jules told Newsbeat after the victory that Matisse would get lots of treats.
"[I've] not really had time to think about what we are going to do with the money. Obviously I'm going to get all my dogs lots of gifts and treats and toys and everything else.
"My daughter is begging me for a new phone. I'm pretty sure she's going to get her wish."
The pair beat magician Jamie Raven and Welsh choir Cor Glanaethwy in the final three.
A different dog, a stunt double, walked across a tightrope in a performance described by Simon Cowell as "one of the best dog acts we've ever seen".
Out of the final 12, two were announced on the evening as wildcard choices, with the public wildcard vote going to nine-year-old Jesse-Jane McParland and the judges' wildcard choice was dance group, Boyband.
TV hosts Ant and Dec said the show had received a total of four and a half million votes.
The top nine spots went to, in order from last to fourth: Boyband, Entity Allstars, U D I, The Neales, Jesse-Jane McParland, Danny Posthill, Calum Scott, Isaac Waddington and in fourth place, Old Men Grooving.
Guest performers on the show were Lord of the Dance's Michael Flatley and singer Andrea Bocelli.
Flatley confirmed on the show that his BGT performance would be his last UK TV performance.
