Dog act Jules and Matisse have won the final of Britain's Got Talent.

After weeks of auditions, twelve acts, selected from thousands of hopeful auditionees, took to the stage in the hope of winning the chance to perform at the Royal Variety Show this year and claim the £250,000 prize money.

But it was the heart-warming canine caper performed by Matisse and his owner Jules who left judge David Walliams in tears and finally won over the British public.

The final act of the night, they staged a skit with a cops and robbers theme which ended in a three–legged dog named Skippy joining them on stage in an emotional ending.

A visibly moved Walliams said that after seeing the touching performance he was switching from being "a cat person to a dog person."

Amanda Holden, who was also reduced to tears said: "Honestly it was just one of the most wonderful story, I'm crying my eyes out it's pathetic. You've knocked it out the park."

Famed for being a dog lover, Simon Cowell said: "It is your love for that dog which really really shows, maybe we just saved the best until last."

The canine act follows on form the success of the 2012 winner Pudesy, who went on to star in a movie and have a book published.

While Jules was overwhelmed at winning the entire talent competition, there was disappointment for the rest of the acts.

Runner up, magician Jamie Raven left the audiences and the judges astounded by his magic tricks.

A strong contender to win the show outright, he performed a startling money trick that prompted a slightly bewildered Alesha Dixon to yell "shut the front door."

"Seriously, you must be a wizard or something," said Cowell while Holden told Jamie: "I'm astounded. Tonight that felt like an act you could do anywhere in the world right now, it was just extraordinary.'

But after losing the competition to a dog, he was gracious in defeat.

"I can at least say that I was the best human in the 2015 show," he joked as the final results were announced.

Another strong act was singer Calum Scott, Simon Cowell's Golden buzzer act, however he blew his chances of walking away with the title when he forgot the words to Rihanna's Diamonds in the opening half of the song.

Cowell attempted to highlight the positive aspects of the performance saying: "Calum you know what, I was talking to some press the other day and saying "you're the red hot favourite to win", but you don't know what's going to happen until the final. It fell apart in the first part. Luckily on the second part of the song you picked it up... I hope that people judge you on the second part."

Dixon sympathised adding: "Every performer and artist will relate to you, it happens. You deserve to be in this competition."

The final also included performances by 160 piece choir Cor Glanethwy who sang Hallelujah; Essex dance troupe Entity Allstars kicked off the grand final with a spectacular gladiator themed routine and Siberian dance troupe UDI whose performance incorporated a tale of good versus evil.

But in the end, none of the performers were able to outshine Jules and Matisse's shaggy dog story.
